Key takeaways
- 01Transcription runs locally with on-device speech recognition, so recordings stay on your device.
- 02Common formats — MP3, WAV, M4A, OGG, FLAC — are supported out of the box.
- 03Output is editable text you can copy, download as TXT, or paste into your notes.
Why transcribe locally?
Voice memos and interview recordings are usually private. Sending an audio file to a transcription service means handing over a clear, named voice — which is sensitive both ethically and under privacy law in many places.
On-device transcription avoids that trade-off: the audio never leaves the browser, but you still get the searchable, copy-able text you came for.
How to transcribe audio
Drop the recording, run the model locally, and copy or download the text.
- 01
Open the audio transcriber
Go to Handytool's Transcribe Audio tool and drop your recording onto the page.
- 02
Pick a language
Choose the language spoken in the audio. Auto-detect handles most cases when you are not sure.
- 03
Run the transcription
The browser loads the speech-recognition model the first time and runs it locally on the audio.
- 04
Copy or download
Edit the text inline if needed, then copy it or download it as a TXT file.
Before you transcribe
A few minutes of prep usually doubles transcription accuracy.
- 01Pick the cleanest copy of the recording — less background noise, less echo.
- 02Confirm the spoken language matches the language setting.
- 03For long recordings, split into chunks if your device runs out of memory.
- 04Trim leading silence so the model starts with real speech.
- 05Plan to skim the result for proper nouns — those tend to need manual fixes.
Audio transcription FAQ
Are recordings uploaded to a server?
No. The speech model runs in your browser, so the audio stays on your device.
Which languages are supported?
Major world languages are supported by the on-device model. Accuracy is highest for clear speech in well-resourced languages.
How accurate is the transcription?
Clean speech in a quiet room can hit 90%+ word accuracy. Background noise, overlap, or strong accents lower accuracy and need manual fixes.
Can I transcribe long recordings?
Yes, though long recordings use more memory. If your browser slows down, split the file into 10–15 minute chunks first.
