As part of Google's ongoing effort to spin off certain software features into Google Play for easier updating, the company has today launched the Google Text-to-Speech engine as a standalone app on the Play Store. The will push out automatically to those using an older version (not you, Nexus 5 owners, you're already up-to-date out of the box). If you install it on a device that doesn't have it already, it'll appear as an option alongside whichever manufacturer-loaded text-to-speech service is currently in use.
The only major change we're seeing compared to the older pre-loaded version is the addition of Korean as a supported language. However the ability to update text-to-speech without requiring an OS upgrade presents the possibility of Google introducing more advanced TTS features through future app updates.
