Frequently asked questions
Reson8 is built for European languages and gets the words right that matter most. Generic speech models mishear medication names, order numbers, addresses and case references. Reson8’s speech-to-text adapts to your domain-specific terminology in real time or from a single text upload, no fine-tuning or audio samples needed.
We have full support for 10 languages: English, German, Spanish, French, Dutch, Italian, Polish, Portuguese, Swedish, Frisian.
Reson8 routinely leads speech-to-text benchmarks from third-parties such as Hugging Face, Artificial Analysis, Coval, and Voice Arena.
Yes, a single stream can switch dynamically between languages mid-conversation. Language detection is automatic and out-of-the-box, no manual language flagging necessary. Find more information on language detection here.
Yes, diarization is supported across all endpoints, ensuring transcripts accurately distinguish between speakers no matter the complexity of the audio. Find more information on diarization here.
Each endpoint is applicable for a different use case:
- Prerecorded: for complete audio files, uploaded over REST. You get the full transcript back in a single response.
- Realtime: for live audio streamed over WebSocket, when you want to show live transcripts while speaking.
- Turns: also a WebSocket stream, but it detects when a speaker starts and stops talking, returning the transcript of each turn separately. Use this endpoint for cases like voice agents, when you need low latency end-of-turn detection and native barge-in.
