Voices that sound human, everywhere you need them.
Browse, preview, and tune production TTS voices — then use them in chat, assistants, transcripts, and podcasts. One voice catalog, consistent controls, streaming playback built for real workflows.
More than a speaker button
Five capabilities turn text-to-speech from a utility into a voice layer your whole platform shares.
Production-grade text-to-speech
Stream natural speech with realtime Cartesia and catalog-routed providers — tuned for chat read-aloud, long documents, and agent responses.
Fine-grained voice controls
Speed, emotion, language, and model selection per voice. Preview changes instantly before you commit them org-wide.
Speech in, speech out
Pair TTS with transcription and realtime voice chat. The same voice catalog powers read-aloud, assistants, and podcasts.
Multilingual by default
Browse voices across English, Spanish, French, German, Japanese, and more — one catalog, consistent controls everywhere.
Low-latency streaming
WebSocket streaming for interactive playback. Hear the first syllable fast, pause mid-sentence, resume without restarting.

From browsing voices to hearing them in production in three steps.
Browse the voice catalog
Open the playground, filter by language and provider, and audition voices with your own sample text.

Use it everywhere
Your picks follow you into chat read-aloud, voice assistants, transcript playback, and podcast generation.
