python - 我的麦克风不适用于谷歌识别器

Question

当我运行这段代码

import speech_recognition as sr
listner=sr.Recognizer()
try:
  with sr.Microphone() as source:
    print("listening.....")
    voice=listner.listen(source)
    command=listner.recognize_google(voice)
    print(command)
except:
  pass

会得到这种类型的错误：

• ALSA lib pcm_usb_stream.c:486:(_snd_pcm_usb_stream_open) 卡类型无效
• ALSA lib confmisc.c:1281:(snd_func_refer) 找不到定义 'cards.bcm2835_hdmi.pcm.iec958.0:CARD=0,AES0=6,AES1=130,AES2=0,AES3=2' ALSA lib conf。 c:4568:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory
