I'm an app developer and I just launched an app that allows users to control their Spotify player through voice commands. I'm looking for feedback on the product, so if you went to https://play.google.com/store/apps/details?id=com.tmacstudios.spotifyvoice downloaded the app, used it, and gave me feedback, I would greatly appreciate it.
The app's primary use is for when your hands are tied but you need to change songs. For example, say you're driving and you want to listen to another artist. Rather than taking your hands off the wheel, you can prompt the app by speaking and tell it which band to switch to. Alternatively, you can prompt it by clicking the sleep button - the app will automatically lower the music so it can hear the command you say, and then it will change the playing band.
