Support Mozilla TTS engine

[lyz-code]

Hi, Mozilla TTS sounds awesome, and I think it would be a good engine addition to talkey.

That's actually very interesting. The inverse of their DeepSpeech dataset? I didn't know it exists.

Sorry, I liked the STT, here is their TTS, they are both based on the Common Voice datasets

I have to say, that voice is a really good quality. Installation is huge, but not difficult. It seems like using it as a HTTP service would be easiest?

I wasn't aware that they had their HTTP service (if I understood you well). I would personally prefer to self host it for privacy concerns, but I can see why the regular user would prefer not to install things and rely on existent services.

If supporting both options is not much work, that would be awesome :)

When you install it you have the tts library which takes a long time to startup, and tts-server service which provides an http api.

It's self hosted in both cases.

Either would work, but deploying the service on a more powerful server would give faster speech results, for example.

I see, then the HTTP API server suits my case perfectly.
