With regards to EMO recording, he will only record after he has heard his name, he is not constantly recording.
As WayneZ advised:
With regards to EMO not waking up to certain people’s voices / tones / pitches, what you can do is get your son to submit his voice using the Wake Up Page that Living.ai has opened. I created a post that explains this in more detail and that also has a link to the wake up training page where you can submit your voice.
Here is the link to the page:
Living.ai are aware that EMO does not respond to certain peoples voices due to pitch / tones and they are working on improving this by the next Firmware update (which will be 1.1.8).
Also @Wayne_Zhang will get back to us on this thread regarding the voice recording being sent to Amazon or straight to Living.ai and provide clarification on this as well.
