I do not know a faster way sadly, but I will adjust my streamer to produce mono 
I tried to install rhasspy-hassio-addon and this is log:

Could you help me?
Sure, happy to help. From the logs, it looks like youâre trying to run Rhasspy on a Raspberry Pi (or at least an ARM-based system). The key error is unexpected reloc type 0x03, and is related to snowboy (the wake word component). This appears to be a bug in how they build their library that I canât fix it because they donât provide source code!
To just get things up and running, Iâd recommend using pocketsphinx instead of snowboy for wake word detection. Itâs not as good as snowboy, but it will at least work on all platforms.
I plan to eventually downgrade my Docker base image to something where snowboy will work, but this is not yet possible because of conflicts with some core Rhasspy components. Yay computers.

I installed Hassbian and installed Rhasspy by Virtual Environment
All was well:
but I can not add the hotword_snowboy custom component. Here is log:

How to fix it?
OK, once youâve followed the virtual environment instructions, just run the run-venv.sh script. You donât need any custom components; those are for a much older version of Rhasspy.
The only thing you need to add to Home Assistant are automations to handle the voice commands

SyntaxError: invalid syntax
But I just need a custom component for Home Assistant to record audio just after hotword, and then save it in âconfig/wwwâ folder as you recommend me here.
The syntax error youâre seeing is because Rhasspy requires Python 3.6 (you probably have 3.5 installed).
One way to do what you want is to use the custom components as I described (except you should probably try the hotword_pocketsphinx component instead).
You could also do it with the version with Rhasspy you have installed. The easiest way I can think of is:
- Override the speech to text system with the command system and set
speech_to_text.command.programto something you wrote that just writes the WAV data from stdin to your file (e.g.,cat > /config/www/audio.wav). - Turn off the rest of Rhasspyâs pipeline by setting:
-
intent.systemandhandle.systemtodummy
-
Hope one of these things works

Will try again.
Please see the more recent installation instructions from this repository.
The version of Rhasspy you were trying to install is now deprecated. Iâll try and mark the repos better to make this more clear. Sorry for the confusion.
OK, I added a copy audio example that does what youâre asking. The profile.json file (under rhasspy/profiles/en) sets to speech to text system to command, and has it call a script named copy-audio.sh. This script just saves the recorded WAV data to an output directory inside the profile. Steps 6 and beyond are disabled in Rhasspy.
I added a run-venv.sh script inside the example that will run everything out of that directory. If you want to change the wake word to something besides âokay rhasspyâ, youâll need to edit the profile.json and then re-train. Good luck, and let me know how it goes!
Documentation is as far as I have read it very clear.
I have managed to use my MQTT streamer as well to control a service in Home Assistant. I am rather limited on time, but I liove the work you are doing
Hmm, I still have problems with my MQTT audio recording, it does not seems to be getting any input.
I tried to find it in the could, but could not guite find it.
I have and esp32 Matrix Voice and I am using met streamer to publish messages to the hermes audioFrame topic. This works, but since Rhasspy does not seems to get any voice command I was wondering about the internals.
- the software I use sends 256 frames of 16000, 16bit audio, each in a WAV container as 1 message. This is a continuous stream of lots and lots of small messages.
My question is: Does Rhasspy decode all those message and use the raw audio buffers as recordings or does it work in another way? I can adapt my software, but oneshot is not an option, simply because the esp32 can not send such large buffers due to memory limitations.
I have implemented it so that it works for Snips, but I would like to know what exactly to send per message (wave files? raw buffers? and how many frames?)
Rhasspy expects each message to contain WAV data. For each message, it unpacks the raw audio data from the WAV, converts it to 16-bit 16Khz mono (if necessary), and then generates an internal message that flows around an actor network. I recently added an extra buffer between MQTT and the actor system to ensure that message queues donât get overflowed, which was definitely happening with many small messages.
Iâve uploaded some test WAV chunks to my mqtt example to show you what Rhasspy expects (see this specifically). The shell scripts in there are using my new mqtt command listener to start/stop the voice command. Iâve tested this with the default webrtcvad system too, so you should keep using the default voice command system (unless you do voice activity detection on your esp32âs!).
Excellent thank you, I see the waves are 1004 bytes, which is 960+waveheader.
If I send a waveheader + 512 bytes, should I adjust the chuck_size?
That might become an issue with the 10,20 or 30 ms required for webrtcvad
I will first adapt software to send 960 bytes.
The esp32 is not powerfull enough to do voice activity detection I think, but I would be happy to be proven wrong 
edit: a see a new version released. Will try with the new stuff in it
It should work with 512 bytes without any changes. The webrtcvad component will buffer audio data until it gets at least command.webrtcvad.chunk_size bytes, which it then processes. I havenât tested any other sizes, though.
Assuming 16-bit 16Khz mono, valid values for command.webrtcvad.chunk_size would be 320, 640, and 960 bytes. Not sure why, but webrtcvad is pretty whiny about it

I have done some tests with a separate system, voice detection works pretty good.
I have some trouble with the hotword not being detected though, anyone else having issues with that?
After I manually press the wake button, all is good
I could not get the builded hotword detected to work, so then I tried you Snowboy addon.
Together with setting to wake detection to hermes, this worked pretty well.
I see in you addon you can upload models, but these are not persistant. When I upload a model, change the config to use that model I have to restart the addon. But then the modelfile is removed again, it the addon still under development?
It works fine when I use snowboy, I finally have something working in Dutch
I am using my Matrix Voice to stream audio data via MQTT by the way, all is well
