Whether it's journalism, user research or academic fieldwork, the analysis can't start until the interview is text. Trustample turns an hour-long recording into a time-coded transcript in minutes, with every word clickable for quick correction.
Privacy is built in, not bolted on: audio and video auto-delete after 30 days (transcripts are kept), any file can be deleted instantly, and paranoid mode destroys the recording the moment transcription finishes, which is useful when recordings are sensitive.
The craft difference between transcribing an interview and transcribing anything else is verification. A quote that goes into print or a findings report has to survive scrutiny, so the editor keeps every sentence tied to its audio: click the line, hear the moment, confirm the words. Names and technical terms, the things engines mishear most, go into the custom vocabulary box before upload, which measurably improves their recognition; whatever still slips through is a one-click fix that propagates to every export.

Frequently Asked Questions (FAQs)
Can it tell the interviewer and interviewee apart?
Yes, automatic speaker labels come on every paid plan. Two-person interviews label very reliably: segments arrive as Speaker 1 and Speaker 2, and renaming them to "Interviewer" and "Participant" updates the whole transcript.
How do I verify a quote is accurate?
Click the sentence in the transcript and the built-in player jumps to that exact moment so you can hear it. That's the fastest quote-checking workflow there is.
Is it safe for confidential interviews?
Files are stored encrypted and never used to train AI models. Audio and video auto-delete after 30 days; paranoid mode deletes the file immediately after transcription; and you can hard-delete everything, including your account, at any time.
What about interviews in Spanish or mixed languages?
Pick the spoken language before uploading for best accuracy; Spanish, English and 14 more are supported. Auto-detect works too, but explicit selection is more reliable for casual conversational audio.
How long does an hour-long interview take to transcribe?
Typically 2–5 minutes, running in the background, so upload a day's fieldwork and let the dashboard collect the results. Compare that with the 4–6 hours per interview hour that typing it yourself takes.
Can I transcribe a phone or in-person interview recorded on my phone?
Yes, voice-memo files (M4A on iPhone, various on Android) upload as-is. For in-person interviews, a phone on the table between you records well; for phone calls, check your local consent rules before recording.
An honest note: Interviews recorded in cafés or over bad phone lines are the classic hard case: background chatter competes with the voices, and accuracy drops. When the setting is noisy, placing the phone closer to the quieter speaker makes more difference than anything a transcription engine can do afterwards.
