Who Uses Musely Voice Recording Transcription
Turn iPhone voice memos into actionable text
I dictate 5-6 voice memos a day between meetings and while commuting. Musely accepts my M4A files directly from iPhone Voice Memos and the Quick Clean preset strips the ums and uhs. I paste the text into Notion and my running to-do list stays current.
Convert client phone calls into CRM follow-ups
I record every discovery call on my phone and used to spend 20 minutes after each one writing CRM notes. The Meeting Notes preset extracts decisions and action items with ownership. Speaker Labels separate my voice from the client. I paste straight into Salesforce.
Transcribe phone interviews with accurate speaker attribution
I interview sources on WhatsApp voice messages in 4 different languages. Musely accepts the OGG/OPUS files without conversion and auto-detects the language. The Interview preset formats every quote with clear attribution, ready for fact-checking.
Dictate patient notes via voice memo
After each patient visit I record a 3-minute voice memo summary. Musely's Quick Clean preset produces polished clinical notes I paste into our EHR. Session-only processing is essential since recordings contain patient information. Saves me 30 minutes per day.
Convert lecture and study group recordings to notes
I record 60-minute lectures and study groups on my Android. The M4A and OGG formats upload directly. Timestamps let me jump back to specific topics when studying, and the Verbatim preset gives me exact quotes for term papers.
Produce verbatim transcripts from field interviews
My IRB requires verbatim transcripts with every filler word and non-verbal marker preserved. Verbatim preset keeps uh, um, [pause], and [inaudible] intact. I upload 2-hour M4A field recordings and Musely processes the full duration without splitting.

What Users Say
4.8/5 based on 2,780 reviews
“I record every sales call on my iPhone and upload the M4A straight to Musely. The Meeting Notes preset pulls out commitments and next steps automatically. Cut my post-call admin from 25 minutes to under 5. Easily saves me 3 hours a week.”
“WhatsApp OGG support changed my workflow. I interview sources across 3 continents and their voice messages used to need conversion before I could transcribe them. Musely handles the OGG files directly and auto-detects Spanish, Portuguese, and Arabic. Transformed my field journalism workflow.”
“I dictate post-visit patient notes as voice memos throughout the day. Quick Clean preset produces polished clinical text in seconds. Session-only processing gave me peace of mind about HIPAA. Saves roughly 45 minutes of documentation work per day.”
Frequently Asked Questions

Musely natively accepts iPhone M4A Voice Memos and WhatsApp OGG/OPUS files without conversion, while Otter.ai focuses on summaries and Notta requires an app. Musely also offers 4 distinct presets for different voice memo scenarios and supports recordings up to 120 minutes on free credits.
The Speaker Labels toggle in Musely activates automatic speaker diarization. Each speaker's turn appears on its own line with Speaker 1, Speaker 2 markers, or names if mentioned. Works for 2-party phone calls and multi-person conference calls. The Interview preset formats the entire transcript as Q&A.
Musely accepts M4A (iPhone Voice Memos), AAC (Android), OGG/OPUS (WhatsApp), MP3, WAV, WebM, MOV, and MP4 files up to 120 minutes each. No format conversion step is required — upload the file exactly as your phone saved it.
Seed-ASR 2.0 includes noise-robust speech recognition tuned for mobile environments. Musely handles typical street noise, office background, and cafe ambience without significant accuracy loss. For very noisy recordings, the Quick Clean preset smooths the resulting text for readability.
The Output Language setting translates the transcript into 48 target languages including English, Mandarin, Spanish, Japanese, Arabic, Hindi, French, and German. Musely transcribes the original audio, then translates the output so you receive both source and target text.
Musely processes voice recordings in an isolated session environment and removes them after the transcript is delivered. Audio is never used to train AI models, which matters for sales calls, clinical notes, and personal voice memos. No files are retained beyond your active session.
