What Makes This Feature Special

Discover the powerful capabilities that drive real business results

30+ Languages, One Platform

Reach customers in English, Spanish, French, German, Hindi, Arabic, and 25+ more. Your AI agents detect the language automatically and switch seamlessly without human intervention.

Top Transcription Providers

Connect Deepgram, OpenAI, Cartesia, ElevenLabs, Groq, Speechmatics, and Hamsa. Pick the provider that offers the best accuracy for your specific region or industry jargon.

Real-Time Accent Recognition

Struggle with thick accents or regional dialects? Our transcription models are trained to understand diverse speech patterns, ensuring your agent never misses a beat.

Zero Language Barriers

Expand your business globally without hiring multilingual staff. One AI agent handles calls from New York, London, Mumbai, and Dubai with equal proficiency.

Switch Language Mid-Sentence

Auto Language Switching is a system tool you switch on per agent. The agent opens in its transcription language and switches the moment the caller speaks another language or asks to switch, mid-conversation, without dropping the thread or restarting the call, and without a menu.

A Voice Chosen Per Language

Decide which languages the agent is allowed to switch into. The list comes from your transcription provider's supported set, and each language gets its own voice picked from your text-to-speech provider, or you can leave a language on the agent's default voice.

Frequently Asked Questions

Find answers to common questions about this feature

We support over 30 languages including English, Spanish, French, German, Italian, Portuguese, Hindi, Arabic, Mandarin, Japanese, Korean, and many more. The list is constantly expanding as providers add new language models.

You can connect OpenAI, Deepgram, Cartesia, ElevenLabs, Groq, Speechmatics, and Hamsa. Each provider has strengths in different languages and accents, so you can choose the one that works best for your specific needs.

Yes. Auto Language Switching is a system tool you enable per agent. The agent begins in its configured transcription language and switches as soon as the caller speaks a different language or asks to switch, with no keypress, no menu, and no need to restart the call. The conversation keeps its thread and any variables already captured.

Yes. Rather than switching into anything, the agent switches only into the languages you enable. The available list is drawn from your transcription provider's supported languages, so you are choosing from what your provider can actually transcribe.

Yes. Each enabled language can be assigned its own voice from your text-to-speech provider, which is useful when a language needs a different accent or a more natural-sounding speaker. Any language you leave unset falls back to the agent's default voice.

Yes. A realtime agent keeps its configured voice rather than switching voice per language, but language switching itself still works, and the agent will understand and respond in the new language. Per-language voices apply to agents using separate speech-to-text and text-to-speech providers.

Accuracy depends on the provider and the language. Providers like Deepgram and Speechmatics are excellent for regional accents and industry jargon. We recommend testing different providers to find the best match for your audience.

Absolutely. You can assign Deepgram to your sales team for speed, and Speechmatics to your support team for accuracy. Each agent can have its own transcription configuration.

Yes. You'll need to generate API keys from each provider's dashboard (e.g., Deepgram, OpenAI) and add them to VoiceInfra. This gives you full control over your usage and billing.

Yes. If a caller starts in English and switches to Spanish, the AI detects the change and adapts its responses immediately. This ensures a smooth experience for bilingual callers.

Multilingual support is included in your VoiceInfra plan. However, transcription costs are billed by the provider (e.g., Deepgram, OpenAI) based on usage. You only pay for what you use.

MCP Server for Claude & ChatGPT

VoiceInfra exposes your workspace as a Model Context Protocol server, so assistants like Claude and ChatGPT can read and manage it directly. Paste one region-pinned address, approve what the assistant may do, and it can list your agents, provision numbers, inspect call logs and build workflows without you switching windows. Permissions are grouped into areas a person actually recognises rather than raw scope strings, anything that spends your credit is surfaced on its own, and every connected app can be disconnected at any time. What a connected assistant can actually change is still bounded by your role in the workspace.
