What does Deepgram do?
Deepgram provides enterprise-grade voice AI APIs that enable developers to build applications with speech recognition, text-to-speech conversion, and voice agent capabilities. The platform offers both real-time processing for live audio streams and batch processing for pre-recorded content, making it suitable for various voice AI applications. What sets Deepgram apart is its unified Voice Agent API that combines speech-to-text, text-to-speech, and LLM orchestration into a single interface, reducing complexity and latency compared to stitching together separate components. The service emphasizes accuracy, cost-effectiveness, and realistic voice output, with options for both cloud-based and self-hosted deployments to meet different security and compliance requirements. Developers and enterprise teams building voice-enabled applications benefit most from Deepgram, particularly those creating customer service bots, transcription services, voice assistants, or any application requiring reliable speech processing. The platform is trusted by companies like Twilio, Cloudflare, and Sierra for powering their voice AI capabilities.
