Spotify has begun rolling out the own wake word. Users can now simply say “Hey Spotify” followed by their artist, album, or song request.
Spotify having its own wake word sets it apart from other music streaming app. although it may seem redundant because you can simply use Google Assitant, Siri, or Alexa for a hands-free Spotify experience.
If you’re one of those people that are concerned about privacy, Spotify states in the privacy policy that it only holds recordings of the wake word and your voiced search.
