“Hey Spotify” is how communication with the streaming service may begin in the near future. Then you need to name the artist – and, perhaps, you will hear something from his repertoire.
So far, this works with the proprietary application enabled. If not, you can try going to Settings> Microphone permissions> “Hey Spotify”. This option cannot be called uncontested: Voice access to Spotify features includes Alexa, Siri, Google Assistant, Cortana and Bixby. But a branded service will certainly be capable of more.
The feature is being deployed on Android and iOS devices — it was launched about a year ago. Don’t forget that Spotify’s smart car app called Car Thing also provides “Hey Spotify” as a voice greeting. This became known 2 years ago.
It seems that Car Thing is already close to entering the market. In principle, from the car, a special voice assistant Spotify may well migrate, for example, to headphones designed to work with this particular service.
