AUDIO / AI INDEX 11
A voice AI platform for text-to-speech, voice workflows, and audio production, with a free tier and developer API.
BASE ARCHITECTURE / Proprietary voice models S Instant Cloud Web Studio (0 GB VRAM • Free / $5 mo+)
If you need premium voices, this is the default. Kokoro-82M is 60% of the quality for free — the gap is voice cloning and language coverage.
ILLUSTRATIVE PROMPT
Narrate a short product introduction in a calm, clear voice.
