Google researchers have found ways to make machine-generated speech sound more natural to humans, members of Google’s Brain and Machine Perception teams said today in a blog post that included samples of the more expressive voices. Earlier today, Google announced the beta release of its Cloud Text-to-Speech services to provide customers with the same speech synthesis used by Google Assistant. Google’s Cloud Text-to-Speech is powered by DeepMind’s WaveNet, which can also be used to generate natural-sounding voices.
