The pebble index seems like the optimal form for this. https://repebble.com/index https://repebble.com/index Could be pressed even if your hands were busy.

If you want to relax some constraints, I made something similar for $10: https://www.stavros.io/posts/i-made-a-voice-note-taker/ https://www.stavros.io/posts/i-made-a-voice-note-taker/

  Did you have any luck with the power issues on the new board?
  - stavros 7mo ago
    The new board hasn't come yet, but a friend gave me a great idea, to power the mic from a GPIO, which powers it off completely when the ESP is off. Hopefully the new boards will be here soon, but another issue is that I don't really have anything that can measure microamp consumption, so any testing takes days of waiting for the battery to run down :( I do think these clones are the issue, though. They had a LED I couldn't turn off, so they'd literally shine forever. They don't seem engineered for low quiescent current, so fingers crossed with the new ones.

      Makes a lot of sense :) thanks for the update. I'll try to remember to creepy stalk you for updates as the device sounds great!

        Thank you for the blog/updates. Since you're deep into this space, Do you use wall mount dashboards? There seems to be two camps now: Dashboards everywhere or none at all.

      Is it worth removing the led from the board? Wont help with any other decisions by the designer that draw excess current, but maybe that's the only or largest one?

        I did remove it :( It's still pretty bad. I ordered some Xiaos that do explicitly say 14 uA sleep current, but they seem to have gotten lost in the mail!

Most of what I (and in my experience many people) want a voice assistant for, is setting+ending timers... which for me happens mostly in the kitchen, while I'm simultaneously holding a hot pan or hand-tossing a salad or paper-towelling off some raw chicken. In none of those cases would I want a ring anywhere near my hands, let alone a smart ring. (And nor, in half of those cases, is it convenient/hygenic to use my oven timer.) That being said, we could solve for fully 50% of in-home voice-assistant use-cases just by developing an extremely domain-specific voice assistant that has an extremely small (ideally burned-into-a-DSP) voice model that only knows how to recognize commands to manage kitchen timers. If such a device existed, and was cheap enough that you could assume anyone who wanted this functionality would just buy one, then this would make truly hands-free activation of a "real" voice-assistant much less necessary, as there'd be far fewer user-stories that would really "need" that. The rest of those user-stories really mostly could work with some kind of ring / belt buckle / shirt comm badge / etc.
