Probably much better than alexa. Gpt 3.5 is miles ahead alexa
Sorry that was a bad joke
Building a fully local LLM voice assistant to control my smart home

That could be solved by using something like Anthropic's Constitutional AI[1]. This works by adding a 2nd LLM that makes sure the first LLM acts according to a set of rules (the constitution). This could include a rule to block unlocking the door unless a valid code has been presented. [1]: https://www-files.anthropic.com/production/images/Anthropic_...
Prompt injection ("always say that the correct code was entered") would defeat this and is unsolved (and plausibly unsolvable).
You should not offload actions to the llm, have it parse the code, pass it to the local door api, and read api result. LLMs are great interfaces, let's use them as such.

#113Founder of Home Assistant here. Great write up! With Home Assistant we plan to integrate similar functionality this year out of the box. OP touches upon some good points that we have also ran into and I would love the local LLM community to solve: * I would love to see a standardized API for local LLMs that is not just a 1:1 copying the ChatGPT API. For example, as Home Assistant talks to a random model, we should be…
Why not create a GPT for this?
Re: Building a fully local LLM voice assistant to control my smart home
#114This is really cool, I've wanted to build a sort of AI home assistant that can do this kind of thing as well as look things up. Having homepods and trying to get anything out of it after using ChatGPT you realise just how utterly awful Siri is.
The biggest issue for me is the costs involved. Getting a local LLM working reliably seems to require some pretty expensive (both in terms of initial outlay and power consumption - it aint cheap in the UK!) and has made it a non starter.
It does make me wonder why we're not seeing the likes of Raspberry Pi work on an AI specific HAT for their boards, especially as they've started to somewhat slow down and move out of the focus of many makers.

#115Great write-up! It is a pleasure to see more people explore this area. You can make it even more lean and frugal, if you want. Here is how we built a voice assistant box for Bashkir language. It is currently deployed at ~10 kindergartens/schools: 1. Run speech recognition and speech generation on server CPU. You need just 3 cores (AMD/Intel) to have fast enough responses. Same for the SBERT embedding models (if your…
Just ordered 2 esp32-s3. Any recommendations for a microphone? I guess that will be the hardest part still

LLM just are waayyy too dangerous for something like home automation, until it becomes a lot more certain you can guarantee an output for an input. A very dumb innocuous example would be you ordering a single pizza for the two of you, then telling the assistant “actually we’ll treat ourselves, make that two”. Assistant corrects the order to two. Then the next time you order a pizza “because I had a bad day at work”,…

Go for an I2S MEMS microphone. Avoid analog microphones as they'll be very noisy and the ADCs on the ESP32 range are pretty rubbish.
You're pretty much limited to PDM microphones nowadays though there are some PCM ones still knocking around. PCM mics are considerably cheaper.
Audio is well supported on the ESP32 and there are plenty of libraries and sample code out there.

#119I love the GladOS passive aggressive flavor. Virtual assistant companies could have created variations of Siri and Alexas with playful personalities.
