Bose speakers with voice activation features use Amazon's Alexa or Google Assistant to allow you to use voice commands to control the speaker. Some Bose speakers, like the Bose Home Speaker 500, have built-in voice control and can be used with Amazon Alexa or Google Assistant without the need for a separate device. Other Bose speakers, like the SoundLink Revolve+, can be used with voice control when paired with a separate device that is equipped with Amazon Alexa or Google Assistant, such as an Amazon Echo or a Google Home.
