GoogleNetworkSpeechSynthesis VS TTS

If you want you can use Google's TTS service without Web Speech API with a proxy, see GoogleNetworkSpeechSynthesis. I made a feature request for Google to release the source code as FOSS Re: Issue 263510047: Release TTS and STT source code and Google voices as FOSS so we don't have to make external requests just to use Web Speech API.

I requested to Google to Release TTS and STT source code and Google voices as FOSS which you can request over the network here GoogleNetworkSpeechSynthesis. Those are the voices Google Chrome uses for Web Speech API. Feel free to chime on the feature request in in support of Google releasing the source code of its network-based cloud service (that google uses for Web Speech API implementation) TTS and SST code as FOSS.

Technically you can use Google API key shipped in the browser see guest271314/ GoogleNetworkSpeechSynthesis . No need to sign up for a Google account to use this. I don't think Google's TTS is related to "AI".

This is how you can make the request yourself GoogleNetworkSpeechSynthesis.

If anybody want to build a TTS "module" or "component" that accepts and processes SSML input, and that the user can control - to an appreciable degree - on the front-end you can play around with this https://github.com/guest271314/GoogleNetworkSpeechSynthesis. (Makes an external request). Have fun!

It is possible to use Google Network Speech Synthesis service "free of charge", see GoogleNetworkSpeechSynthesis. On Chrome if you use Google voices with SpeechSynthesisUtterance() and window.speechSynthesis.speak() you are doing that anyway.

I implemented SSML parsing in JavaScript by hand for Web Speech API per SSML specification https://github.com/guest271314/SSMLParser, where the Web Speech API nor Firefox nor Chrome or Chromium browsers (Google does implement SSML parsing as a service https://github.com/guest271314/GoogleNetworkSpeechSynthesis) have implemented SSML parsing.

FYI when Google voices are used on Chrome or Chromium-based browsers the browser also makes a remote request, see https://github.com/guest271314/GoogleNetworkSpeechSynthesis.

How is processing SSML an attack vector? Google provides that capability as a service - with embedded limitations on character input that are not specified. This can and should be implemented in the browser - without making an external request; native-messaging-espeak-ng, GoogleNetworkSpeechSynthesis.

I just noticed that https://coqui.ai/ is "Shutting down".

I'm building a web app (React / Django) which takes a list of affirmations & goals (in Markdown files), puts them into a database (SQlite), and uses voice synthesis to create voice audio files of the phrases. These are combined with a relaxed backing track (ffmpeg), made into playlists of 10-20 phrases (randomly sampled, or according to a theme: "mind" "body" "soul") and then play automatically in the morning & evening (cron). This allows you to persistently hear & vocalize your own goals & good vibes over time.

I had been planning to use Coqui TTS as the local text-to-speech engine, but with this cancellation, I'd love to hear from the community what is a great open-source, local text-to-speech engine?

Generally, I learn both the highest quality commercially available technology (example: ElevenLabs), and also the best open-source equivalent. Would love to hear suggestions & perspectives on this. What voice synth tools are you investing your time into learning & building with?

lol this marketing technique is getting very old. https://github.com/coqui-ai/TTS is already amazing and open source.

Not sure how relevant this is but note that Coqui TTS (the realistic TTS) has already shut down

https://coqui.ai

I've used coqui.ai's TTS models[0] and library[1] to great success. I was able to get cloned voice to be rendered in about 80% of the audio clip length, and I believe you can also stream the response. Do note the model license for XTTS, it is one they wrote themselves that has some restrictions.

My only exposure to Coqui was their text to speech software. If I remember correctly the website was a commercialized service with TTS and probably some other related things. I hope the software work continues in the open.

Coqui.ai TTS (https://github.com/coqui-ai/TTS)

"tts_models/multilingual/multi-dataset/xtts_v2" model from https://github.com/coqui-ai/TTS. It gives pretty good results and works with references, so it's pretty easy to change the voice. By the way the source code of the project is open: https://github.com/volotat/Anagnorisis but be ready, the code is pretty raw for now.

A recent update to their GitHub also has a no-code gradio ui to facilitate fine-tuning and inferencing locally. https://github.com/coqui-ai/TTS/releases/tag/v0.21.3
