Its models are designed for conversational audio, including accents, multiple speakers, multilingual speech, and language switching within a sentence. The platform offers general-purpose, enhanced, medical, and voice-agent-oriented models for different transcription requirements.
Core capabilities include batch transcription from audio or video files and real-time transcription from live audio or video.
