Frequently Asked Questions - AMR Voice Note Transcription

What formats are supported?

We support AMR (narrow-band) and AMR-WB (wideband, .awb extension) - both commonly produced by mobile phones, WhatsApp, and VoIP applications.

How accurate is AMR transcription?

AMR uses a narrow-band codec (typically 8 kHz) which limits audio quality compared to MP3 or WAV. Heavy background noise or very compressed files may reduce accuracy. Review the transcript against the recording before using it.

Can I transcribe WhatsApp voice notes in AMR format?

Yes. WhatsApp voice notes are typically saved as .opus (Android) or .m4a (iOS), but some older versions or exports produce .amr files. AMR files from WhatsApp exports can be uploaded directly.

Can you separate different speakers?

Yes. Speaker diarization labels each unique speaker in the transcript. Works well for two-party calls and smaller multi-person groups.

What output formats are available?

TXT (plain text), DOCX (editable Word document), SRT (subtitle file with timestamps), and VTT (WebVTT subtitle file).

Is my recording kept private?

Files are encrypted in transit and at rest. How long they are kept depends on your plan.
