Deepgram Nova-2 delivers industry-leading 150ms speech-to-text latency. Words are recognized almost as they are spoken, enabling truly real-time voice interactions.
Real-time streaming support means the agent starts processing intent before the caller finishes speaking. Partial results flow continuously for minimal response delay.
Nova-2 achieves best-in-class word error rates across accents, dialects, and noisy environments. Custom vocabulary and domain-specific models further improve accuracy.
Broad language support including English, Hindi, Spanish, French, German, Portuguese, Japanese, Korean, and major Indian languages with accent-aware models.
Advanced noise suppression handles real-world environments -- traffic, office chatter, poor phone lines -- without degrading recognition accuracy.
Add industry-specific terms, product names, and jargon to ensure accurate recognition of your domain language. Boost accuracy for medical, legal, or technical terms.

Languages
Caller audio from your telephony provider is streamed in real-time to Deepgram's Nova-2 model via WebSocket for continuous speech recognition.
Deepgram transcribes speech in 150ms with streaming partial results, so the LLM can begin processing intent even before the caller finishes their sentence.
The transcribed text is passed to your chosen LLM (GPT-4o, Gemini, Claude) for intent understanding, context management, and response generation.
The LLM response is converted to natural speech via your chosen TTS provider (ElevenLabs, Azure, Sarvam) and streamed back to the caller.
"Deepgram's streaming STT is what makes our agent feel instant. The 150ms recognition means our agent starts thinking before the customer finishes talking. Total response time dropped by 40%."
