What Is an Audio to Text Converter?
An audio to text converter recognizes spoken words in a recording and turns them into editable text. Use it for interviews, podcasts, meetings, lectures, voice memos, and other permitted recordings.
Upload an audio file or record from your microphone, choose the spoken language or use automatic detection, and export a transcript with timestamps. The multilingual Whisper Tiny model runs directly in your browser.
Multilingual speech recognition
Use automatic language detection or select English, Chinese, Spanish, French, German, Japanese, Korean, Portuguese, or Italian.
Timestamped transcript
Review speech in timed sections and download SRT subtitles as well as a plain TXT transcript.
Upload or record
Transcribe an existing audio file or create a new microphone recording without installing desktop software.
How to Convert Audio to Text Online
The first transcription downloads Whisper Tiny and caches it in the browser. Later sessions can reuse that model cache.

How to Improve Whisper Transcription Accuracy
Whisper Tiny favors speed and a smaller download. Recording quality still has a major effect on the transcript.
Use clear close-mic speech
Reduce background music, echo, overlapping speakers, and distant microphone sound whenever possible.
Select the correct language
Choose a specific language when automatic detection is uncertain or the recording is short.
Review names and technical terms
Small speech recognition models can miss uncommon names, brands, abbreviations, and specialist vocabulary.
Keep the tab open
Long audio is processed in 30-second sections. Avoid closing the page until the final transcript appears.
