About audio transcription

Vidxt turns spoken audio into readable, searchable text directly in your browser. Upload an interview, lecture, podcast or voice memo, and you get a clean transcript you can copy, edit or export within minutes.

Speech recognition runs against your file through a high-accuracy engine that handles English, Chinese, Japanese, Korean and several other languages. Punctuation and casing are restored automatically, so the output reads close to natural writing instead of a flat string of words.

Who this is for

  • Journalists and researchers who need to quote interviews accurately and want a text version to search through instead of scrubbing audio for the right quote.
  • Students and academics turning recorded lectures or seminars into notes, study guides or citations without retyping everything by hand.
  • Podcasters and content creators producing show notes, blog posts or social clips from existing episodes to improve discoverability and reuse.
  • Teams reviewing customer calls, user interviews or internal meetings who want a written record they can share, comment on or feed into other tools.

How to transcribe an audio file

  1. 1Drop an MP3, WAV, M4A, AAC, FLAC or OGG file into the upload area, or click to pick one from your device. Files up to 2 GB on desktop and 500 MB on mobile are supported.
  2. 2Pick the spoken language so the engine can apply the right acoustic model. Auto-detect works for most clean recordings, but choosing the language helps with accents and short clips.
  3. 3Start the transcription and wait for the result. When it finishes, review the text inline, fix any names or terms, then copy it or export as plain text or SRT subtitles.

Supported audio formats

Vidxt accepts the common audio formats you actually have on disk: MP3, WAV, M4A, AAC, FLAC and OGG. If your file is a video instead, you can run it through the video transcription tool, which extracts the audio track automatically before recognising speech.

Your files stay on your device

Decoding and pre-processing happen locally through FFmpeg compiled to WebAssembly. The audio is sent to the speech engine only for the seconds it takes to generate text, and nothing is stored on our servers afterwards, so sensitive recordings do not sit in a cloud bucket.

Frequently asked questions

How accurate is the transcription?

On clear single-speaker audio you can expect well above 90% word accuracy. Background noise, heavy accents, overlapping speakers or low bitrate recordings will reduce that, so a quick proof-read is still worth doing.

Which languages are supported?

English, Simplified and Traditional Chinese, Japanese, Korean, Spanish, French, German, Portuguese and several more. Mixed-language recordings work but tend to be most reliable when one language clearly dominates.

Is there a length limit?

File size is capped at 2 GB on desktop and 500 MB on mobile, which covers multi-hour recordings at normal bitrates. Very long files take longer to process; splitting them into chapters often gives faster, more manageable output.

Can I use it for free?

Yes. Day-to-day transcription is free, with no signup required for short clips. Heavy users who run long files frequently can move to a paid plan for higher monthly limits and priority processing.
