How do you change your voice from male to female on the call app?

Voice feminization refers to the process of adjusting one’s vocal pitch and vocal characteristics to sound more feminine. Voice feminization is commonly pursued by transgender women as part of their gender transition, in order to have their voice match their gender identity and expression. For many transgender women, having a feminine-sounding voice is an important part of alleviating gender dysphoria and being perceived as female in social interactions.

There are a variety of reasons why transgender women and others may seek to feminize their voices. A higher-pitched, feminine voice can help transgender women pass or be correctly gendered as female in situations where visual gender cues are absent, like on the phone. It can also help reduce misgendering in face-to-face interactions. Additionally, having a voice that aligns with one’s gender identity can greatly improve self-confidence and self-image.

Background on Voice Pitch

Voice pitch is determined by the length and thickness of one’s vocal cords. Men generally have longer and thicker vocal cords compared to women, which results in a naturally lower-pitched voice. The difference in vocal cord size is a result of hormonal differences, particularly testosterone levels. Puberty causes an enlargement of the larynx and vocal cords in boys, triggered by increased testosterone production. This elongation of the vocal cords creates a lower fundamental frequency of vibration and thus a deeper voice pitch.

According to research, the average fundamental frequency of an adult male voice is around 120 Hz while the average female voice pitch is around 210 Hz. However, there is natural variation even among those of the same sex. Some women naturally have lower-pitched voices closer to 165 Hz, while some men have higher voices around 150 Hz. Genetics, body size, vocal training, and other factors contribute to these individual differences in vocal pitch.

In summary, the lower voice pitch in males is an anatomical difference caused by testosterone exposure. While there are individual variations, men on average speak in a lower vocal range than women due to having larger and thicker vocal cords.


Changing Voice Pitch

There are several techniques available for changing your voice pitch, both temporarily and permanently:

Voice Training Exercises

Doing vocal exercises can help strengthen and develop your voice over time. Some examples include:

  • Humming and lip trills to relax the vocal cords.
  • Practicing speaking in a higher or lower pitch.
  • Working on vocal range by singing scales and songs.
  • Controlling breathing for proper voice support.

With consistent practice and training, these exercises may allow you to gradually change your habitual speaking pitch (source). However, it takes time and dedication.


There are some surgical options like vocal cord surgery or voice feminization surgery that can help permanently raise or lower pitch. However, these carry risks and should only be considered after exhausting nonsurgical options (source).

Apps and Devices

There are also apps and devices that can modify your voice pitch in real-time. These provide a temporary change, but the effects go away after you stop using them.

Voice Training Exercises

There are various exercises that can help train your voice to sound more feminine and raise your pitch. Some common exercises include:

  • Holding a note at the top of your range for as long as possible. This helps strengthen and extend your vocal range.
  • Glissando slides up and down your range. Start low and slide up in pitch, then reverse back down. This increases flexibility.
  • Lip trills are quick trills done by vibrating your lips while phonating. This raises pitch and develops head voice.
  • Tongue trills create a rolling or fluttering sound. This helps thin vocal folds to raise pitch.
  • Head voice sirens start low and swing up and down using your head voice. This stretches your range.
  • Speaking in a breathy whisper helps develop your head voice to carry into normal speech.

Consistency is key with vocal exercises. Aim for 5-10 minutes per day, focusing on proper breathing, posture, and resonance technique. Over time, these exercises will allow you to speak in a higher feminine pitch.

Surgical Options

One option for changing voice pitch from male to female is through surgical procedures like feminization laryngoplasty or cricothyroid approximation. As described in the source article from Cleveland Clinic, Feminization Laryngoplasty, this type of surgery involves shortening and tightening the vocal cords to raise vocal pitch. It is estimated that about 1% of transgender women have opted for surgical voice feminization procedures.

As explained in the patient story from Cleveland Clinic, Jacqueline Griffiths: Vocal Therapy Patient Story, while some patients decide on surgery, others prefer non-surgical options like vocal therapy. The choice depends on personal preferences, finances, and health considerations. Surgical procedures carry risks and require recovery time.

In summary, feminization laryngoplasty is one surgical option for transgender women seeking to permanently raise vocal pitch, but it may not be the right choice for every individual. Thorough research, consultation with doctors, and consideration of alternatives is advised.

Apps and Devices

There are various apps and devices available to help alter and feminize voice pitch. Some popular apps include Christella VoiceUp, Voice Analyst, Voice Thickness Meter, and Pitch Tracker. Christella VoiceUp provides over 2 hours of voice feminization lessons and exercises through a comprehensive course, with the goal of achieving a passable feminine voice with just 10 minutes of daily practice.

Other apps like Voice Pitch Analyzer allow you to easily track and monitor changes in your voice pitch over time during vocal training. This can help you visualize your progress and ensure your voice pitch is increasing into the typical female range. Apps like Voice Analyst also give real-time feedback on your resonance, intonation, loudness variability, and other vocal parameters.

Specialized devices can also assist with voice feminization. These include voice changers or voice modulators that shift the pitch and adjust other qualities of your voice input in real-time. However, apps and devices alone cannot achieve a complete vocal transition – this requires ongoing voice therapy and training. But they can be useful tools to complement these efforts.

Using Voice Changing Apps

There are many voice changing apps available for both iOS and Android that can modify your voice during phone and video calls. Some of the most popular options include Voice Changer Plus, VoiceUp, Voicemod, and Clownfish. Here is a step-by-step guide to using these apps on your mobile device:

1. Download and install the voice changing app from the App Store or Google Play Store. VoiceUp and Clownfish have free versions available.

2. Open the app and browse the different voice effects. Apps like Voice Changer Plus and Voicemod have many options like baby, robot, alien, echo, and more. VoiceUp and Clownfish have more basic effects like male/female pitch shifting.

3. Select your desired voice effect. You can usually adjust the pitch, tone, echo and other parameters to customize the sound.

4. Make a test call to a friend or use the app’s ‘Hear Myself’ feature to preview how your voice will sound with the effect applied. Adjust the settings until you’re happy with the result.

5. When ready, open your phone’s calling or video chat app and start a call. Your voice will now sound modified to the other caller based on the voice effect settings.

6. For best results, use headphones with a microphone while making voice calls with the effects enabled. This prevents echo or feedback.

7. Remember to turn off or exit the voice changer app after your call to return your voice to normal.

Tips and Best Practices

With regular practice and dedication, you can learn to feminize your voice over time. Here are some helpful tips and best practices to get started:

Focus on speaking from your head rather than your chest. Try to raise the resonance of your voice up into your facial muscles and sinus cavity (Source 1).

Work on hitting a higher overall vocal pitch, around 160-220 Hz for the average female range. Use a voice pitch analyzer app to track your progress (Source 2).

Practice speaking with breathiness and smooth vocal inflections. Concentrate on keeping an even, feminine tone.

Record your voice frequently and listen back objectively. Identify areas needing improvement and keep practicing until your voice sounds natural.

Join online communities or forums for mtf voice feminization support and tips. Watch video tutorials from voice coaches.

Consider professional voice therapy or training tailored to mtf needs. This can help ingrain new speech patterns.

Be patient and keep working at it. Reaching your feminine voice goals takes diligent practice over time. But staying motivated will make a difference.

Challenges and Limitations

Changing your voice from male to female can be challenging for several reasons. Many transgender women find voice training difficult and it can take a lot of practice to make lasting changes (Princess Riley, 2023). It requires developing new speech habits and finding your feminine voice. Some of the key challenges include:

Pitch range – Increasing pitch alone does not guarantee a feminine voice. You need to expand your vocal range and speak using a variety of pitches. This takes time and dedication.

Resonation – Learning to project sound through your mouth instead of your chest requires adjusting your resonators. This can feel unnatural at first.

Inflection – Adopting feminine speech patterns like more expressive inflections takes conscious effort. It may not come naturally.

Consistency – Maintaining your feminine voice consistently can be tiring. It takes a lot of practice before it becomes second nature.

Confidence – Feeling confident using your new voice can be challenging. Self-consciousness may undermine your progress.

Apps and devices – While technology can help, it has limitations. Over-reliance on apps can hinder developing full vocal range.

Surgery – Though effective for some, vocal surgery is expensive, invasive, and not easily reversible. It may not produce the exact results you want.

Patience and dedication are needed to overcome these challenges. It takes time to find your feminine voice. But with practice, it is possible to gain confidence and consistency. Be kind to yourself through the process.
