Add google text-to-speech support #1
Description
Many "neural" voices, they call it wavenet. Same low pricing.
Returns native LINEAR16 - Uncompressed 16-bit signed little-endian samples (Linear PCM). Audio content returned as LINEAR16 also contains a WAV header.
I'm not sure where to find the native hertz rate per voice, to know if 48000 hz is supported.
Not sure if it's allowed for re-use. I asked here: https://stackoverflow.com/questions/61609222/can-i-distribute-googles-text-to-speech-files
