What is Free Audio Transcription Online?

Audio Transcription (or Audio Captioning) is a tool that converts spoken language from audio files into written text using the Whisper AI model. This tool leverages the 'tiny' version of the Whisper model, which runs directly within your browser, ensuring that your audio data remains private and is never uploaded to a server. It supports various common audio formats like MP3, WAV, M4A, OGG, and WEBM.

How it works

The tool utilizes a WebAssembly (WASM) implementation of the Whisper 'tiny' AI model, allowing it to perform speech-to-text transcription entirely client-side within your web browser. Upon uploading an audio file, the WASM model processes the audio locally, converting the spoken words into text. This local processing ensures fast transcription without any network latency and guarantees the privacy of your audio data.

Features & Benefits

  • Transcription happens entirely in your browser - your audio never leaves your device
  • Uses Whisper tiny model for fast, accurate transcription
  • Supports multiple audio formats including MP3, WAV, M4A, OGG, and WEBM

Frequently Asked Questions

How accurate is it?

Whisper-tiny is fast and works well for clear, clean English audio. For noisy recordings or heavy accents, accuracy drops - use a larger model for production transcription needs.
