Does Google voice typing use AI?

Yes, in the technical sense. Google's voice typing in Gboard uses a trained neural speech recognizer, and Google has described that recognizer in some detail ¹. The sources checked do not describe a separate language-model step that rewrites your text, so the answer is that Gboard voice typing is AI as a recognizer, and nothing in these sources says it generates new text. Where it runs depends on your phone, which matters as much as the model.

Gboard's recognizer is an all-neural model

In 2019 Google announced an end-to-end, all-neural, on-device speech recognizer to power speech input in Gboard ¹. "All-neural" means the whole recognizer is one neural network, not a chain of separately built statistical parts. That is the kind of trained model behind the claim that speech to text is AI, covered in the overview of speech to text AI.

The model moved onto the phone

The change that made this practical was size. Google's older server recognizer used a search graph of almost 2 GB, which Google said could not easily be hosted on a phone, so it needed a connection ². The on-device model is an 80 MB recognizer ³, a small fraction of that size.

Google said in 2019 that the on-device recognizer is always available, even when you are offline ⁴. The launch was limited, though. It went first to Pixel phones and only in American English ⁵. In February 2025, 9to5Google reported that Gboard for Android features offline voice typing on all devices ⁶. Check the language and device list on your own phone before you rely on offline use.

iPhone is a different case

The Gboard app on iPhone is not the same arrangement as the Android recognizer. Google's App Store listing says voice input from the Gboard microphone is sent to Google for transcription ⁷. So an answer about Google voice typing on iPhone is a cloud answer, even though the Android answer above describes an on-device model. Read the platform before you apply a policy or a privacy rule.

Where the rewrite question stands

None of the Google sources in this guide describe a language-model rewrite in Gboard voice typing. Gboard's help does list spoken phrases that add punctuation, such as period, comma and new paragraph ⁸. Saying "period" to add a full stop is a spoken command. It is a different act from rewriting the sentence around it, and the sources do not describe Gboard rewriting your sentences.

If Google adds a rewrite step, its Gboard help pages are where to look. Use the same three checks as for any tool: look for a named rewrite feature, read the description, and test a sentence with a filler word.

What to do

1. Check your platform. On Android, Google describes the on-device recognizer above, but your phone and language may differ. On iPhone, expect cloud transcription.
2. Check offline support on your device. Languages and phones vary, so test with airplane mode before you depend on it.
3. Test for rewriting. Dictate a sentence with "um" and a grammar error, and compare the output with what you said.

For voice typing in Google Docs on a computer, see the glossary entry on voice typing in Google Docs. Readers who want to know whether a rewrite changes their words should read the guide on AI cleanup for dictation, and compare the Microsoft side. The question on whether voice typing counts as AI explains how policies treat these tools. The guide to on-device speech recognition covers the wider comparison.
