Transcription models for words and laughter annotations
Evaluate ElevenLabs Scribe v2 batch for a structured transcript containing speech and non-speech events, and MOSI Intelligence’s MOSS-Audio for a broader transcription-plus-audio-understanding workflow. Verify the output contract: a description mentioning laughter is not automatically a time-aligned transcript event.
Compare the actual result contract
| Candidate | Verified basis | Integration consequence |
|---|---|---|
| Scribe v2 batch | Dynamic audio tagging and an audio_event category |
Most direct documented baseline for an event-bearing transcript |
| MOSS-Audio | Transcription plus acoustic-event understanding | Relevant open-model trial; validate the required schema and event boundaries |
The MOSS-Audio documentation also describes timestamped speech recognition. Speech-word timestamps do not by themselves establish accurate laughter boundaries. For an editing product, preserve separate checks for the spoken text, event label and temporal location. If a descriptive model needs a second alignment stage, include its errors and operating cost in the comparison rather than describing the pipeline as one native structured output.
Distinguish documented output from a candidate capability
ElevenLabs’ transcription documentation defines an audio_event output category for non-speech sounds such as laughter or applause. MOSS-Audio covers speech and environmental-sound understanding, and its inference instructions include transcription. That makes it relevant for a combined editorial trial; it does not establish an equivalent event schema or guaranteed alignment.
Define what an editor actually needs
An editing transcript should distinguish spoken words, audible events and interpretive notes. A laugh is an event; a claim that a person is mocking another person is an interpretation that may be unsupported.
| Output field | Proposed rule |
|---|---|
| Spoken text | Preserve speech without inserting invented words |
| Event label | Use a controlled vocabulary such as laughter or applause |
| Time span | Preserve uncertainty when boundaries are unclear |
| Speaker association | Leave unassigned when attribution is not supported |
| Editorial note | Keep interpretation separate from observed sound |
Test overlap and false positives
Include quiet laughter, laughter over speech, applause without speech, breaths, music and room noise. Have an editor annotate the clips before seeing model output. Track missed events and invented events separately from word errors. A system can transcribe correctly while omitting every laugh, or detect laughter while losing nearby words.
Run the result through the editing tool. Confirm that event labels survive export and that their timestamps point to the intended audio. For a composed pipeline, store provenance for both recognition and event generation so mismatches can be repaired.
Selection rule
Use Scribe v2 batch as the documented structured-event baseline. Prioritize MOSS-Audio when the team also needs descriptive sound review in the same open model workflow, provided a trial validates event detection and any required alignment. Do not sell a narrative caption as a drop-in replacement for an editor’s event transcript.
