User Voice Output EL TTS Alternative

[Goldstein777]

Is your feature request related to a problem? Please describe.
Not a problem but a cost efficient alternative for user voice output would be good for userbase scalability.

Describe the solution you'd like
Alternative TTS for user output that sounds natural enough.

Describe alternatives you've considered
Considered Microsoft TTS but not satisfying. Need more research.

Additional context
Maybe even alternative TTS for both user and gpt output, for users who don't want to spend for ElevenLabs at all. Like a cheap voice AI companion.
