Description

I love this library. I think it would be great if it could pick up somewhat redundant packages like pyttsx3.. To do this though it would be useful to have more offline systems and smaller TTS systems.. e.g.

• speak-ng https://github.com/espeak-ng/espeak-ng
• Coqui https://github.com/coqui-ai/TTS (see https://github.com/Jiangshan00001/pyttsx4 which has supposedly done this)
• NSS Add support for NSS (Mac OS built-in TTS) #10
• Mimic3 (I have a feeling this will only work right now for linux so maybe not that useful.. ) https://mycroft-ai.gitbook.io/docs/mycroft-technologies/mimic-tts/mimic-3
• RHVoice (https://github.com/RHVoice/RHVoice)
• ekho (http://www.eguidedog.net/ekho.php)

For us personally - we'd love rhvoice and ekho (supporting hard to reach languages is really key).

Deeplearning tts and elevenlabs

Done as much as I think wise in #25 - a lot of these engines would be supported by pyttsx on windows if you use SAPI (RHVoice, Speak-NG), NSS is already supported by pyttsx3 (although broken iMHO. Forks of it have fixed them). Mimic3 and Coqui - sure. But they are right beasts to configure. Maybe later..
