Now that Google Assistant has 8 english voices to choose from, the company is rolling out a colorful update that gives US users a new interface for changing Assistant’s voice. According to Google, You just select a color associated with a random voice.
The update should be platform-agnostic and will be widely available in the US by the end of the week. It’s not certain how screen readers will interpret the colors or when other countries will receive the new interface, but that’s also dependent on having multi-voice support in your region.
