Python: Portaudio Errno -9986 内部 PortAudio 错误

Question

我正在尝试运行一个简单的 python 语音识别程序。代码如下：

import speech_recognition as sr
import pyttsx3 


r = sr.Recognizer()  

engine = pyttsx3.init("nsss",True)

engine.say("hello")
engine.runAndWait()


while True:
    try:
        print("starting process")
        with sr.Microphone() as source2:    
            r.adjust_for_ambient_noise(source2, duration=0.2)  
            print("completed adjustment")
            audio2 = r.listen(source2) 
            MyText = r.recognize_google(audio2) 
            MyText = MyText.lower() 
            print("Did you say "+MyText) 
            SpeakText(MyText) 
    
    except sr.RequestError as e:
        print("Could not request results; {0}".format(e))
    except sr.UnknownValueError:
        print("an unknown error occured")

当运行时，语音测试成功说出“你好”，但随后抛出

||PaMacCore (AUHAL)|| Failed to open AUHAL component.||PaMacCore (AUHAL)|| Error on line 1263: err='-50', msg=Unknown Error
Traceback (most recent call last):

OSError: [Errno -9986] Internal PortAudio error

我已经尝试用 brew 卸载并重新安装 portaudio。

我运行在 musescore 中遇到了与 portaudio 类似的问题，运行使用 sudo 解决了这个问题。

Answer 1

安装 Mojave 后，您能否确认您的麦克风工作正常并且没有受到音频问题的影响，参考 here。

您的代码看起来不错。看起来错误是由您的 microphone 系统中的某些故障引起的。确保您已正确遵循包索引页面中的 instructions。值得注意的是，

PyAudio (for microphone users) PyAudio is required if and only if you want to use microphone input (Microphone). PyAudio version 0.2.11+ is required, as earlier versions have known memory management bugs when recording from microphones in certain situations.
