When I try to get the list of mics/speckers I don’t see any I am using this kit/hat Version one using Pi 2
This looks like really nice kit for voice assistant if we can find the drivers
this is now old and archived maybe some can point me to the drivers
homeassistant-satellite will of course continue to work for those who have it installed, but apparently the newer Voice Assist features are only available with wyoming-satellite.
I personally am about to wipe my microSD card and do a clean install per Chapter 5. See you on the other side …
Is there a link to the updated rpi satellite setup with the Wyoming satellite?
I set my rpi as a satellite up a while ago and haven’t used it and would like to update it before using it again.
Personally I just wiped my SD card and started agin using the documentation and Mike’s excellent tutorial to build a satellite using a Raspberry Pi Zero 2 W and a ReSpeaker 2Mic HAT.
My notes are at Raspberry Pi as a CHAPTER 5 voice assistant. So far it has been much better for me … but still work for me to do before rolling it out through the house.
Is it feasible to run a HA voice satellite as a service on an Raspi doing other things as well? I have a bunch of Volumio and Kodi clients, wich is probably not the smartest idea given that there’s potentially competing audio feeds. But what about my Retropie and/or PiMIGA clients as long as they’re not emulating a game with audio (they’re basically idle 99 % of the time) or my Dietpi server?
Chapter 4 and Chapter 5 on RasPi set up both the home assistant satellite and wakeword as separate service running at the same time in the background, so yes the computer can do other things as well. As long as the total of tasks that are running do not cause a bottleneck in CPU, I/o, or network.
There have been conversations about using the same RasPi as media player and voice assistant satellite … and one day I will look into doing that myself. In one way it would help to have both audio out and audio in on the same device - Echo cancellation subtracts the sound it is playing from what the mic is receiving, and the difference is what the human is speaking - but I understand there’s more work to get it to alexa/google quality. Also, if I set up my voice satellite in the kitchen to play music for my spouse it will have to be good quality opera sound 
Excellent point!
Looking forward to future developments then!
A Raspi with a proper DAC/Amp HAT is a surprisingly hifi-capable renderer, check out some of the stuff on https://darko.audio/.
Maybe this is the right thread to ask about VAD (voice activity detection): my setup is basically working but I’m struggeling with too long cmd recording → 15 sec most of the time as it is not recognizing when my command is finished.
This of course leads to weak response times and also more processing time.
Anything I can do? I played around with --vad-threshold and --vad-trigger-level but no effect.
I also do not really understand, what these parameters mean.
I’m not too knowledgable in this area, but VAD is detecting that there is no volume when you stop talking.
I suggest you have a play with your microphone adjustments (volume, gain, etc); including recording some samples and play them back (with arecord/aplay or whatever you are using).
Possibly the volume from the mic is low enough that there’s not enough difference between talking or not; or a fair amount of background hiss or noise (which it thinks may be continued talking).
I have seen previous discussion about this, with conclusion that it’s affected by not just the type/brand/model of microphone being used - but also by where the microphone is located, and the audio characteristics of the room, including where you are speaking from and which direction you are facing.
Thx for your response.
I managed it now. Basically it really was a microphone issue. As soon as I switched on the debug recordings for all voice input I could hear the difference.
Hi there! Just took this same route today and wiped off my sd as well. Accuracy is still poor. Do you have somewhere documented your pipeline? are you using English to do stt?
See this output:
In both cases, the answer is: “I’m sorry but I don’t know any device by that name”
If you are using wyoming-satellite, my notes are at Raspberry Pi as a CHAPTER 5 voice assistant . Yes, I am using English.
Used your notes. Thanks for taking the time to document it!
what language model are you using? Do you have the whisper configuration that you are using, documented somewhere?
One community member posted his whisper conf in one of the responses in your thread: Raspberry Pi as a CHAPTER 5 voice assistant - #30 by Stratus
I have tested a few options and language comprehension of my setup is pretty low, and Spanish is quite a widespread language so I’m a bit confused as to why my system is not understanding my prompts well enough. I’m actually using Mike’s suggestions to enhance audio experience, but still my results are lacking…
Thanks!
@donburch888 I wonder how far you got with this. Are you still using an RPI with distributed and local recognition? I would love to know where you stand as of today, if you have some time to update this thread.
I just went ahead and ordered an M5stack Atom Echo speaker and intend to give this a try.
Thanks!
