How long can the recording be?

Up to thirty minutes per file, and up to 100 MB. For something longer, cut it with the Audio Cutter here and transcribe the pieces.

Which languages does it handle?

Whisper base is multilingual and will usually detect the language on its own. English, Hindi, Spanish, French, German, Portuguese, Arabic, Japanese, Chinese and a number of others are selectable if you would rather be explicit, and there is an option to write the transcript in English regardless of what was spoken.

Why is the first run slow?

It downloads about a hundred megabytes of model the first time, then caches it. The transcription itself is also slower without WebGPU, since the fallback runs on one WebAssembly thread.

Can I get subtitles rather than plain text?

Yes. Alongside the .txt you get .srt and .vtt built from the model's own segment timings, ready to drop into a video editor or a player.

Will the transcript be perfect?

No, and no transcriber is. Names, jargon and overlapping speech are where it slips, so read it through before relying on it. Hindi has also come back correctly worded but in Urdu script, which is a known weakness of a model this size with closely related languages. What it will not do is invent a transcript — if it finds no speech it says so.

Is Speech to Text free to use on ShortTrick?

Yes, Speech to Text is 100% free with no hidden charges, watermarks, daily usage limits, or account registration required.

How to Use Speech to Text Online: Step-by-Step Guide

4 min read•Updated 2026-10-18

Speech to Text listens to a recording you upload and writes out what was said, as plain text and as subtitles with timings. It runs Whisper in your own browser, so the audio is never uploaded.

Quick Summary

A transcript is far quicker to search, quote and edit than a recording. Because the model runs on your own machine, a confidential call or a client interview can be transcribed without handing the audio to anyone.

Best Practices & Key Considerations

Expert Recommendations

About a hundred megabytes of model weights and runtime come down the first time you use the tool, served from this site rather than from a model hub. The browser caches them, so ev
Combine Speech to Text with related ShortTrick audio tools for an end-to-end digital workflow.

Common Mistakes to Avoid

Using unoptimized or damaged source files that trigger parse errors.
Exceeding single-file memory quotas by uploading multi-gigabyte files.
Ignoring configuration presets suited to specific platform requirements.

Troubleshooting & Common Issues

Processing fails or browser tab becomes unresponsive

Possible Cause: Very large files can exhaust available browser tab heap memory during heavy graphics or media decoding.

Solution: Close unused browser tabs, or process files in smaller batches (e.g. 5-10 files at a time instead of 30).

Output format or file extension does not open in third-party viewer

Possible Cause: Certain legacy desktop applications lack codecs for modern formats like WebP, AVIF, or Opus.

Solution: Select standard backwards-compatible export formats like PNG, JPG, or MP3 in the tool settings dropdown.

Quality appears different from expected output

Possible Cause: Aggressive lossy compression or incorrect aspect ratio scaling settings selected in the interface.

Solution: Adjust the quality slider to 85%+ or choose lossless processing mode to retain original fidelity.

Client-Side Processing: Speech to Text runs entirely in your browser memory via HTML5 Canvas / WebAssembly. Your files and data are never transmitted or stored on any remote server.

Frequently Asked Questions

No. The model runs inside the page and the recording stays in the tab. The weights and runtime are served from this site, so no model hub or third party is contacted either.
