我在Python 2.7中运行以下代码并安装了pyAudio。
import speech_recognition as sr
r = sr.Recognizer()
with sr.Microphone() as source: # use the default microphone as the audio source
audio = r.listen(source) # listen for the first phrase and extract it into audio data
try:
print("You said " + r.recognize(audio)) # recognize speech using Google Speech Recognition
except LookupError: # speech is unintelligible
print("Could not understand audio")
输出指示闪烁。而已。请帮助，因为我是新手。

可能的原因可能是recognizer_instance.energy_threshold属性可能设置为一个太高而无法启动的值。您应该降低此阈值，或致电recognizer_instance.adjust_for_ambient_noise(source, duration = 1)。您可以在Speech Recognition

您尝试更换
print("You said " + r.recognize(audio))
except LookupError:
print("Could not understand audio")
使用
text = r.recognize_google(audio)
print("You said : {}".format(text))
text = r.recognize_google(audio)
except:
print("Sorry could not recognize your voice")
通过运行以下命令确保pyaudio.h已安装
sudo apt-get install portaudio19-dev python-pyaudio python3-pyaudio

检查麦克风的输入音量。在ubuntu中默认设置为0（在我的例子中）。由于您的程序卡在audio = r.listen(source)行，这只是意味着麦克风无法收听任何语音输入。希望这会有所帮助。

除了Tushar的回答，我建议尝试使用更好的外置USB麦克风。 PyAudio可能会出现内置笔记本电脑麦克风的问题。

将Try和Except放在缩进中。
这是我的工作代码： -
`while True:
r=sr.Recognizer()
with sr.Microphone() as source:
print("Say Something")
audio=r.listen(source)
try:
print(r.recognize_google(audio),"\n")
except:
pass`

您可能必须先安装这些东西：
pip install pyaudio pip install --upgrade pyaudio pip install wheel pip install google-api-python-client sudo apt-get install flac pip install monotonic pip install SpeechRecognition 之后，请参考站点（https://realpython.com/python-speech-recognition/） 它会清楚地说明您想要什么。
在这里，我附上我从该站点编辑的代码。由于我是新手，所以它并不完美，但是我已经尝试过了。这是为了检查天气，语音输入与我输入的文字相似，并且还会打印您所说的内容。

我想问题出在持续时间上。如果您为语音识别引擎设置了一定的持续时间，则该问题将得到解决。 尝试以下代码：
import speech_recognition as sr
r = sr.Recognizer()
with sr.Microphone() as source:
speak(sen)
print("listening...")
audio = r.record(source,duration=3)
try:
str=r.recognize_google(audio)
print(str)
except:
print("some error occurred!")

尝试添加
r.adjust_for_ambient_noise(source,duration=1)
其中r是识别器实例，像这样
import speech_recognition as sr
r=sr.Recognizer()
print(sr.Microphone.list_microphone_names())
with sr.Microphone() as source:
r.adjust_for_ambient_noise(source,duration=1)
# r.energy_threshold()
print("say anything : ")
audio= r.listen(source)
try:
text = r.recognize_google(audio)
print(text)

print("sorry, could not recognise")

我的问题是：程序运行没有任何错误，但没有显示任何输出
这是有问题的代码：
import googletrans
import speech_recognition as sr
recognizer = sr.Recognizer()
translator = googletrans.Translator()
try:
with sr.Microphone() as source:
print('Speak Now')
voice= recognizer.listen(source)
text= recognizer.recognize_google(voice)
print(text)
except:
pass
translated = translator.translate(text, dest='es')
print(translated.text)
解决这个问题：
基本上这个问题是由背景噪音或环境噪音引起的
所以只需在您的代码中添加一行，即：
recognizer.adjust_for_ambient_noise(source)#recognizer is on line 4 from above code
######## 改进和解决的问题代码： ########
import googletrans
import speech_recognition as sr
recognizer = sr.Recognizer()
translator = googletrans.Translator()
try:
with sr.Microphone() as source:
print('Speak Now')
recognizer.adjust_for_ambient_noise(source)#(Problem Solved)
voice= recognizer.listen(source)
text= recognizer.recognize_google(voice)
print(text)
except:
pass
translated = translator.translate(text, dest='es')

尝试使用以下方法更改麦克风索引：
with sr.Microphone(device_index = 0) as source:
要了解您的麦克风索引使用情况：
print((sr.Microphone.list_microphone_names()))
如果这不起作用，请使用：
with sr.Microphone(device_index = 0) as source: # use the default microphone as the audio source
r.adjust_for_ambient_noise(source, duration = 1)
audio = r.listen(source)

将语音识别输入为sr
r = sr.Recognizer（）
带有sr.Microphone（）作为来源：
打印（“正在听...”）
音频= r.record（源，持续时间= 3）
尝试：
str = r.recognize_google（音频）
打印（str）
