Speech Service Providers¶
Speech service providers enable voice capabilities in Open Chat Studio, including text-to-speech (TTS) and speech-to-text (STT). Configuring a speech provider allows chatbots to synthesize spoken audio from text and transcribe audio input to text.
Supported providers¶
- ElevenLabs — TTS, STT, and voice management including custom voice cloning
ElevenLabs¶
ElevenLabs is an AI audio platform offering high-quality voice synthesis and transcription.
Capabilities¶
| Capability | Details |
|---|---|
| Text-to-Speech (TTS) | Converts text to MP3 audio using ElevenLabs voices |
| Speech-to-Text (STT) | Transcribes audio using ElevenLabs Scribe v2 |
| Voice sync | Syncs available voices from the ElevenLabs catalog to OCS |
Setup¶
- Obtain an API key from your ElevenLabs account.
- In Open Chat Studio, navigate to Team Settings → Speech Service Providers.
- Add a new provider, select ElevenLabs, and enter your API key.
- On creation, OCS will automatically sync available voices from your ElevenLabs catalog.
Voices¶
When you create or edit an ElevenLabs provider, OCS fetches and stores the voices available in your ElevenLabs account. You can trigger a manual re-sync from the provider's edit page to pick up newly added voices.
Custom voices: Custom voices must be created directly in ElevenLabs. OCS does not support creating custom voices. Once created in ElevenLabs, they will be synced to OCS the next time a sync runs (automatically on provider creation, or manually on request).
OCS does not support creating custom voices directly — manage your voice library in ElevenLabs and let OCS sync the results.
