Frequently Asked Questions
AssemblyAI performs speaker diarization when speaker_labels=true. It segments audio using word timings, computes speaker embeddings for segments, and clusters similar embeddings to assign labels (e.g., “Speaker A,” “Speaker B”). Accurate separation needs sufficient speech per voice—typically ~30 seconds—otherwise short interjections may be merged with the most similar speaker.
