python - 麦克风之间的 Python 语音识别变化

问题描述

通过运行以下代码，我得到了所有可用的麦克风：

import speech_recognition as sr

for index, name in enumerate(sr.Microphone.list_microphone_names()):
    print(f'{index}, {name}')

这些是我拥有的所有麦克风（和其他东西）：

0, Microsoft Sound Mapper - Input
1, Microphone (Realtek(R) Audio)
2, Stereo Mix (Realtek(R) Audio)
3, Microsoft Sound Mapper - Output
4, Speakers (Realtek(R) Audio)
5, Primary Sound Capture Driver
6, Microphone (Realtek(R) Audio)
7, Stereo Mix (Realtek(R) Audio)
8, Primary Sound Driver
9, Speakers (Realtek(R) Audio)
10, Realtek ASIO
11, Speakers (Realtek(R) Audio)
12, Stereo Mix (Realtek(R) Audio)
13, Microphone (Realtek(R) Audio)
14, Speakers 1 (Realtek HD Audio output with SST)
15, Speakers 2 (Realtek HD Audio output with SST)
16, PC Speaker (Realtek HD Audio output with SST)
17, Microphone 1 (Realtek HD Audio Mic input with SST)
18, Microphone 2 (Realtek HD Audio Mic input with SST)
19, Microphone 3 (Realtek HD Audio Mic input with SST)
20, Stereo Mix (Realtek HD Audio Stereo input)

如何选择特定的麦克风进行语音识别，我需要在索引 1 和 2 的麦克风之间交换以进行测试我该怎么做。

参考代码：

import speech_recognition as sr

r = sr.Recognizer()
with sr.Microphone() as source:
    print("Speak Anything!")
    audio = r.listen(source)

    r.energy_threshold = 300
    r.pause_threshold = 1

    try:
        text = r.recognize_google(audio)
        print("You said : {}".format(text))
    except:
        print("Sorry could not recognize what you said!")

有没有办法打印当前正在使用的麦克风？

解决方案

利用

mic = Microphone(device_index=1)

完整代码：

import speech_recognition as sr

r = sr.Recognizer()
mic = Microphone(device_index=1)
with mic as source:
    print("Speak Anything!")
    audio = r.listen(source)
