Dictation in Gemini
Voice dictation in Gemini for research prompts, follow-ups, and content briefs
The quality of Gemini's answer depends on how much context you give it. Speaking a long prompt is faster than typing it, and with SnailText the transcription and cleanup both run on your machine.

AI dictation in Gemini, on your device
SnailText is AI dictation: a speech model turns your voice into text, then a second model cleans it up, dropping filler, fixing punctuation, and matching the style your work needs. Both models run on your own machine, so nothing you say in Gemini is uploaded for transcription. Press the hotkey, speak, and the finished text lands at your cursor.
Does Gemini have built-in dictation?
Gemini has a mic in the prompt box on both desktop and mobile, but it is tuned for short prompts and tends to stop listening on a pause, often cutting off long dictations after a few hundred words. It also only works inside Gemini. SnailText keeps recording until you stop, runs an LLM cleanup pass locally, and works in every other app too.
Speech to text in Gemini: how it works
SnailText does not plug into Gemini directly. It runs system-wide: a global hotkey (Option+Space (Mac) / Ctrl+Space (Windows), customizable) starts recording, the local speech-to-text engine (Whisper or Parakeet) transcribes what you said, and the text is pasted at your cursor through the system clipboard, the same way it lands when you type. That means it works in every Gemini field, plus every other app on your Mac or Windows machine, with no extension or integration to set up.
That matters in Gemini specifically: typing a long, detailed prompt is slow, and the answer is only as good as the context you put in. Speech to text removes that bottleneck without changing how you work in Gemini.
Voice to text in Gemini: what to dictate
Voice typing in Gemini is not limited to one box. Press the hotkey anywhere a cursor blinks and your speech becomes text, so the things you would normally type out by hand become things you just say.
- · Long research and analysis prompts with multi-paragraph context
- · Follow-up clarifications and refinements to a previous answer
- · Your own rough notes, dictated in, then handed to Gemini to restructure
- · Content briefs and outlines you want Gemini to expand
Where typing slows you down in Gemini
- · Typing a long, detailed prompt is slow, and the answer is only as good as the context you put in.
- · Gemini's mic tends to be locked to one language and struggles with code-switching, so non-English or mixed-language prompts come out wrong.
- · The native mic is built for short prompts and stops on a pause, so a long dictated prompt gets cut off partway through.
