To hear the the most life-like simulated speech, if using an Apple iPad or iPhone, it us usually worth using one of the Enhanced voices that you can easily download to your device from Apple (free of charge), rather than the basic voice or voices that came with the device. You can download and choose between available voices using the device's Settings. At iOS 13 or later, go to Settings > Accessibility > Spoken Content > Voices. The equivalent location in older versions is Settings > General > Accessibility > Speech > Voices.
Watch the video below to find out how to select different voices on iOS, and hear what they sound like when used in our apps.
If multiple simulated voices are available on iOS, the app will normally use whichever you have selected as the device's default for your language. However, if you have selected a language-voice combination with a particular gender for a profile or a collection in those of our apps that offer this choice, the app will will preferentially select a male or female voice accordingly.
On Android, you can install voices, and in some cases select gender, from Language and input > Text-to-speech output, in the device's Settings.
In our previous blog, we shared videos showing you how to enable and use the text to speech feature in Special Words and Special Stories on iPad.
