MAI-Transcribe-2-Streaming is a low-latency speech-to-text model for real-time transcription. Send audio as a continuous stream and receive incremental transcripts while the speaker talks. Intermediate results update the current transcription, and final results confirm each segment.

The model supports live audio workloads such as call centers, voice assistants, meeting and lecture captioning, voice-driven interfaces, and real-time note taking.
