无法通过任何方法通过Speech_Recognition Python获取音频？

2022-04-02 00:00:00 python speech-recognition pyaudio

问题描述

我正在试着让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不适合我。
  4. speech recognition python code not working
  5. Errors on PyAudio on Visual studio code Python
  6. I can't install pyaudio on Windows? How to solve "error: Microsoft Visual C++ 14.0 is required."?
  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

我又讨论了很多次，都是徒劳的。
到目前为止，没有一种解决方案对我有效。请帮帮我！！
在多次尝试失败后，我至少成功地使用命令pipwin install pyaudio

安装了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}
")  # 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()

输出在Listening...处停滞。之后不会发生任何事情。

更多信息：

  1. 我正在使用Windows 10 Home
  2. 代码编辑器-vs code
  3. 我不会在此程序中使用virtual env。
  4. 我还检查了Chrome Voice Search工作正常，没有任何问题。
  5. python3 -m speech_recognition命令结果

解决方案

您是否尝试过python3 -m speech_recognition？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

如果不起作用，则可能是您的音频系统有问题。请确保您可以录制音频(https://onlinehardwaretest.com/microphone-test/)，并考虑重新启动系统。
