通过任何方法都无法通过speech_recognition python获取音频？

Question

我正在尝试让

SpeechRecognition 3.8.1

听我的声音四天。我已经在互联网上看到了以下内容：

1. https://github.com/Uberi/speech_recognition/issues/20
2. https://www.geeksforgeeks.org/voice-assistant-using-python/
3. https://pythonrepo.com/repo/Uberi-speech_recognition-python-audio

   • sudo apt-get install python-pyaudio python3-pyaudio

     对我不起作用。
4. 语音识别Python代码不起作用
5. Visual Studio 代码 Python 上的 PyAudio 错误
6. 我无法在 Windows 上安装 pyaudio？如何解决“错误：需要 Microsoft Visual C++ 14.0”？
7. https://stackoverflow.com/questions/50424902/speechrecognition-python-package-does-not-listen?r=SearchResults&s=4|89.4428
8. https://newbedev.com/speech-recognition-python-code-not-working-code-example
9. https://www.py4u.net/discuss/22062

我经历了更多的讨论，一切都是徒劳的。
到目前为止，没有任何解决方案对我有用。请帮忙！！
经过多次不成功的尝试，我至少成功地使用命令

pyaudio

安装了

pipwin install pyaudio

我的Python代码：

import os
import pyttsx3, datetime, pyaudio
import speech_recognition as sr

# Initial Setup for pyttsx3 - speaking abilities
engine = pyttsx3.init("sapi5")
voices = engine.getProperty("voices")
engine.setProperty("voice", voices[1].id)  # 0-male voice , 1-female voice
sr.Microphone.list_microphone_names()

# Initial Setup for speech_recognition - listening abilities
# r.energy_threshold = 10
# print(pyaudio.get_device_count() - 1)


def speak(speakable):
    """speak() takes a string and reads it loud"""
    engine.say(str(speakable))
    engine.runAndWait()


def takeCommand():
    pyaudio.PyAudio()
    r = sr.Recognizer()
    """It takes microphone input from the user and returns string output"""
    with sr.Microphone() as source:
        r.adjust_for_ambient_noise(source, duration=0.9)
        print("Listening...")
        r.pause_threshold = 45
        audio = ""
        try:
            audio = r.listen(source)
            print("Recognizing...")
        except Exception as e:
            print("Listen err: ", e)
        try:
            print("Recognizing...")
            query = r.recognize_google(audio)
            print(f"User said: {query}\n")  # User query will be printed.
        except sr.UnknownValueError as e:
            print("Say that again please...")
            return "None"  # None string will be returned
        except Exception as err:
            print("Check your internet...")
            return "None"
    return query


def wishMe():
    hour = int(datetime.datetime.now().hour)
    if hour >= 0 and hour < 12:
        speak("Good Morning!")

    elif hour >= 12 and hour < 18:
        speak("Good Afternoon!")

    else:
        speak("Good Evening!")
        speak(
            "Hello Sir, I am Friday, your Artificial intelligence assistant. Please tell me how may I help you"
        )


if __name__ == "__main__":
    os.system("CLS")
    while True:
        command = takeCommand().lower()
        print(f"Command: {command}")
        if "wish" in command:
            wishMe()

输出卡在

Listening...

。之后什么也没有发生。

更多信息：

1. 我正在使用

   Windows 10 Home

2. 代码编辑器-

   vs code

3. 我在这个程序中没有使用

   virtual env

   。
4. 我还检查了 Chrome 语音搜索 是否正常工作。
5. 

   python3 -m speech_recognition

   命令的结果

Answer 1

你尝试过

python3 -m speech_recognition

吗？您应该看到类似以下内容：

...
A moment of silence, please...
Set minimum energy threshold to 51.208131879528096
Say something!
Got it! Now to recognize it...
You said hello

如果这不起作用，您的音频系统可能有问题。确保您可以录制音频 (https://onlinehardwaretest.com/microphone-test/) 并考虑重新启动系统。

Answer 2

当我评论这些行时：

def takeCommand():
  .....
 with sr.Microphone() as source:
        #  --> r.adjust_for_ambient_noise(source, duration=0.9) 
        print("Listening...")
        #  -->  r.pause_threshold = 45 
...

对我有用。
