In short: For interview transcription on Speechma Pro, upload the recording (MP3, WAV, M4A, OGG or FLAC, up to about an hour), choose the spoken language and timestamps per sentence, then download the text. Sentence timestamps make it easy to find and verify quotes. It is included in Speechma Pro.

What is the easiest way to transcribe an interview?

Record the interview on your phone or computer, upload the file to Speechma Pro’s Speech to Text tool, choose the language and “timestamps per sentence”, and download the transcript. You get every answer in writing with a time marker, so checking a quote means jumping to 23:14 instead of scrubbing through the whole recording.

This works for many kinds of interviews: a local reporter talking to a city council member, an UX researcher running customer calls, a grad student collecting oral histories, or a hiring manager reviewing a recorded screening call.

How do I record and transcribe an interview?

  1. Get consent on tapeStart by saying, “I’m recording this so I can transcribe it accurately. Is that OK?” and let them answer on the recording.
  2. Record clean audioPut the phone between you, close to the person who will talk most. For calls, record each side if your app allows it.
  3. Save the fileiPhone Voice Memos saves M4A; most Android recorders save M4A or MP3. Zoom gives you an M4A audio file too.
  4. Upload and choose optionsOpen the Speech to Text panel above, upload the file, pick the language and timestamps per sentence.
  5. Generate and downloadStart. Download the text when it is ready.
  6. Label and verifyAdd “Q:” and “A:” or speaker names, then check every quote you plan to use against the audio.

How do I check quotes in an AI transcript?

Treat an AI transcript as a fast first draft, not a final record. Before a quote goes into an article, report or hiring decision, play the audio at that timestamp and confirm three things: the exact words, who said them, and the context around them.

Pay special attention to numbers (“fifteen” and “fifty” sound alike), negatives (“can” versus “can’t”), and names. A good habit used by many US newsrooms is to highlight every direct quote in the transcript and tick it off only after listening. For research, note the timestamp next to each coded excerpt so a colleague can audit your work later.

Do I need permission to record an interview?

Often, yes. Some US states, including California, Florida and Pennsylvania, require everyone on a call to agree before it is recorded. Universities usually require consent forms for research interviews, and employers may have their own policies. Ask first and keep the consent on tape. Speechma Pro processes your upload without storing it on its servers, and the transcript stays in your browser, even after a refresh, until you delete it.

What else helps with interview transcripts?

  • Keep a name sheet. Ask interviewees to spell their name and title at the start. It saves time when proofreading.
  • Avoid noisy cafes. Espresso machines and background chatter hurt accuracy more than a slightly quiet voice.
  • Split marathon sessions. A two-hour focus group should be cut into parts under an hour.
  • Turn findings into audio. Need to share a research summary with busy stakeholders? Paste it into text to speech and send a short MP3.

Frequently asked questions

Is interview transcription included in Speechma Pro?

Yes. Speechma Pro’s Speech to Text tool is included in your plan.

Can it tell the interviewer and interviewee apart?

The transcript gives you words and timestamps, not speaker labels. Sentence timestamps make it easy to see where each answer starts so you can add names.

How long can my interview be?

Up to 5 minutes per upload. Split longer interviews into 5-minute parts.

Is my interview recording kept private?

Uploads are processed and not stored on Speechma Pro servers. Your transcript stays in your browser, even after a refresh, until you delete it.

Can I transcribe a phone interview?

Yes, if you have a recording file. Many call-recording apps export M4A or MP3, which you can upload directly.

Can I transcribe interviews in Spanish?

Yes. Many languages are supported, including Spanish, French, German, Portuguese, Hindi, Chinese and Japanese. Choose the spoken language before you start.
