Audio to text from any recording
Audio reaches you from many devices and apps, and each saves it differently. iPhone Voice Memos and many Android recorders save M4A. Dictaphones and older recorders often use MP3 or WAV. Podcasts are usually MP3. WhatsApp and Telegram voice messages are Opus files. Some call recorders save AMR, and music and archive work tends to use FLAC or AIFF.
RocketScribe accepts all of these. You upload the file as it is, and you do not need to convert it to MP3 first. The full list of supported audio formats is below.
- MP3, M4A, AAC and WAV
- OGG and OPUS
- FLAC, AIFF and WMA
- AMR from phone call and voice recorders
Three ways to bring audio in
Upload a file from your computer or phone. Uploads are sent in parts, so a long recording on a weak connection can resume with Retry instead of starting again.
Record from your microphone in the browser. This suits a quick dictation or notes you want written down straight away. The recording goes into the same transcript editor as an upload.
Import from a link. Direct file links, Dropbox, Google Drive and SoundCloud work. This saves downloading a large file to your device only to upload it again.
What you get after the audio is converted
The transcript arrives with timestamps and is split into paragraphs. A synced player highlights the line being spoken, and clicking any line jumps the audio there. That makes checking easy: listen, spot a wrong word, click and type the fix.
You can rename speakers in the editor. Automatic speaker identification, which labels who said what, is available on paid plans or with a Minute Pack. It is not part of the free plan or the no-sign-up trial.
Choose the export that fits the job
The same transcript can leave RocketScribe in several forms, and you can turn timestamps and speaker names on or off for each export.
- TXT for plain notes or pasting into another tool.
- DOCX for a Word document you will edit, comment on or send.
- PDF for a fixed copy to file or share.
- SRT or VTT if the audio goes with a video and needs subtitles.
- CSV for a spreadsheet with a start time, end time and text on each row.
- AI prompt to copy the transcript with a ready prompt into ChatGPT or Claude for a summary or action points.
- Share link for a read-only page others can open in a browser.
What affects audio transcription accuracy
RocketScribe uses modern Whisper-class speech recognition. Clear speech close to the microphone transcribes very well in most languages. Accuracy drops with background noise, people talking at the same time, music under the voice, a microphone far from the speaker and heavy accents. Recording format matters much less than recording conditions. A clean MP3 will beat a noisy WAV.
Language detection is automatic, or you can choose the language per file, which helps with short clips. Recordings that switch between Chinese and English are handled in one transcript. Your files are never used to train AI models, and you can delete them whenever you like.
Recording tips for better text
If you are about to record something you plan to transcribe, a few habits make a clear difference to the result.
- Put the phone or microphone close to the person speaking, not in the middle of a large table.
- Turn off music, fans and TVs in the room if you can.
- Ask people to take turns. Overlapping speech is the hardest part for any speech recognition.
- Upload the original file rather than a copy that has been compressed again by a messaging app.
