Language Support

Omniflow’s language coverage depends on the channel and the underlying provider. This page is the canonical matrix.

Chat / text

Chat UI is fully localized for EN, DE, FR, ES. Other languages are supported for content but the surrounding UI uses the closest of those four.

Voice — Realtime

Realtime voice agents inherit language coverage from the underlying provider:

For high-fidelity multilingual voice, use Gemini Live as the primary and Cascaded as the fallback.

STT (cascaded)

Cascaded mode lets you bring your own STT and TTS, which expands language coverage. Supported STT providers:

TTS (cascaded)

DTMF (touch-tone keypad)

DTMF input is supported in voice-to-voice flows for IVR-style interactions:

Agent: "For account balance press 1, for transfers press 2."
       (DTMF tone detected)
Agent: "Looking up your balance..."

Configure DTMF prompts in the agent’s prompt; Omniflow detects the tones from the audio stream and surfaces them as dtmf:<digit> events in the trace.

Speech Analytics language coverage

The Speech Analytics scoring grader works on every language the underlying STT supports. Rubric criteria descriptions can be authored per-language so the grader scores in the local language’s idiom.

Mixed-language conversations

The agent auto-detects the customer’s language from the first turn and switches. For mixed-language emails (common in DACH and the Indian subcontinent), the Email Robot Assistant detects per-paragraph language and replies in the dominant one — or in a configured preferred language.

What “supported” means

If your language isn’t listed and you have a use case, contact your account team — most languages can be enabled within 2-4 weeks of customer-led tuning.
