Why teams choose Soniox over ElevenLabs
Engineered for real-world accuracy.
Soniox delivers production-grade accuracy in every language, not just clean studio audio. It understands fast, informal, accented speech, and handles mixed-language phrases, spoken codes, and alphanumerics with precision.
“It just gets the words right, any language, any accent, any context. That’s what accuracy is supposed to look like.”
ElevenLabs Scribe v2 Realtime is fast, but its real-world error rate is higher — it trails Soniox on accented, noisy, and conversational audio.
Real-time translation built in.
Soniox returns transcription and any-to-any translation from a single stream, in 60+ target languages, so your app works for 8 billion people without bolting on extra services.
“It’s so fast, captions appear before people even finish talking. Zero lag. No buffering. Nothing.”
ElevenLabs Scribe provides transcription only, with no translation in or out of the stream.
Know who’s speaking, live.
Soniox knows when someone’s speaking, when they’ve stopped, and who’s talking, with built-in real-time speaker separation, sentence boundary detection, and turn-taking awareness.
“Soniox knows who’s speaking and when each thought ends. The real-time transcripts read like true dialogue, not data dumps.”
ElevenLabs offers diarization only in batch Scribe v2 — not in the real-time streaming model.
One API. Everything built in.
Transcription, any-to-any translation, speaker separation, mixed-language support — all from a single model, endpoint, and call. Production-ready from day one.
ElevenLabs Scribe v2 Realtime covers transcription and language detection, but translation and real-time diarization aren’t part of the stream.
