Hi, the bot works perfectly for the first two chunks (10 seconds), however it returns nothing after that point. I've written the audio chunks to wave files, and after the first 2 chunks there's just a weird constant whine that's unaffected by the actual discord voice.

is it possible to use vosk now as it can generate a fsater response. google works like a grandma

AttributeError: module 'discord' has no attribute 'reader'

i get this error. do you know how to fix it ?

To get voice support, you should use discord.py[voice] instead of discord.py.
installing discord.py

Same issue here that iHazzu lists. Using anaconda in an anaconda created environment. Using python 3.10. Installed in the activated environment with pip install -U discord.py[voice].

Same here using a virtual environment using discord.py[voice]

I guess the used library of Discord.py is outdated because for example there doesn’t exist a class discord.reader.AudioSink anymore. You can read it in the Discord.py docs: https://discordpy.readthedocs.io/en/stable/api.html
