It said on its official blog that with the new machine learning approach, NTTS will deliver “significant improvements in speech quality.” The 2 things it increases are naturalness & expressiveness. Both, said Amazon, were key to synthesizing lifelike speech that is getting closer than ever from human voices.
As of today, NTTS will be available for 11 voices, both in real-time & in batch mode:
- All 3 UK English voices
- All 8 US English voices
Introducing the newscaster style
Speech quality is certainly important, but more can be done to make a synthetic voice sound even more realistic & engaging. What about style?
For sure, human ears can tell the difference between a newscast, a sportscast, a university class & so on; indeed, most humans adopt the right style of speech for the right context, & this certainly helps in getting their message across.
With this new feature, from news to blog posts, narration will sound even more realistic, said Amazon.
