I started building a proof of concept for Polly sounds for English. I thought that Matthew neural version sounded pretty good, and we don't have a Male voice (just 3x female voices).

https://github.com/avimar/freeswitch-sounds-polly

I don't have it automated to generate a whole set, but there's a bunch of samples.

Also, can someone please chime in on downsampling... I assume we want direct PCM but that's only available up to 16000. (And you need to add a header to make it a normal readable wav)

Mp3 an ogg are available at 24000. Not sure what the best way to get our samples are, I used sox and got a bunch of versions -- 8000 pcm direct from amazon, 16000, 16000 downsampled from the ogg....

I also haven't tested mod_say for numbers and currencies to see how it sounds... probably need to do something to make it flow better.

I'm going to try and put together a sounds set from the freeswitch phrase file and will submit back to project.

In my case, even if the word-to-word transitions are not as uniform as callie, it will allow my custom prompts to have
the same voice as the system prompts.
