linux - PyAudio 打印 ALSA 警告并且不起作用

Question

我正在尝试运行一个基本的 python 语音到文本代码。这是代码。

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")

代码在到达打印阶段之前工作正常，然后抛出此错误。我做错了什么吗？

Answer 1

如果有人还在寻找摆脱

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

我刚刚在“PCM 接口(interface)”部分注释掉了所有 pcm.surround* 行

/usr/share/alsa/alsa.conf

文件，它对我来说很好用。
