AI audio platform for speech, agents, music and dubbing
Generate expressive speech across 90+ languages with multiple model options tuned for latency, consistency or emotional range.
Create instant voice clones on starter plans and professional clones on higher tiers, or design voices from a text prompt.
Configure, test and monitor agents that handle voice and chat conversations across phone, messaging and support channels.
Translate and dub video and audio into other languages, with automatic and studio workflows plus watermark options.

Snapshot testing for AI behavior — catch regressions offline in CI
A live run captures every model request and response into a local SQLite cassette that CI can replay offline and deterministically at zero cost.
Point EvalCore at OpenAI-compatible endpoints, vLLM, Ollama, your own REST APIs, shell commands, or OTel/OpenInference traces — no SDK required.
Stack contains, judge-rubric and other scorers in YAML to express exactly what a correct answer looks like for each case.
Compare against a baseline branch so only real regressions fail, and let the process exit code gate your pull requests.
