About This Tool

The tool accepts an audio file and returns a text transcript. It supports optional features such as timestamps and subtitle exports (SRT/VTT) to fit publishing pipelines. Conceptually, it relies on automatic speech recognition (ASR) using acoustic and language models, followed by optional punctuation restoration and speaker labeling. Users provide an audio file, select language or enable auto-detect, and choose the desired output format. The core value is turning oral content into reusable, searchable text with consistent formatting for downstream editing, indexing, and accessibility. Beneficiaries include journalists documenting interviews, researchers analyzing lectures, podcasters creating show notes, and teams needing meeting records for compliance. Unique value lies in the combination of file-based input, flexible output formats, and optional features like timestamps and diarization, which streamline captioning and time-aligned transcripts. Core features include input validation, auto-language detection, punctuation restoration, and export in TXT, SRT, or VTT. Use cases span interview transcription, lecture capture, webinar archiving, and meeting minutes generation. The tool emphasizes accuracy, with clear caveats about ambient noise, speaker variety, and language coverage, guiding users to provide clean recordings for best results.

How to Use

  1. Provide inputs by uploading an audio file and selecting optional settings such as language and timestamps.
  2. Choose output format (TXT, SRT, or VTT) and transcription style (verbatim or cleaned).
  3. Run transcription to generate the transcript and, if requested, subtitle files.
  4. Review and edit the transcript if needed, then export or download the outputs.
  5. Save the transcript to your repository or attach to your media project.

Yes. Timestamps can be included in the transcript, and you can export SRT or VTT subtitle files for video captions or accessibility needs.
What impacts transcription accuracy?
