| If you're less concerned about privacy, I use Gemini 2.5 Flash for this and it's exceptionally good and fast as a HA assistant while being much cheaper than the electricity that would be needed to keep a 3090 awake. The thing that kills this for me (and they even mentioned it) is wake word detection. I have both the HA voice preview and FPH Satellite1 devices, plus have experimented with a few other options like a Raspberry Pi with a conference mic. Somehow nothing is even 50% good as my Echo devices at picking up the wake word. The assistant itself is far better, but that doesn't matter if it takes 2-3 tries to get it to listen to you. If someone solves this problem with open hardware I'll be immediately buying several. |

| How about a button? I'd prefer to physically press a button on an intercom box than having something churning away constantly processing sound. |
| |
| ▲ | hamdingers 6 hours ago | parent | next [-] | | If I have to go to a thing and push a button, I'd rather the button do the thing I wanted in the first place. Voice assistants are for when my hands are full or I don't want to get up. (I wrote more about my home automation philosophy in another comment[1]). Also I have all my voice assistant devices mounted to the ceiling 1. https://news.ycombinator.com/item?id=47399909 | |

| ▲ | CurleighBraces 3 hours ago | parent [-] | | Did you have any luck with the power issues on the new board? | | |
| ▲ | stavros 3 hours ago | parent [-] | | 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. | | |
| ▲ | CurleighBraces 2 hours ago | parent [-] | | 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! | | |

| What's been surprising in my experience regarding the wake word is that it recognizes me (adult male) saying the wake word ~95% of the time. However, it only registers the rest of my family (women and children) ~30% of the time. |

| ▲ | vineyardmike 4 hours ago | parent [-] | | I have no firsthand knowledge, but I’d strongly bet that the home-assistant effort to donate training data is mostly get adult males, and nearly zero children. | | |
| ▲ | bluGill 10 minutes ago | parent | next [-] | | I remember when those systems first started collecting data they were worried kids wouldn't be handled - but they didn't know how to handle the privacy issuses with recording kids so discouraged it. Women being missed is not a surprise - but not anticipated. | |
| ▲ | dghlsakjg 3 hours ago | parent | prev | next [-] | | This was 2021 (so pre-llm), but I used to work for a company that gathered data for training voice commands (Alexa, Toyota, Sonos, were some clients). Basically, we paid people to read digital assistant scripts at scale. Your assumptions about training data do not match the demographics of data I collected. The majority of what our work revolved around was getting diversity into the training data. We specifically recruited kids, older folks, women, people with accented/dialected English and just about every variety of speech that we could get our hands on. The companies we worked with were insanely methodical about ensuring that different people were included. | | |
| ▲ | gmueckl 2 hours ago | parent [-] | | You are reporting on a deliberately curated effort vs. what I understand is effectively voluntary data donation without incentives. It's not surprising to me that the later dataset ends up biased due to the differences in sourcing. |
| |
| ▲ | ethagnawl 4 hours ago | parent | prev [-] | | Oh, I'm sure you're right. I've had people in my personal life (non-technical; "AI enthusiasts") laugh at me over concerns about training bias but this is likely a real world example of it. | | |
| ▲ | stavros 3 hours ago | parent [-] | | I think you can train your own wake word with microWakeWord but I've never done it. |

| I have a feeling beamforming microphone arrays might help here, something like this could improve the audio being processed substantially - https://www.minidsp.com/products/usb-audio-interface/uma-8-m.... |
| |
| ▲ | ethagnawl 4 hours ago | parent | next [-] | | That's a good call. I have a PS3(?) mic/camera that I was using when I was running the original Mycroft project on a Pi. I wonder if that would help with the inbuilt HA mic not waking for most of my family, most of the time. I will have to look at my VA Preview device and its specs later because I'm not sure if you can connect an external mic to it out-of-the-box. | |
| ▲ | IshKebab 6 hours ago | parent | prev [-] | | Alexa devices have these (or used to at least), but Google Home's never did. So it shouldn't be necessary. | | |
| ▲ | jcims 5 hours ago | parent [-] | | Yeah a small (ideally personalized) wakeword model would probably outperform just about any audio wizardry. |

| Why not use an easier to detect wake “word”, like two claps in quick succession? Or a couple of notes of a melody? |
| |
| ▲ | hamdingers 6 hours ago | parent [-] | | Can't clap if your hands are full and I would not subject my family to my attempts at delivering a melody. I haven't tried training my own wake word though, I'm tempted to see if it improves things. | | |
