Voice & turn-taking
Caller switches language.
Finn switches too.
Detect language at every turn. Switch synthesis + transcription mid-call. No re-routing, no second agent, no awkward 'hold while I transfer you.'
30-minute free trial. No card. No procurement.
How it works
Detect.
Switch. Continue.
Drag, wire, deploy. Each step is reversible — every save creates a versioned snapshot.
Per-turn language detection
Every caller turn classified for language. Sub-200ms classification overhead.

FAQ
Questions and answers.
Which languages are supported?+
46 languages including English (multiple accents), Spanish, Mandarin, Hindi, Tamil, Arabic, Portuguese, French, German, Japanese, Korean, and most major European + Asian languages.
How quickly does the switch happen?+
Mid-sentence — typically <300ms from detected language change to first response in the new language. Caller experiences it as natural.
Is the conversation context preserved?+
Yes — captured fields, intent, sentiment, workflow position all carry across the language switch. No restart, no 'let me get my colleague.'
Can I lock a Finn to one language?+
Yes. Per-finn configuration if your business operates in one language only. Default is auto-detect across all 46.
Does the voice change with the language?+
Cloned voices that support multiple languages (most of our library) keep the same persona across all of them. Stock voices may switch to a native speaker for that language.
