After many months and hundreds of hours of work, I am sharing a video of the final prototype before moving into the final shell design and manufacturing.
In the video, I am using an IR sensor that gets activated by the flash from my phone, to simpliy the recording process, as normally it would require an actual wrist flick.
Moreover, in the second part of the video, I am using multiple times the voice command "Thanks for the info provided", so that I can demonstrate the random "How can I help you today" voice line with the different 10 alternatives available, as well as the output "You are welcome" voice line, which has 6 different alternatives.
