There are now a few apps which put alexa on your phone. I've been playing with an app called "Lexa" which is similar to the others. I've just created a tasker task which loads the app and presses the button automatically to make her listen afterwards. I have saved it as an app via tasker and mapped it to my phone home button, so a double tap of the home button is all you need to do to speak to alexa anywhere. Works well in the car, especially for it reading my kindle books to me. I'm hoping music will work on it soon too. It controls all my home automation stuff too, which is a billion times quicker now for turning on the heating when heading home in winter than loading the stock app for Wemos or hue etc etc. Just double tap and "turn on the heating"! Great!
