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.
