Transcription & speech recognition
Batch transcription
Batch transcription processes complete, already-recorded audio files, letting the system use full context in both directions for the best possible accuracy.
Because batch jobs are not latency-bound, they can run larger models, beam search and alignment passes. Everything from podcast archives to court recordings is batch work — the only question is turnaround time, measured by real-time factor and queue depth.
