使用 Python 和 PyAudio 的语音转文本无法在操作系统上运行

【中文标题】使用 Python 和 PyAudio 的语音转文本无法在操作系统上运行

【英文标题】：Speech to Text using Python & PyAudio not working on OS

【发布时间】：2020-02-10 10:51:56

【问题描述】：

我正在尝试在 Python 3.7（OS X/内置麦克风）上使用语音识别库

这是我目前使用的代码：

import speech_recognition as sr

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

print("Google Speech Recognition thinks you said " + r.recognize_google(audio))

但是，当我运行程序时，没有输出，也没有错误消息。但是当我点击“停止”按钮时，会出现此错误消息

Traceback（最近一次调用最后一次）： 文件“/Users/diandraelmira/PycharmProjects/untitled/venv/APP.py”，第 6 行，在 音频 = r.listen（来源） 文件“/Users/diandraelmira/PycharmProjects/untitled/venv/lib/python3.7/site-packages/speech_recognition/init.py”，第 620 行，听 缓冲区 = source.stream.read(source.CHUNK) 文件“/Users/diandraelmira/PycharmProjects/untitled/venv/lib/python3.7/site-packages/speech_recognition/init.py”，第 161 行，读取 return self.pyaudio_stream.read(size, exception_on_overflow=False) 文件“/Users/diandraelmira/PycharmProjects/untitled/venv/lib/python3.7/site-packages/pyaudio.py”，第 608 行，已读 返回 pa.read_stream(self._stream, num_frames, exception_on_overflow) 键盘中断

我该如何解决这个问题？

【参考方案1】：

您好，请您尝试一下，然后查找错误

try:
    print("Sphinx thinks you said " + r.recognize_sphinx(audio))
except sr.UnknownValueError:
    print("Sphinx could not understand audio")
except sr.RequestError as e:
    print("Sphinx error; 0".format(e))

【参考方案2】：

我认为您的代码需要稍作改动，它是：

import speech_recognition as sr

rObject = sr.Recognizer() 
audio = '' 
with sr.Microphone() as source: 
    print("Speak...")   
    audio = rObject.listen(source, phrase_time_limit = 0) 
    print("Stop.")
    try: 
        text = rObject.recognize_google(audio, language ='en-US') 
        print("You : "+ text)  
    except: 
        speak("Could not understand your audio...PLease try again !") 

试试这个！希望错误能得到解决。

【参考方案3】：

使用以下代码：

#import library

import speech_recognition as sr

# Initialize recognizer class (for recognizing the speech)

r = sr.Recognizer()

# Reading Microphone as source
# listening the speech and store in audio_text variable

with sr.Microphone() as source:
    print("Talk")
    audio_text = r.listen(source)
    print("Time over, thanks")
# recoginize_() method will throw a request error if the API is unreachable, hence using exception handling
    
    try:
        # using google speech recognition
        print("Text: "+r.recognize_google(audio_text))
    except:
         print("Sorry, I did not get that")

希望它有效。
