# Whisper Web transcription samples

These short recordings let you check the local workflow before selecting your own media. Listen to the audio, select the matching spoken language, transcribe it and compare the result with the dataset reference.

| Sample | Duration | Audio | Reference |
| --- | ---: | --- | --- |
| English | 10.56 seconds | [WAV](https://whisperwebfree.com/samples/en.wav) | [Reference text](https://whisperwebfree.com/samples/en-reference.txt) |
| Spanish | 12.84 seconds | [WAV](https://whisperwebfree.com/samples/es.wav) | [Reference text](https://whisperwebfree.com/samples/es-reference.txt) |

The reference files are dataset transcripts, not guaranteed Whisper output. The clips contain read speech; they do not represent noisy meetings, overlapping speakers or a one-hour recording. Review names, numbers and timestamps before using any transcript.

## Local workflow

- [Standard transcription](https://whisperwebfree.com/): up to 300 MB and 20 minutes.
- [Large-file transcription](https://whisperwebfree.com/large-file-transcription): local files up to 1 GB and 1 hour, processed in sections.
- [Transcribir audios largos](https://whisperwebfree.com/es/transcribir-audios-largos): the Spanish large-file tool.

The browser still downloads the application and model. Selected local media is processed on the current device. Keep the tab open during processing and export results you need to keep. Sample attempts are identified separately in optional usage measurements.

## Observed browser tests — 3 October 2026

Chromium 154 on macOS, Whisper Tiny (q8), WebAssembly. The English clip completed in the standard tool; the Spanish clip completed in the large-file tool. Both WAV inputs are 32-bit float, 16 kHz, mono. Both results were stored in local history, and the TXT/SRT/VTT export contents were inspected.

| Sample | Actual text | Actual subtitles |
| --- | --- | --- |
| English | [TXT](https://whisperwebfree.com/samples/en-output.txt) | [SRT](https://whisperwebfree.com/samples/en-output.srt) · [VTT](https://whisperwebfree.com/samples/en-output.vtt) |
| Spanish | [TXT](https://whisperwebfree.com/samples/es-output.txt) | [SRT](https://whisperwebfree.com/samples/es-output.srt) · [VTT](https://whisperwebfree.com/samples/es-output.vtt) |

These are observed model outputs, including recognition mistakes. Compare them with the dataset references above. Results may change with model, backend or settings. This is a reproducible workflow check, not an accuracy or performance benchmark.

A separate 21-minute-1-second synthetic recording, made from the public English clip repeated with silence, completed in five sections. A second run paused after section 1, resumed at section 2 and completed. SRT/VTT exports contained 144 cues with the final cue ending at 20:54. This input was selected through a developer-injected File in a local preview because the native file chooser was unavailable. The synthetic fixture is not a real long meeting or an accuracy benchmark. These tests do not prove the full 1 GB / 1 hour limit. Safari, Firefox, mobile devices, WebGPU and other codecs are not covered. Operating-system download completion was not verified.
