How It Works
Share a voice memo to Files, upload the M4A here, and receive a text transcript in minutes. AAC compression is efficient for speech — you do not need to convert to WAV first unless troubleshooting quality issues.
Use Cases
Students transcribe professor voice memos, real-estate agents log property walkthrough notes, and therapists draft session summaries from dictated M4A files (ensure you comply with local privacy laws).
Limitations
Very long files may take several minutes. Accuracy depends on audio quality, background noise, and speaker clarity. For best results, use clear recordings.

Frequently Asked Questions

Rename the file to end in .m4a and ensure it is not DRM-protected. Memos synced through iCloud should download fully before upload.
