If you are a frequent user of voice input with Google Search, you may be noticing a change in the voice of Google’s assistant that reports results back to you. The U.S. English female voice that has been used for several years is being retired with a new voice that is smoother and sounds more natural.
Below is a video that highlights the differences between the old voice and the new voice. You should be able to tell that the new voice has a more natural intonation and the answers sound more fluid and not as disjointed.
Currently there are no pending updates to the Google Search app or the Google Text-to-Speech app available in the Play Store. Thus, it appears this change is being made on the server-side. The change to the voice comes as Google faces some competition in the personal assistant space on Android devices, notably from Microsoft’s Cortana, which generally receives good marks for usability.
