Google is taking further steps to reach one of their newer venture's goal, in providing app integration software with the release of an Android Auto API. With this in mind app developers have started adapting and tweaking their apps and some including Google Text to Speech. Looking at the 2015 Hyundai Sonata the API supports two categories of apps but many third party app developers are getting involved with the apps. In relation to Google Text to Speech this evolution has helped advance uses of the app, with other apps such as textPlus and WhatsApp displaying text on a screen normally instead in the car the text was read aloud by Google's Text to Speech. Thus giving the driver more freedom and flexibility and they are given the option to reply via voice without even removing their hands from the steering wheel.
The implications of Google text-to-speech are expanding. Google Chrome extension Chrome Speak can read aloud any selected piece of text within the browser. Chrome Speak uses the default text-to-speech feature of the operating system (Mac OS X, Windows and Chrome OS) and the user can listen to text read aloud from the computer. To run the Chrome Speak application Google Chrome browser is required.
Speak It is another extension of Google text-to-speech products, which is similar to Chrome Speak. Speak It reads out loud selected text within Google Chrome browser, but is considered a low-quality text-to-speech application.
