Pandora today announced the launch of its own, in-app voice assistant which you can call up at any time by saying “Hey Pandora,” followed by a request to play the music or podcasts you want to hear. The feature will allow you to not only control music playback with commands to play a specific artist, album, radio or playlist, but will also be capable of delivering results customized to you when responding to vague commands or those related to activity or mood. For example, you’ll get personalized results for requests like “play something new,” “play more like this,” “play music for relaxing,” “play workout music,””play something I like,” and others.

The company reports strong adoption of its service on voice-activated speakers, like Amazon Echo devices, where now millions of listeners launch Pandora music by speaking – a trend which inspired the move to launch in-app voice control.
