Python: 在语音识别中获取系统音频而不是麦克风

Question

我正在 python 中进行语音识别，但它只能从 Micropohone 获取输入。如何将扬声器的音频作为语音识别库的输入？

代码如下：

import speech_recognition as sr
with sr.Microphone() as source:   # using microphone here, would like to use speaker instead
    print("Talk Something...")
    audio=r.listen(source)
    print("Time Over...")

import time
try:
    t1=time.time()
    print("Text: "+r.recognize_google(audio))   # prints after converting speech to text
    t2=time.time()
    print("T2-T1: ", t2-t1)
except:
    print("Didn't understand the audio")

我在这里苦苦挣扎了很长时间，非常感谢任何帮助。谢谢！

您可以配置设备索引，如docs:

import speech_recognition as sr
for index, name in enumerate(sr.Microphone.list_microphone_names()):
    print("Microphone with name \"{1}\" found for `Microphone(device_index={0})`".format(index, name))

如果 LINEIN 不能作为单独的输入，您可以在音频属性中将其配置为录音源。
