You can’t change Google Assistant’s voice to JARVIS from Iron Man, and you can’t rename it or use “Jarvis” as a wake word. Google only offers its own set of voices, labeled by color. What you can do is pick the Assistant voice you like best in Assistant settings > Assistant voice & sounds, change what Assistant calls you, and set up Routines with custom replies to get a bit of that personal-assistant feel. On many newer Android phones, Gemini has replaced Google Assistant and has its own voice options.
How to change Google Assistant’s voice
- On your Android phone, say “Hey Google, open Assistant settings,” or open the Google app, tap your profile picture > Settings > Google Assistant.
- Tap Assistant voice & sounds.
- Tap each color to hear the voice, and choose one. Some voices are British English or other accents.
For a JARVIS-like feel, try one of the British English voices by changing the Assistant language to English (United Kingdom) in Languages, then picking a voice.
If your phone uses Gemini instead
- Open the Gemini app and tap your profile picture > Settings.
- Look for Gemini’s voice (or voice settings under Gemini Live) and choose from the available voices.
Gemini voices use their own names, and none of them imitate movie characters.
Make Assistant feel more like JARVIS
- Change your nickname: In Assistant settings, tap Your name or Nickname and set it to “Mr. Stark” or anything you like. Assistant uses it when talking to you.
- Create a Routine: In the Google Home app, create a Routine that starts with a phrase like “Good morning, Jarvis” and responds with weather, calendar, and news. You still need to say “Hey Google” first.
- Add a custom reply: Some Routines let you add an action where Assistant says a custom phrase.
What about third-party JARVIS apps?
Apps and launchers in the Play Store that promise a JARVIS voice or wake word are unofficial. They don’t replace Google Assistant, may request broad permissions, and often stop working after Android updates. Be cautious about what access you give them.

Frequently asked questions
Can I change “Hey Google” to “Hey Jarvis”?
No. Google Assistant only responds to “Hey Google” or “OK Google.”
Does Google offer celebrity voices?
Google previously offered limited-time celebrity voices, like John Legend’s, but they were retired. No movie character voices are available.
Can I change the voice on a Google Nest speaker?
Yes. The voice you choose in Assistant settings applies to your Nest speakers and displays linked to the same account.
