Any advices to get it work properly?

[MoleHoleDev]

Hello, I already installed every lib and all dependencies and almost got it working, but It looks like mine bender recognizes random words. Looks like I need to do some configurations with amixer because it can't find any simple controls.
Im skipping mpc cuz its just music player as I think, and also errors with permissions to backlight, this will be not a much problem, but recognizing and responding is most valuable :)
Im asking you very kindly to help me with this, here my log via ssh:

Hello!
Yes, it's probably could be a problem with sensivity of the microphone.
Have you installed alsamixer? As I remember I lowered "Gain" control on the Mic(I'll check later).

[MoleHoleDev]

Hello, alsamixer is installed, it seems like I have problems with pulse audio.
Just added
nano ~/.asoundrc

defaults.pcm.card 1
defaults.ctl.card 1

but with, same result.

Where I can reduce "mic gain"?

---

Edit:
In speech_recognizer.py: I uncommented + ' -remove_noise yes' with changing no to yes
In volume_control.py: changed "mixer -q -c 1 set "

Now im able to recognize some words like "reboot", "shutdown" or "turn off the blue light" but with low accuracy(saying: "turn on the green light")

[sindar]

Well, it's the trickiest part with accuracy:) It depends on the ambient sounds, how close you're talking to, etc. I helped one guy with the same problem, it was really hard to get it work.
