…out my new Alexa device from Amazon. It (she?) is always listening for the command prompt, “Alexa.” If a government could demand that Apple and Facebook change their software for higher levels of surveillance and control, why not ask Amazon or Google to modify their in-home assistants? Well, it is kind of happening in 2016. The first subpoena was issued to Amazon asking for information from an Alexa device. It’s not a request to actively record, but watch for that in the future.
So if you are looking for a start-up idea, I wouldn’t recommend trying to build your own speech recognition system to compete with Google. Instead, figure out a way to get people to give you recordings of themselves talking for hours. The data can be your product instead.
