Deepgram
Unified voice AI API for speech-to-text, text-to-speech, and voice agents
About Deepgram
Deepgram is a voice AI platform that combines speech-to-text, text-to-speech, and LLM orchestration into a single unified API for building real-time voice agents. It supports both real-time and batch processing and can be deployed in the cloud or self-hosted, and developers can create custom-trained speech models for enterprise accuracy needs. Its Flux models are conversation-aware, natively handling turn-taking, interruptions, and conversational context.
