Speech to Text – Voice Notes (Online & Offline) by Mobikul Webkul

Speech to Text – Voice Notes lets you dictate directly into text fields and editors on websites in Firefox. Click the floating microphone, speak, and your words are inserted where you are typing.

Private, on-device dictation
Speech recognition runs locally in your browser. Your audio and transcripts stay on your device.

Choose your speech model

• Whisper Tiny (English): Included with the extension, selected by default, and works offline. It transcribes after you stop speaking.
• Cactus Whistle: An optional 16.9 MB download from the extension settings. It supports English, German, French, Spanish, Italian, Dutch, and Polish. After-stop transcription is the default; choose While I speak for live transcription.

Get started

1. Open a webpage and click in a text field or editor.
2. Allow microphone access if Firefox asks.
3. Click the floating microphone and speak.
4. Whisper Tiny adds the transcript after you stop. For live transcription, download and activate Cactus Whistle in settings, then choose While I speak.

Cactus Whistle needs an internet connection for its initial download. Once downloaded, it also works offline.
