PyAudio打印ALSA警告并且不起作用 [英] PyAudio prints ALSA warnings and does not work

问题描述

伙计们，我正在尝试对文本代码运行基本的python语音.这是代码.

hey guys i'm trying to run a basic python speech to text code. This is the code.

import speech_recognition as sr
r = sr.Recognizer()
with sr.Microphone() as source:                
audio = r.listen(source)                   

try:
   print("You said " + r.recognize(audio))     
except LookupError:                            
   print("Could not understand audio")

代码可以正常工作，直到到达打印阶段，然后引发此错误.我做错了什么吗?

The code works fine till it reaches the print stage and then throws this error. Is there anything that i have done wrong?

推荐答案

如果有人仍在寻找摆脱的机会

if someone is still looking for getting rid of

ALSA lib pcm_route.c:867:(find_matching_chmap) Found no matching channel map

我刚刚注释了"PCM接口"部分中的所有pcm.surround *行

I just commented out all pcm.surround* lines in "PCM interface" section in

/usr/share/alsa/alsa.conf

文件，对我来说很好.
