Question

我希望得到一个简单的语音识别功能。我一直在关注speech_recognition，当我执行代码时发生以下错误

import speech_recognition as sr
r = sr.Recognizer()
with sr.Microphone() as source:                
    audio = r.listen(source)                  

try:
    print("You said " + r.recognize(audio))    
except LookupError:                            




print("You said " + r.recognize(audio))    # recognize speech using Google       Speech Recognition
AttributeError: 'Recognizer' object has no attribute 'recognize'

    print("Could not understand audio")

这是从他们网页上的示例中复制的

Answer 1

我遇到了同样的问题。问题是我没有设置最低阈值水平。所以我添加了这段代码。

Project editor

现在它的工作完美!!!

Answer 2

我得到了它的工作。

import speech_recognition as sr

# obtain audio from the microphone
r = sr.Recognizer()
with sr.Microphone() as source:
    print("Say something!")
    audio = r.listen(source)

print(r.recognize_google(audio))

Answer 3

您使用的是什么版本的SpeechRecognition库？

您可以查看：

import speech_recognition as sr
print sr.__version__

如果您使用的是最新版本（SpeechRecognition 3.1.3），则应使用recognize_google()方法代替recognize()，以使用Google API。

至于最新文档，您可以查找here，还可以查看一些有用的examples。

Answer 4

我已经采用了实际执行但未能打印出我所说的代码的代码

注意：此示例需要PyAudio，因为它使用Microphone类

import speech_recognition as sr
import pyaudio

# obtain audio from the microphone
r = sr.Recognizer()
with sr.Microphone() as source:
    print("Say something!")
    audio = r.listen(source)

# recognize speech using Google Speech Recognition
try:
    # for testing purposes, we're just using the default API key
    # to use another API key, use `r.recognize_google(audio, key="GOOGLE_SPEECH_RECOGNITION_API_KEY")`
    # instead of `r.recognize_google(audio)`
    print("Google Speech Recognition thinks you said " + r.recognize_google(audio))
except sr.UnknownValueError:
    print("Google Speech Recognition could not understand audio")
except sr.RequestError as e:
    print("Could not request results from Google Speech Recognition service; {0}".format(e))

# recognize speech using Wit.ai
WIT_AI_KEY = "INSERT WIT.AI API KEY HERE" # Wit.ai keys are 32-character uppercase alphanumeric strings
try:
    print("Wit.ai thinks you said " + r.recognize_wit(audio, key=WIT_AI_KEY))
except sr.UnknownValueError:
    print("Wit.ai could not understand audio")
except sr.RequestError as e:
    print("Could not request results from Wit.ai service; {0}".format(e))

# recognize speech using IBM Speech to Text
IBM_USERNAME = "INSERT IBM SPEECH TO TEXT USERNAME HERE" # IBM Speech to Text usernames are strings of the form XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX
IBM_PASSWORD = "INSERT IBM SPEECH TO TEXT PASSWORD HERE" # IBM Speech to Text passwords are mixed-case alphanumeric strings
try:
    print("IBM Speech to Text thinks you said " + r.recognize_ibm(audio, username=IBM_USERNAME, password=IBM_PASSWORD))
except sr.UnknownValueError:
    print("IBM Speech to Text could not understand audio")
except sr.RequestError as e:
    print("Could not request results from IBM Speech to Text service; {0}".format(e))

# recognize speech using AT&T Speech to Text
ATT_APP_KEY = "INSERT AT&T SPEECH TO TEXT APP KEY HERE" # AT&T Speech to Text app keys are 32-character lowercase alphanumeric strings
ATT_APP_SECRET = "INSERT AT&T SPEECH TO TEXT APP SECRET HERE" # AT&T Speech to Text app secrets are 32-character lowercase alphanumeric strings
try:
    print("AT&T Speech to Text thinks you said " + r.recognize_att(audio, app_key=ATT_APP_KEY, app_secret=ATT_APP_SECRET))
except sr.UnknownValueError:
    print("AT&T Speech to Text could not understand audio")
except sr.RequestError as e:
    print("Could not request results from AT&T Speech to Text service; {0}".format(e))

我得到以下读出

说些什么！谷歌语音识别认为你打招呼无法请求Wit.ai服务的结果;识别请求失败：错误请求无法从IBM Speech to Text服务请求结果;识别请求失败：未经授权无法请求AT＆amp; T Speech to Text服务的结果;凭证请求失败：未经授权

Python 3.4的语音识别易于使用？
