[Freeswitch-users] FYI - new Amazon Web Services TTS option

[Avi Marcus]

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.
