python - 语音识别无法正常工作(未检测到麦克风)

Question

我想用语音识别做一个小程序。

这是我的代码(经典代码):

import speech_recognition as sr
r = sr.Recognizer()

with sr.Microphone() as source:
    print("SAY SOMETHING")
    audio = r.listen(source,timeout=3, phrase_time_limit=3)
    print("TIME OVER")
try:
    print("TEXTE : "+r.recognize_google(audio, language="fr-FR"))
except Exception:
    print("ERROR")

但是，当我尝试启动程序时，出现此错误:

ALSA lib pcm_dsnoop.c:638:(snd_pcm_dsnoop_open) unable to open slave
ALSA lib pcm.c:2565:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear

当我做 arecord -l时，我有这个:

**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC298 Analog [ALC298 Analog]
Subdevices: 0/1
Subdevice #0: subdevice #0

附言:麦克风可以与Skype或Google等任何软件配合使用
