What "changing your voice" means and where you can do it
Changing your voice usually means one of three things: adjusting how your device reads text aloud to you, swapping the voice used by a voice assistant like Siri or Google Assistant, or using an app to alter how you sound in calls or recordings. The steps differ depending on which device you use and what you're trying to do.
Most phones and computers come with multiple built-in voices you can switch between without downloading anything. Some let you adjust speed and pitch. Apps that modify your voice during calls or recordings are separate downloads and work differently on each platform.
This guide covers the main routes: changing text-to-speech voices on phones and computers, swapping voice assistant voices, and using voice-changing apps for calls and recordings.
Key Takeaways
- Your phone or computer likely has multiple text-to-speech voices built in; you can switch between them in settings without installing anything new.
- Voice assistants like Siri, Google Assistant, and Alexa each have their own voice-switching menus, usually found in the assistant's settings or preferences.
- Voice-changing apps for calls and recordings are third-party downloads that work differently on iPhone, Android, Windows, and Mac.
- Text-to-speech speed and pitch can usually be adjusted in the same menu where you pick the voice.
- Some voices are available only on certain devices or require an internet connection to work.
Changing text-to-speech voices on iPhone and iPad
On iPhone and iPad, text-to-speech voices live in Settings under Accessibility. Open Settings, tap Accessibility, then select Spoken Content. You'll see options for Voices, Speaking Rate, and Speaking Pitch.
Tap Voices to see what's available. Apple includes several English voices by default, and you can download additional ones. Each voice shows which language it supports and how much storage it uses. Select the one you want, and it becomes your default for any app that reads text aloud.
If you want to hear a voice before committing, tap the play button next to it. You can adjust the speaking rate with a slider — slower for easier listening, faster to move through text quicker. Pitch works the same way.
Changing text-to-speech voices on Android
Android stores text-to-speech settings in a different place depending on your phone's manufacturer, but the path is usually Settings > Accessibility > Text-to-Speech Output. Tap Preferred Engine to see what's installed — most phones come with Google Text-to-Speech.
Tap the settings icon next to your preferred engine to open its options. You'll find a Voices menu where you can pick your language and voice. Google offers several voices per language, and you can preview each one before selecting it.
In the same menu, look for Speech Rate (speed) and Pitch sliders. Some Android phones also let you download additional voices, though this varies by manufacturer.
Changing your voice assistant on phones and smart speakers
Siri, Google Assistant, and Alexa each have their own voice-switching process. On iPhone, open Settings, tap Siri & Search, then Siri Voice. You'll see options for different accents and genders within English, plus other languages. Pick one and it takes effect immediately.
On Android with Google Assistant, open the Google Assistant app, tap your profile picture in the top right, go to Settings > Assistant Voice and Style, and choose from the available voices. You can preview each before selecting.
For Alexa on Echo devices, open the Alexa app on your phone, tap More (the three lines), go to Settings > Device Settings, select your Echo device, then tap Alexa's Voice. Amazon offers a smaller selection than Apple or Google, usually two or three options per language.
Changing your voice on Windows and Mac
Windows 11 stores text-to-speech voices in Settings > Accessibility > Text Size and Style, then Text-to-Speech. Click the dropdown under Voice to see what's installed. Windows comes with several voices by default, and you can download more from the Microsoft Store.
You can adjust speaking rate and pitch in the same menu. Click the preview button to hear a sample before you commit to a voice.
On Mac, go to System Settings > Accessibility > Spoken Content. Click the dropdown under System Voice to pick from available options. Mac includes voices in multiple languages and accents. You can adjust speaking rate with a slider. Preview any voice by clicking the play button next to it.
Using voice-changing apps for calls and recordings
If you want to alter how your voice sounds during a phone call or while recording audio, you'll need a third-party app. These work differently on each platform and have different limitations.
On iPhone, options are limited because Apple restricts how apps can access the microphone. Apps like MorphVOX Junior and Voice Changer can record audio and apply effects, but they don't work during regular phone calls — only in apps that let you record or send voice messages.
On Android, apps like Voice Changer and Voicemod offer more flexibility. Some can intercept your microphone during calls in certain apps, though this depends on the app you're calling through and your phone's permissions.
On Windows and Mac, Voicemod is the most widely used voice-changing software. It works as a virtual microphone, so any app that uses your microphone — including video calls, streaming, or recording software — can use the altered voice. Download it, install it, pick a voice effect, and select Voicemod as your microphone in your app's audio settings.
Downloading additional voices and language packs
Most devices let you download extra voices beyond what comes pre-installed. On iPhone, go to Settings > Accessibility > Spoken Content > Voices and look for a download icon next to voices you don't have yet. On Android, the process varies by phone, but usually involves tapping a download button in the text-to-speech settings.
Windows and Mac both let you download voices from their respective app stores. On Windows, go to Settings > Accessibility > Text-to-Speech and click Add Voices. On Mac, go to System Settings > Accessibility > Spoken Content and click the dropdown to see download options.
Downloaded voices sometimes require an internet connection the first time you use them, but most work offline after that. Check how much storage each voice uses before downloading if your device is running low on space.
Frequently Asked Questions
Can I change my voice on a specific app only, not system-wide?
Most apps use your device's default text-to-speech voice, so changing it system-wide affects all apps. Some apps like Kindle or Google Play Books have their own voice settings that override the system default. Check the app's settings menu to see if it offers voice options separate from your device settings.
Why does my device only have one voice available?
Your device may have only one voice installed by default, but others are usually available to download. Go to your text-to-speech settings and look for a download or add button next to the voice list. If nothing appears, your device may not support additional voices, or you may need to connect to the internet to see what's available.
Do voice-changing apps work on all video call apps?
Voice-changing apps work on some video call apps but not all. On Windows and Mac, Voicemod works with most apps because it acts as a virtual microphone. On iPhone and Android, compatibility depends on the app and how it handles microphone access. Test the voice-changing app with your video call app before an important call to make sure it works.
Can I use a downloaded voice offline?
Most downloaded voices work offline after the first download, but some require an internet connection every time you use them. Check your device's text-to-speech settings to see which voices are marked as online-only. If you need offline voices, stick with the ones that come pre-installed or download ones that don't require a connection.
What's the difference between pitch and speaking rate?
Speaking rate controls how fast or slow the voice reads — useful if you want to move through text quickly or need more time to understand it. Pitch controls how high or low the voice sounds. Adjusting pitch doesn't change speed, just the tone of the voice.
