As previously suggested, Spotify has implemented a voice assistant to its app. This option was introduced in the application for iOS and Android.
This function allows you to turn on a given list, album or song by saying the appropriate voice command, starting with the words Hey Spotify. Note that this option only works when the application is active on the screen. It should be mentioned that from 2019, users of the website in the Premium version could use voice search, but it required pressing the appropriate button. However, now it can be done with the help of voice commands.
The option is slowly appearing for more customers, if you have not received it yet, it should be available in the next few days. To activate it, go to the application settings, select Voice Interactions and activate Hey Spotify.
