The scope of this page is limited to discussion of gender affirming voice and communication.
Language is dynamic and terminology evolves. Use of terminology on this page reflects best practices and global research that spans several decades. International use of terminology may not be consistent with use in the United States. Prior research and journal articles may use titles and language that are no longer used. Eliminating this formative research would erase years of content intended to guide best practices. However, clinicians ask their client what terminology they use. Terminology on this page is monitored on an ongoing basis. If you note terminology that you feel should be updated, please contact ASHA.
People may seek gender affirmation services to make their voice and/or other aspects of their communication congruent with their gender and/or gender expression. Speech-language pathologists (SLPs) provide expertise in modifying the voice and other aspects of communication. The SLP assesses a variety of aspects of verbal and nonverbal communication, such as vocal pitch, intonation, voice quality, resonance, fluency, articulation, pragmatics, and nonverbal vocalizations (such as laughing and coughing). An SLP can provide gender affirming voice in various care settings. Health policy, coverage, and reimbursement may use terminology (e.g., transgender and gender diverse, gender dysphoria) that does not always match how the client self-identifies. Some clients may use different terms such as transgender and gender-nonconforming. Be sure to ask how your client identifies and which terms they use. At this time, a medical diagnosis of gender dysphoria may be required to ensure coverage of insurance services, but not all people seeking gender affirming voice services have gender dysphoria.
Studies indicate that a voice that is incongruent with gender identity can negatively impact quality of life, in addition to attracting unwanted attention and greatly impacting safety (Nobili et al., 2018; Oates & Dacakis, 2015). Culturally appropriate and responsive services include having current knowledge of appropriate, inclusive, and nonpathologizing terminology. Terminology continues to evolve. There may be times when people use more than one name and/or pronoun. It is important to know which name and pronouns to use depending on the setting or situation. Privacy and safety are of the utmost importance. Clinicians are mindful of potential barriers and facilitators that influence the client’s day-to-day functioning and communication.
Speech-language pathologists (SLPs) play a central role in clinical services for gender affirmation. The professional roles and activities in speech-language pathology include clinical and educational services (differential diagnosis, assessment, planning, and treatment), prevention and advocacy, counseling, administration, and research. See ASHA’s Scope of Practice in Speech-Language Pathology.
Appropriate roles for SLPs include, but are not limited to, the following:
As indicated in Principle II, Rule A of the ASHA Code of Ethics (ASHA, 2023), SLPs who serve this population should be specifically educated and appropriately trained to do so. The World Professional Association for Transgender Health (WPATH) has developed standards of care for health care professionals working with people who are transgender and gender-nonconforming, including resources on providing voice and communication services. This guidance may help determine prerequisite skills and clinical considerations. In addition, WPATH outlines additional services and treatments by health care professionals, which may provide a baseline of information for practitioners (Coleman et al., 2022).
Please see the Ethics and State and Federal Regulations sections below for more ethical and regulatory considerations.
Gender, as a social construct, is often represented—and oversimplified—by the binary system of male and female. Over time, many have recognized that their gender may not align with the sex assigned at birth. Gender does not fit into a binary construct. Expanding response options to questions about gender and examining how we ask questions are important to ensure that goals and outcomes are patient centered. Clinicians proactively remain educated and up to date with terms that are still evolving and may become outdated and/or offensive. It is essential for the clinician to use appropriate terminology demonstrating awareness and sensitivity to the client. Clinicians ask the client’s names and pronouns for work, at home, and in social situations, to ensure a client’s privacy and safety is protected and the client is not disclosed or “outed.” At present, many insurance forms and data collection forms still have underlying gender binary bias. Familiarity with terminology is an important way of allowing the client to self-identify. Terminology changes, and it varies from person to person; thus, clinicians use it in a manner that is appropriate, respectful, and sensitive. Please see the HRC Glossary of Terms, the PFLAG Glossary of Terms, and ASHA’s resource on supporting and working with transgender and gender-diverse people.
Sensitivity to clients starts at the initial point of contact and continues throughout all interactions. Office support staff and clinicians participate in cultural responsiveness training to increase awareness for working with transgender and gender-nonconforming populations. Cultural responsiveness and accountability are critical to building relationships, maintaining privacy, and creating safe spaces for clients/patients/students.
Nearly one third of respondents of the 2015 U.S. Transgender Survey reported that none of their health care providers knew that they were transgender (James et al., 2016). People may not be comfortable with asking clinicians detailed questions about gender affirming voice. Having openly available and accessible materials about gender affirming voice in the clinical space and on the website may provide the opportunity for individuals to review materials to determine if they wish to pursue services.
Additional adjustments are made to facilities and materials. These modifications include the following:
Inclusive intake and case history forms are necessary for these services. Clients may use more than one name and/or pronoun across a variety of settings, socially, or at work. It is important to ask for the name and pronouns to be used in treatment, with family, during communications and the name to be used if submitting for reimbursement to a third-party payer. If the person does not use the name they were given at birth, clinicians always refer to the client by their chosen name and provide rationale for confirmation of their “dead name” or the name listed on official documentation. The clinician may ask the client/patient/student to verify the name by writing it down and asking for a yes/no verification—saying this “dead name” aloud can be triggering. Provide expansive options in forms regarding pronoun use, honorifics, relationships, and gender to all clients, regardless of the service that they seek, to ensure inclusiveness.
See ASHA’s resource on supporting and working with transgender and gender-diverse people, Self-Reflection: Gender Inclusivity [PDF], Building a Culturally Inclusive & Gender Affirming Space (ASHA On Demand Webinar), and ASHA’s Practice Portal page on Cultural Responsiveness for more information. See also the U.S. Department of Education Toolkit [PDF].
Before verifying benefits or submitting claims to insurance, clinicians ask the client for the identifying information that should be used in communications with their insurance. If a client uses the name assigned at birth with their insurance company, then clinicians may avoid confusion by using initials and eliminating the use of pronouns when writing reports for submission. In documentation and billing, clinicians verify the inclusion or omission of gender, names and pronouns, and which institutions will have access to these documents.
Some people who seek and receive medical services have a diagnosis of gender dysphoria under the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (American Psychiatric Association [APA], 2022) or the International Classification of Diseases and Related Health Problems, 10th Revision, Clinical Modification. It is not in the scope of practice for an SLP to diagnose a client with gender dysphoria. In order to receive the diagnosis of gender dysphoria, one must meet a list of criteria indicated in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (APA, 2022). Coverage varies by payer and plan for services related to gender affirmation. A medical diagnosis of gender dysphoria is often necessary to receive insurance coverage for gender affirming care services but does not guarantee it. However, not all transgender and gender-nonconforming people experience dysphoria or distress from incongruence (APA, 2022).

According to the eighth version of the Standards of Care for the Health of Transgender and Gender Diverse People (Coleman et al., 2022), an SLP with expertise to provide services to transgender and gender-nonconforming people may work on the following areas:
Comprehensive evaluation considers current voice and communication skills to develop a treatment plan in collaboration with the client. Client goals reflect the fluidity needed for their gender expression in all settings. It is also important to refrain from imposing the clinician’s constructs of gender. Some clients may not have goals that reflect the binary constructs of masculine and feminine voice. Focus on the client’s self-determined goals, what they feel fits them, and what best represents their authentic voice. Goals related to voice and communication are specific to each person and may change over time.
Client perspective is critical. A subjective analysis from the client’s perspective, including video and audio recordings, is a component of ongoing assessment that allows for documentation and analysis of progress over time. This may also serve as motivation for the client as measures of success. Self-rating scales are an effective way to gather perspective, set goals, and understand how the client wishes to use their voice (Dacakis et al., 2013, 2017a, 2017b). Questionnaires can also be helpful tools during assessment to understand voice-related experiences. There is often a discrepancy between a client’s and a clinician’s perception of vocal parameters. The client may have a hypercritical self-perception and may express frustrations about their progress (Azul et al., 2018).
Intake forms and client interviews gather the following information to develop a person-centered plan of care:
Transgender and gender-nonconforming clients may undergo a variety of medical, surgical, physical, social, and personal procedures—as well as legal procedures—to increase the congruence between their gender and their presentation. Not all of these procedures will directly impact communication. SLPs obtain information only to determine the possible influence on the voice and voice mechanism (Hancock et al., 2017). For instance, the use of chest binders, to form a more masculine chest, may impact respiration and phonation (Block et al., 2019). In addition, there are surgical options (Davies et al., 2015) that may alter the structure of the vocal folds and/or the larynx and that could possibly impact vocal pitch, loudness, quality, and resonance and/or swallowing. Surgery can influence oral, laryngeal, and pharyngeal structures and mechanisms, as well as the ability to consistently maintain practice during the rehabilitation process. These surgeries can include facial feminization/masculinization, chest or breast reconstruction, laryngeal surgery and surgical modifications of the face and neck, electrolysis/laser hair removal, and so forth.
Some—but not all—people might receive genital gender affirmation surgery. However, this gender affirmation procedure does not influence the voice. Therefore, asking such questions on a standard intake form and/or during initial intake is not relevant and is often considered an invasion of privacy for service delivery. The SLP is aware of medical and nonmedical factors that influence the continuum of care (see Social Determinants of Health) and coordinates service delivery with an interprofessional team to ensure smooth and effective delivery of coordinated services. It is also essential to have thorough knowledge of any existing disorder, condition, or prior intervention to ensure the best course of treatment.
Assessment tools developed specifically for gender affirming voice training are typically client self-report measures that examine the wide range of potential needs among transgender and gender diverse people seeking gender affirming voice and communication training. While these questionnaires can provide valuable information for gender affirming voice and communication training, medically oriented voice questionnaires, such as the Voice Handicap Index, may be needed to assess experiences when there are vocal pathology symptoms (Shefcik & Tsai, 2021). However, self-rating scales of vocal health tailored to the transgender and gender diverse populations may be more accurate, as they separate out whether vocal concerns are indicative of the speakers’ vocal health or self-perceptions of voice congruence (Hancock et al., 2017).
Following the client’s lead is critical for setting needs and goals because gender and communication needs are unique to each person. The ultimate goal is to assist the client in achieving an authentic voice and communication style based on their needs while protecting their voice mechanism. Modifying voice without proper guidance can encourage maladaptive patterns of voice misuse, leading to phonatory trauma and voice disorders such as muscle tension dysphonia and vocal nodules (Hillman et al., 1989; Karkos & McCormick, 2009).
Gender affirming voice therapy may not be available to all ages depending on state law and may require additional and unique considerations (Hirsch et al., 2019). See WPATH’s Standards of Care for the Health of Transgender and Gender Diverse People, Version 8 for additional information on working with transgender and gender-nonconforming people of different ages. See ASHA’s resource on gender affirming voice therapy advocacy for specific state information.
Gender affirming voice and communication therapy focuses on a combination of characteristics, including pitch, resonance, speech, and nonverbal communication, to better align gender and gender expression (Hancock & Garabedian, 2013). Clinicians might incorporate aspects of intervention strategies traditionally used with functional voice and resonance disorders but modify the strategies to meet the client’s goals. For example, the clinician may have their client use vocal function exercises to safely shift the vocal pitch range. Strategies specific to working with voice modification for transgender and gender diverse clients include the following:
See ASHA’s Practice Portal pages on Voice Disorders and Resonance Disorders or ASHA’s On Demand Webinar Transgender Voice and Beyond: Voice and Communication Training for Gender Expression for more information.
Affirming goals focus on creating a voice that is authentic, comfortable, and safe (Hancock, 2015). Some people prefer a “gender-neutral” vocal presentation, whereas some people require flexibility for a more masculine or feminine presentation, depending on social or work environments. For these clients, vocal flexibility may rise to the top of the list of treatment goals. A speaking fundamental frequency (SFF) higher than 180 Hz is more likely to be perceived as feminine, whereas any fundamental frequency (F0) lower than 130 Hz is more likely to be perceived as masculine (Leung et al., 2018), and an androgynous, or gender neutral, SFF ranges from 145 Hz to 175 Hz (Davies et al., 2015). Practitioners are encouraged to avoid an overemphasis on SFF and to focus on client-specific concerns when approximating a more gender affirming voice configuration.
The client’s self-determined voice modification goals are set in the beginning based on how they would like to express their voice sex (i.e., male, female, androgynous) or voice gender (i.e., masculine, feminine, gender neutral). Some people may aim to increase SFF and/or moving resonance forward (Carew et al., 2007; Gelfer & Mikos, 2005; Hirsch, 2017; Leyns et al., 2023). SFF, average formant frequency, and sound pressure level can be predictors of the listener’s perception of the speaker’s gender (e.g., Hardy et al., 2020). Additional voice features, such as intonation, resonance, and loudness, may help the client reach their voice goals. Historically in the literature, femininity associated with voice is somewhat greater with softer volume, more precise articulation, and more variable intonation. Rate of speech and stress do not appear to be associated with gender perception (Leung et al., 2018). However, these standards for “voice feminization” rely on gender binary norms and may not represent the goals of transgender women, nonbinary clients, or transfeminine clients (Goldberg & Kapila, 2023). Cisgender women’s voices feature a diverse range of pitch, resonance, and vocal tract configurations; therefore, there is no single definition for voice feminization (Goldberg & Kapila, 2023). While research may reference these terms, consider moving away from binary labels in consultation with clients, such as asking for examples of voices they would like their voice to sound like, to set appropriate goals and to determine which acoustic and auditory perceptual markers are tracked for progress (Goldberg & Kapila, 2023).
Not all people seeking “voice masculinization” require hormone therapy to do so. Clinicians might use behavioral voice approaches, such as modified vocal function exercises (e.g., Myers & Bell, 2020) and circumlaryngeal massage and laryngeal reposturing (e.g., Dahl et al., 2022), to help their clients achieve a perceived lower pitch. Voice masculinization may also focus on adopting chest resonance and reducing pitch variation (Schneider & Courey, 2016).
A common misperception is that androgen cross-sex hormones often result in the lowering of pitch, which eliminates the need for voice treatment (Azul et al., 2018; Nygren et al., 2016). However, the extent, rate, and experience of using hormone therapy alone are quite variable and not always satisfactory (Irwig et al., 2017; Ziegler et al., 2017). Hormone therapy increases testosterone levels, adding mass to the vocal folds and, typically, lowering the pitch in varying degrees. Hormone treatment does not result in changes to other aspects of voice (e.g., intonation, volume, and nonverbal communication) that may influence how gender is perceived by others. For example, some transmasculine speakers receiving hormone therapy might feel uncomfortable with using a lower pitch, so they use a higher habitual speaking pitch than their new lower pitch range physiologically allows (Papp, 2011).
The following areas can influence gender perception:
However, clinicians note that variability in how these are perceived exists within cultures and across cultures. For example, appropriate distance when speaking varies across gender and across cultures. Clinicians also consider that clients may have additional underrepresented and marginalized identities that shape their unique experiences. These intersecting identities influence the clients’ goals, understanding of available services, access to services, self-acceptance, and acceptance by the people around them (Hancock & Downs, 2021). Do not assume the areas of communication a client will want to work on. Working together to establish goals for how the client wishes to express their gender is essential to establishing a patient-centered plan of care. See ASHA’s Practice Portal page on Cultural Responsiveness.
Timelines for reaching goals and outcomes may be influenced by the client’s age, frequency of treatment, other gender-related interventions, and overall time available to practice using their authentic voice. Clients may be able to choose the frequency of treatment that works best for their lifestyle (Quinn et al., 2022).
Various factors influence the ability to present as the client’s authentic gender in all settings. Goals and needs may also change as the client’s self-expression and gender identity evolve (Smith, 2020). It can be challenging to allow for a time or place to practice. The clinician can incorporate opportunities for practice into individual and group sessions and monitor changes with audio and video recordings. To enhance carryover in connected speech and generalization to voice use in everyday activities, clinicians may use a variety of options, including video chatting, talking on the phone, and meeting at another location such as at a restaurant or coffeehouse. These activities allow for opportunities to work in realistic scenarios. When developing a treatment plan with a person seeking gender affirming voice services, the clinician considers the potential challenges of introducing, incorporating, and maintaining the new voice and communication style in daily life.
Group intervention provides an opportunity for clients to practice carryover in a supportive social situation. Clinicians facilitate the group norms and overall goals, whereas each participant can work toward their own personal goals. Groups provide a safe opportunity to receive feedback and celebrate success toward goals (Kayajian et al., 2019). This may be particularly important for people who do not have the opportunity to practice their skills outside of the clinic environment. People may enjoy reaching their specific voice and communication goals with peer support, which encourages consistency, confidence, and self-esteem (Merrick et al., 2022; Pickering & Kayajian, 2014).
SLPs help the client transition to a new voice and to a new way of communicating and hearing themselves differently. Clinicians may find themselves working with clients in various emotional states connected to their voice—ranging from frustration, grief, and anger to acceptance and enthusiasm. Discrimination, stigma, and/or violence toward the transgender and gender-nonconforming community can also negatively impact psychosocial well-being (White Hughto et al., 2015). SLPs are not trained mental health service providers; however, they may find themselves in positions where it may be beneficial to have familiarity with skills and strategies used by trained mental health service providers (Adler & Pickering, 2019). It is within the SLP’s roles and responsibilities to provide counseling that facilitates change in how clients feel and think about and their communication. In addition to the SLP supporting clients’ well-being, clients may seek the assistance of mental health providers for support during transition. Mental health providers are collaborative partners to the SLP. Some issues may arise during treatment that pertain to adjusting to the mind–body–spirit connection. Some clients may experience distress; some will not.
All communities are diverse, including gender diverse communities. Each client may require different individualized approaches because their journeys are all unique (Adler, 2017). Transgender and gender diverse clients come to clinicians with different needs, expectations, and experiences, including the experiences of intersecting identities (Hancock & Downs, 2021). Clinicians may benefit from gaining additional knowledge and skills in counseling that are specific to transgender populations.
See ASHA’s Practice Portal pages on Counseling in Audiology and Speech-Language Pathology and Cultural Responsiveness. See ASHA’s resource on trauma-informed care.
Telepractice can be a viable way to provide services if it fits with the client’s lifestyle and if they have access to the appropriate equipment (Myers et al., 2022). Virtual visits, as an alternative to or in conjunction with in-person visits, may encourage clients to continue voice therapy (McKenna et al., 2023).
Various mobile and web-based apps—in conjunction with voice treatment—may assist with generalization and carryover. Cell phones and tablets have audio and video capabilities that make technology a natural resource for home practice. Some web-based tools have been developed specifically for trans speakers, but some others are pitch-tuning apps (e.g., apps for piano playing, guitar tuning, etc.). Clinicians who are familiar with the technology can educate their clients on using it as part of their home program to avoid inappropriate practice, which can contradict treatment efforts and lead to the development of hyperfunctional voicing patterns.
Ethical considerations for SLPs include provision of services under the scope of the expertise.
The Code of Ethics (ASHA, 2023) and the Issues in Ethics Statement on Cultural and Linguistic Competence (ASHA, 2017) further clarify principles pertaining to gender identification.
Principle of Ethics I: Individuals shall honor their responsibility to hold paramount the welfare of persons they serve professionally or who are participants in research and scholarly activities.
Rule A. Individuals shall provide all clinical services and scientific activities competently.
Rule B. Individuals shall use every resource, including referral and/or interprofessional collaboration when appropriate, to ensure that quality service is provided.
If a professional feels unqualified to serve a person, they should make the appropriate referral. The clinical protocol for gender affirmation services is built from skill sets developed from working in the area of voice—including pitch, resonance, intonation, articulation, language, and nonverbal communication; however, additional knowledge and training for sensitivity are essential to working with transgender and gender-nonconforming populations.
Rule C. Individuals shall not discriminate in the delivery of professional services or in the conduct of research and scholarly activities on the basis of age; citizenship; disability; ethnicity; gender; gender expression; gender identity; genetic information; national origin, including culture, language, dialect, and accent; race; religion; sex; sexual orientation; or veteran status.
SLPs are uniquely qualified to provide gender affirming voice therapy. However, not all clinicians are qualified to provide gender affirming voice therapy nor are they required to do so. However, clinicians may not refuse services for which they are qualified based on a person’s gender, gender identity, or gender expression.
Principle of Ethics II: Individuals shall honor their responsibility to achieve and maintain the highest level of professional competence and performance.
Rule A. Individuals who hold the Certificate of Clinical Competence shall engage in only those aspects of the professions that are within the scope of their professional practice and competence, considering their certification status, education, training, and experience.
SLPs who serve this population should be specifically educated and appropriately trained to do so.
See ASHA’s Code of Ethics, Prohibitions Against Discrimination Under ASHA’s Code of Ethics and Enforcement by the Board of Ethics, Issues in Ethics: Cultural and Linguistic Competence, and Supporting and Working With Transgender and Gender-Diverse People.
Legislation and regulations related to gender identity and treatment are constantly evolving. Although there are federal protections for transgender and gender-nonconforming people, these are dependent on the interpretation of a given presidential Administration. Once an Administration changes, these guardrails can be easily reinterpreted or eliminated. State laws and regulations will vary. See ASHA’s resource on gender affirming voice therapy advocacy for additional information about specific regulations. For information on health insurance coverage, see Payment of Gender-Affirming Voice Therapy.
Seek legal counsel if you have questions or concerns regarding the impact of federal or state law.
This list of resources is not exhaustive, and the inclusion of any specific resource does not imply endorsement from ASHA.
