The thing about trigger words and context understanding is that there is no need to integrate with Alexa. You can simply use a different trigger word, and all will be well. For many products that might even be desirable behavior. Lights ! Versus "Alexa turn on the lights". Plus it means no integration necessary, which won't exist for many products anyway. Also these are very cheap algorithms to run. A trigger word implementation is a one-word vocabulary GRU RNN. Does something like 2000 multiplications every second. Easily in microcontroller reach, for power budgets measured in milliamps. Actual word recognition perhaps isn't but the microcontroller can just constantly record, and when it sees a trigger send it on. So you could have 20 projects in the house, all listening to your voice, and it wouldn't really affect the electricity bill.
