Transcribe interviews and recorded conversations to text. Built for journalists, qualitative researchers, market researchers, and anyone with hours of interview tape. Speaker labels for interviewer and guest, word-level timestamps for precise quote extraction, SRT/VTT subtitles, 99+ languages.

How to transcribe an interview in 4 steps

1. Upload your interview recordings — drop .m4a, .mp3, .wav, .mp4, or any common format into the Upload Interview Recordings field. Bulk uploads supported.
2. Pick your options — auto-detect language or pick from 99+, toggle speaker diarization to separate the interviewer from each guest, optionally translate non-English interviews to English.
3. Run the actor — recordings process 10 at a time in parallel on the paid tier; an entire project's interviews can be transcribed in one run.
4. Download results — every recording lands in the dataset with the transcript, segment + word-level timestamps, speaker labels, and ready-to-use SRT/VTT subtitle strings.

Supported formats: M4A, MP3, WAV, FLAC, AAC, OPUS, OGG, MP4, MOV, WebM. Max 1 GB per file on the paid tier.

Built for journalists, qualitative researchers, market researchers

• 📰 Journalists — turn phone-recorded interviews into clean transcripts ready for quote pulling
• 🧪 Qualitative researchers — preserve participant voices with speaker separation for thematic analysis
• 📊 Market researchers — bulk-transcribe focus group and 1:1 interview tapes
• 📚 Oral historians — searchable, time-stamped archives of long-form interviews
• 🎙️ Podcasters publishing interview shows — transcripts for show notes, blog repurposing, and SEO

Speaker diarization (interviewer / guest separation)

Toggle the Speaker Diarization input and the actor automatically labels every segment and every word with the speaker it came from (SPEAKER_00 for the interviewer, SPEAKER_01 for the first guest, SPEAKER_02 for the second, etc.). This makes it trivial to extract clean quote attributions for journalism or coding qualitative data for research. Powered by pyannote-audio. Charged per audio second; only billed when enabled.

Translate foreign-language interviews to English

Toggle Translate to English and the actor returns the transcript translated into English while preserving timing — perfect for conducting interviews in your subject's native language and publishing in English. Combine with Speaker Diarization to get clean, attributed quotes in both directions. Charged separately when enabled.

SRT / VTT subtitle export

Every transcription returns ready-to-use srt and vtt subtitle strings. Save the field value as a .srt or .vtt file and:

• Publish a video version of the interview with subtitles for YouTube, Vimeo, or your CMS
• Add HTML5 <track> accessibility captions to embedded video
• Build a searchable interview archive with timestamps

Set Timestamp Granularities to word for cue precision down to individual words.

FAQ

How accurate is interview transcription? Powered by an industrial speech-to-text pipeline tuned for natural conversation. Accuracy is typically 95–99% on clean studio or quiet-room interviews, lower on phone-recorded or noisy field interviews. Word-level timestamps are returned even when accuracy is imperfect, so you can verify and correct quote attributions quickly.

What audio and video formats are supported? M4A, MP3, WAV, FLAC, AAC, OPUS, OGG, MP4, MOV, WebM. Max 50 MB per file on the free tier, 1 GB on the paid tier.

Can I transcribe foreign-language interviews? Yes — auto-detection across 99+ languages including Spanish, French, German, Mandarin, Japanese, Portuguese, Arabic, Hindi, Russian, and many more. Toggle Translate to English to receive an English transcript alongside the timestamped original.

Is speaker diarization included? Yes, opt-in via the Speaker Diarization toggle. Each segment and word gets labeled SPEAKER_00 (interviewer), SPEAKER_01 (first guest), etc. Powered by pyannote-audio. Billed at $0.0001 per audio second only when enabled.

How does pricing work? Pay-per-audio-second. The free tier covers small jobs and testing without a credit card. The paid tier is $0.0005 per second of audio. A 1-hour interview with diarization is approximately $2.16 — versus Rev.com at ~$90 for the same length.

Can I integrate this into my qualitative research workflow? Yes. The actor exposes a standard Apify run/dataset API. The dataset record includes transcript, segments[].words[], srt, and vtt ready to feed into NVivo, MAXQDA, Atlas.ti, Dovetail, or any qualitative analysis tool that accepts plain text or VTT.

What if my interview is multi-speaker (panel, focus group)? Speaker diarization handles up to ~6 distinct speakers reliably. Each speaker is labeled SPEAKER_00 through SPEAKER_N in temporal order of first speaking turn.

How long does a transcription take? A 60-minute interview takes 1–3 minutes on the paid tier. Bulk batches of 10 interviews complete in 5–10 minutes (parallelized).
