SpeechCortex

Engineering Team

RT-Zeus delivers real-time conversational speech recognition that transcribes audio as it's spoken. The engine is specifically optimized for Voice AI agents and features integrated end-of-turn detection.

Purpose-built for real-time applications including voice assistants, live captioning, and interactive applications requiring fast, responsive feedback.


Transcription

RT-Zeus provides native WebSocket support for seamless streaming integration. Bidirectional communication enables real-time audio processing with efficient data transfer and minimal overhead.

Our streaming architecture processes audio in small chunks, delivering interim and final transcriptions as speech occurs. This approach minimizes perceived latency and enables immediate visual feedback for users.

The WebSocket implementation handles connection management, automatic reconnection, and graceful error recovery. This ensures reliable streaming even in challenging network conditions.
