Open-source TTS/ASR models need faster, cheaper, more reliable inference
Problem
Users face high latency, high cost, and inconsistent quality when using open-source speech models, and there is a lack of affordable, high‑performance alternatives to closed‑source services like ElevenLabs.
Pain points
- High latency and cost when running open-source TTS/ASR models
- Inconsistent voice quality and occasional voice switching in generated audio
- Scarcity of cheap, high‑accuracy open-source alternatives to premium closed‑source services
Questions to verify
- Do users experience noticeable latency or cost barriers when integrating open‑source TTS/ASR into their products?
- Are there recurring complaints about voice quality inconsistency or unexpected voice changes in generated audio?
- Would a cheaper, high‑accuracy open‑source alternative to premium services like ElevenLabs be adopted by developers?
Evidence

Running at sub-50 ms latency at 10 RPS, this showed open models can be run much faster and cheaper.

This is awesome. Thanks for pushing the audio pareto frontier forward.Probably far fetched for now, but I think the next big evolution is building the pareto/much cheaper alternative to GPT-Live-1.

All TTS generations are too fast. It's almost I'm listening to a podcast on 1.25-1.5x speed.

For some reason it switched voices half way through a 33 second clip.For OP the clip name is nari-nina-01a0a12f-980a-765e-8029-fa56bd23210d.wav
