Alexa Skill Testing Tool - Echosim.io. Interested in Amazon Echo and Alexa; but, want to try it out first? Go here and you can take her for a dry run. The Music function doesn't work; but, you can get a feel for what it is like to talk to Alexa and ask the time, or whatever. Have fun. You need an Amazon account to use the site; but, who doesn't have an Amazon Prime account these days?
