emotion label plus a time series of consecutive fixed-length windows, each with its own label. It is a pure classification endpoint — no transcript, diarization, or enrichment data is produced.
Each
time_series entry covers one fixed-length window, delimited by its start_ms and duration_ms; a trailing remainder shorter than one full window is omitted. A file shorter than one window returns an empty time_series — the whole-file emotion label is always present.
If you need emotion labels alongside a transcript, use the
emotion_signal enrichment on Multilingual Transcription instead — see Transcription enrichment features.Authentication
