One of the things that seems limiting with this version is that, when the words existed (like "wife" and "dogs"), it just seemed to copy-and-paste them around.

One of the things that seems limiting with this version is that, when the words existed (like "wife" and "dogs"), it just seemed to copy-and-paste them around. That honestly sounded pretty bad. But the new words sounded better. I think that if they were using some of the AI-based libraries for generating speech, like WaveNet[1] (hear the samples towards the bottom), and then layered on-top the learning that this algorithm did to get it to sound like the speaker, you'd have a pretty powerful system that would be able to get the intonation right much of the time. And then, of course, when you have the Pro version, you're presumably be able to add additional markup to specify intonation even further. 1. https://deepmind.com/blog/wavenet-generative-model-raw-audio/ https://deepmind.com/blog/wavenet-generative-model-raw-audio...
