A:Answer Thank you for your question, DJ. The microphone in the SoundLink Revolve speaker acts as an extension of the microphone in your smartphone. Using on the speaker, you can access the voice controls capabilities on your mobile device to make/take calls or ask Siri or Google to play music, tell you the weather, and more. You can press and hold the multi-function button to access voice control on your device. We hope this helps. Ashley - Bose Support
