Prepare the source

Follow your approved research protocol for consent, storage and access. Local processing does not replace those requirements.

Decide whether fillers, pauses and interruptions matter to the analysis before cleaning the text. Before processing a full recording, test a passage that includes the difficult conditions you expect in the rest of the material. A clean introduction may not reveal problems with quieter answers, room noise or changes of language later in the file.

Settings for this workflow

Set the audio language when you know it, and begin with Tiny to confirm the device can run the model. Compare another available model on the same passage if the first draft needs too much correction. Keep the task on original-language transcription unless an English translation is specifically the goal.

Review against the recording

Preserve a source transcript, then make a clearly labeled de-identified working copy. Keep the identity key under your own access controls.

Use the timestamp beside a segment to return to its audio. Correct the draft before copying a passage into another document. If a phrase remains unclear, leave an explicit marker in your working copy so the uncertainty survives later editing and sharing.

Illustrative handoff

Imagine a reviewer receiving the draft without having attended the session. They need the source recording identifier, the chosen transcription convention, a clear distinction between spoken words and notes, and a way to find unresolved passages. Make those choices visible in the exported document instead of assuming the next person will infer them.

TXT or DOCX for your coding workflow; JSON when segment times need to travel with the text. Keep the source audio under the access rules for this project. The app stores a local copy when browser storage permits; that convenience is not a substitute for an approved archive or backup.

Know the limit

Removing a hesitation can change the interpretation of an answer. Apply the transcription convention consistently across participants. If the work requires a managed transcription service, independent checking or a specialized record format, use a workflow that provides it. The useful result here is a transparent, reviewable draft.
