Is there a dictation extension for Gmail?

Yes. Chrome extensions add dictation to Gmail. Two that we found in the Chrome Web Store say so in their listings, and one of them puts a microphone button inside the compose window. Among the routes we checked, extensions are the only ones that put a microphone control inside Gmail itself. The trade-off is that an extension runs inside your email, so you should check who made it, how recently it was updated and where its speech is processed before you give it access. Your computer's own dictation also types into Gmail, with no extension and no page access, so it is worth trying first.

Two Chrome extensions name Gmail in their store listings

Dictation for Gmail's listing says you open a new message, or reply to an existing one, then click the microphone icon to the right of the Send button ¹. Voice In's listing says it provides voice typing in ChatGPT, Gmail, Google Docs and more than 10,000 sites, in 50 or more languages ². Both are the developers' own descriptions, so test them on a short draft before you rely on them for real mail.

Check the rating, the last update and the declared data before you install

Store listings give three signals that are easy to check. Dictation for Gmail's listing shows an average of 3.0 out of 5 from 274 ratings ³, which is middling and worth reading the reviews for. Its Details panel shows version 1.0.14, updated on January 1, 2025 ⁴, so the extension may not have changed for a long time. Its privacy section says the extension handles personally identifiable information ⁵.

These are signals, not verdicts. A middling rating can come from one bad update, and an old date can mean a stable tool. Use them to decide whether the extension is worth a short test, and do not treat them as proof of how it behaves.

An extension runs inside the page, so it can read what you write

Chrome says content scripts are files that run in the context of web pages ⁶. A Gmail extension that puts text into the compose box and places a microphone beside Send therefore runs inside the page you write in, so it can reach the email as you write it. Read the developer's privacy policy, and prefer a tool that states where your audio and text go.

Speech may be processed on your computer or on a server

Extensions can use the browser's speech recognition. MDN says that on some browsers, including Chrome, speech recognition on a web page uses a server-based engine, and the audio is sent to a web service ⁷. Chrome 139 added on-device recognition to the Web Speech API ⁸, so the answer depends on the browser version and on how the extension is built. Look for a statement about on-device or cloud processing in its listing or privacy policy, and if there is none, assume the audio is sent to a server.

For work email, check with your administrator first, since an organization may block extensions.

The built-in routes cover most people without an extension

Apple says that with Dictation on a Mac you can speak to enter text anywhere you can type ⁹, so it works in the Gmail compose box with no extension. Google Docs voice typing is another route. You dictate into a document, check the text, and paste it into the draft, which keeps the extension out of your mail entirely. The question on whether Gmail has voice typing sets out each route, including Windows and Android.

What to do

1. Try the built-in route for your computer first. If it works, you do not need an extension.
2. If you want a microphone button inside Gmail, read the extension's store listing: the rating, the last update date, the declared data handling and the description of how it works.
3. Check how the extension processes speech, and if its privacy policy does not say, assume the audio goes to a server.
4. Test it on a short, non-sensitive draft before you use it for real mail.
5. Remove the extension when you stop using it, so it does not keep access to your Gmail tab.

Yap, which we make, is an on-device dictation app for Mac and Windows that types into the field that has focus, Gmail included, and it does not need a Chrome extension to do that. It is one option, and the built-in routes above may be enough. For the wider picture of dictating into any app, see how to dictate into any app.
