Call duration versus usable speech: counting audio honestly
Clarify whether dataset volume means elapsed recordings, speech activity, or reviewed task-ready material.
← Call Datasets
Fiund / Quality & provenance
Keep the source, signal, and review connected.
A useful call datasets collection needs traceable context as well as usable files. Define what will be checked, how findings will be recorded, and which questions remain open.
Technical criteria
Category-specific acceptance starts here.
Source and scenario
Real or staged; inbound or outbound; industry, date range, and interaction types.
Audio channels
Mono mixture, stereo separation, or independent tracks; source encoding and sample rate.
Transcript scope
Verbatim or normalized text, timestamps, speaker labels, overlap, and non-speech conventions.
Permission and privacy
The specific proposed training uses, relevant source permissions, and de-identification requirements.
Review framework
Four separate questions for each collection.
| Review layer | What to establish | Evidence to request |
|---|---|---|
| Source lineage | Where this exact file or record came from and how it relates to other versions. | Stable identifiers, source references, and derivative relationships. |
| Technical fit | Whether the recorded fields and signal support the defined model task. | A representative inspection, file-level metadata, and issue records. |
| Annotation fit | Whether labels have the required meaning, timing, and consistency. | Written conventions, reviewed examples, and known limitations. |
| Permission scope | Whether the proposed use has been reviewed for the selected material. | Project-specific source documentation and agreed terms. |
Illustrative manifest
A manifest should describe the state of review.
