Google text to speech powers applications to read the text on your screen aloud. For example, it can be used by: • Google Play Books to 'Read Aloud' your favourite book • Google Translate to speak translations aloud so that you can hear the pronunciation of a word • TalkBack and accessibility applications for spoken feedback across your device • … and many other applications in Play Store
To use Google text to speech on your Android device, go to Settings > Language & Input > Text to speech output. Select Google text to speech Engine as your preferred engine. Note: On many Android devices, Google text to speech is already turned on, but you can update to the latest version here.
