Adjust VoiceOver voices
Enhanced-quality voices can be 100 MB or larger. Connect your device to Wi-Fi to download and install one of these voices.
Converting text to speech is very full-featured, but the built-in speech recognition system is much more limited. You can work with the built-in services in some cases, but you may need a more full-fledged dictation software. To use voice dictation in an application on your Mac, first select a text field in an application. Next, press the Fn (Function) key twice or click the Edit menu and select Start Dictation. Speak to your Mac and the words you speak will start appearing in the text field.
To change the voice of the reader in Mac, please go to System Preferences > Dictation & Speech > Text to Speech. You can change the system voice as well as the speaking rate. You can also test the voice to make sure you like it by pressing “Play” in System Preferences.
With VoiceOver, you can turn on more than one voice, switch between Default and Enhanced Quality (without needing to download the voice again), and change the speaking rate for each voice. To adjust the voices:
- Go to Settings > General > Accessibility > VoiceOver and tap Speech.
- Tap Add New Language.
- Tap the language and dialect that you want. This will take you back to the Speech screen.
