Takes up to 20 transcript parts, each a list of segments with start, end and tex
Takes up to 20 transcript parts, each a list of segments with start, end and text, plus an optional speaker label and a time offset in seconds (where the part starts in the full recording). Offsets are applied, all segments are sorted by time, and the merged transcript is returned as a segment list, plain text with speaker labels, SRT and WebVTT. Overlapping segments from different speakers are kept and counted, which is normal for per-speaker tracks. Pure data processing; nothing is stored.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
