Select your priorities & get a tailored recommendation
Accuracy & clarity
If your audio has accents, background noise, or technical terms:
- Whisper → excellent for challenging audio, many languages.
- Rev AI + human → highest accuracy, but more expensive.
- Sonix → strong accuracy with AI + editor.
Budget & volume
Large number of interviews or limited funding:
- Whisper (open-source) → free if you run locally (requires some setup).
- Otter.ai free → 300 minutes/month, good for small projects.
- Sonix pay-as-you-go → no subscription commitment.
Data privacy & compliance
If you work with vulnerable populations or strict IRB requirements:
- Whisper (local installation) → data never leaves your computer.
- Rev enterprise → signed confidentiality agreements.
- Sonix enterprise → GDPR & SOC2 compliant.

Hands-on challenge: Try a real transcription
Option 1 (quick test): Use an online free trial. Below are direct links to try each tool with a short audio sample (use your own 1-2 min test recording or their demo).
Challenge task:
- Record a 1-minute mock interview (or use a short evaluation-focused audio).
- Upload to two different tools from the table (e.g., Otter.ai free and Whisper via a free Colab notebook).
- Compare: accuracy, speaker identification, time taken, and ease of editing.
- Note which tool better preserves contextual M&E terms (e.g., "logic model", "outcome indicator").

Best practices for AI transcription in M&E
- Always review AI-generated transcripts for context-specific terms (M&E jargon, local names).
- For sensitive evaluations, mention AI transcription in your informed consent form and offer opt-out.
- Combine speaker labels with a quick human check — AI may confuse similar voices.
- Use timestamps for easy reference during qualitative analysis (NVivo / ATLAS.ti).
- Test with a 5-minute sample before committing to a tool for a large project.
