From researching on the internet I have learned that microphones output analog voltages and with the help of amplifiers they can store that variating voltages as digital data in case you want to store that audio.
Anyways I want to wake up Alexa by doing gestures as an alternative. On my phone I have a recording that says "Alexa how is the weather today". I want to send that audio to Alexa so that she responds without me having to talk for purposes of learning. Here is my approach:
disassemble Alexa and find the microphones. There should be 4.
Get an audio cable peal one side of it and solder it to one of the microphones of Alexa. I have a 50% chance of getting this right. I don't know what side of the cable goes to the positive and negative.
Connect the other end of the audio cable to my phone and play the audio on my phone.
If I do this experiment will it work?
I know I can play the audio on my phone to simulate this. I also know I can purchase the Alexa remote control that will wake her up. I am asking this for purposes of learning.
