Custom Google Assistant voice: what works on Android
Many people want their phone’s assistant to sound like Jarvis, Darth Vader or someone they love. The honest answer: Google Assistant and Gemini speak only in Google’s own voices, and you cannot add a custom or character voice to them.
Android is more open in other places, though. Alarms, ringtones and notification sounds can be any audio file, so a character voice can still greet you every morning. This guide shows what Google allows and how to do the rest.
What Gemini and Google Assistant allow
In the Gemini app, tap your profile picture, then Settings and Gemini’s Voice, and swipe through the voices; Google notes that the choice differs by language. Google Assistant has its own set of voices, named after colors, in the Assistant settings. Neither lets you add other voices.
A character voice for your alarm
Voice a wake-up line on the Jarvis (ENG) page or any other voice page: type 30 to 100 characters, press Voice it and download the clip, with no account. In the Google Clock app, open the alarm, tap its sound, choose Your sounds and add the file. Our alarm voice guide has more ideas and steps for other phones.
Ringtones and notification sounds
The same clip, or a shorter one such as “Sir, you have a new message.”, can be your ringtone or notification sound. Most Android phones let you add an audio file in Settings, Sound, Ringtone, and pick a sound per app in its notification settings; if the file is not listed, copy it to the Ringtones or Notifications folder. Our name ringtone guide shows ringtones per contact.
Many lines at once
For a set of sounds, install the free engine with python -m pip install superclonica-cpu and voice each line from a text file. Jarvis, Darth Vader, Optimus Prime and every other catalog voice work the same way. Character voices are fan-made, not the original actors, and are meant for personal fun like this.
