If you’ve performed any voice searches lately, you may have noticed the Google app responding with a more natural, less robotic sounding voice. It’s not just you. Google recently updated the voice they use for text-to-speech and the results are amazing. If you’ve ever wondered what goes into building great sounding speech synthesis, Nat and Lo are once again taking you behind the scenes at Google in their latest video.

This time around, the pair of Googlers are interviewing the team at Google responsible for creating the new voice of the Google app. There’s a voice coach, a linguist, and finally the talent (who sadly, wouldn’t show her face on camera) who record a combination of phrases and store them in a database. Once they’re done, they splice together chunks of recordings and speech patterns to create more natural sounding speech, something anyone who’s recently used the Google app has probably noticed.

Given how complicated language is, there’s a lot that goes into making a computer voice sound more natural and if you’re curious to see what goes into recording the new Google app’s voice, check out Nat and Lo’s video above. For a quick look at what the new Google app’s voice sounds like in practice, Nat and Lo’s have a bonus video that demos 15 different voice searches. Cheers.
