SpeechRecognition 不工作（未检测到麦克风）

Question

我想用语音识别做一个小程序。

这是我的代码（经典代码）：

import speech_recognition as sr
r = sr.Recognizer()

with sr.Microphone() as source:
    print("SAY SOMETHING")
    audio = r.listen(source,timeout=3, phrase_time_limit=3)
    print("TIME OVER")
try:
    print("TEXTE : "+r.recognize_google(audio, language="fr-FR"))
except Exception:
    print("ERROR")

但是当我尝试启动程序时出现此错误：

ALSA lib pcm_dsnoop.c:638:(snd_pcm_dsnoop_open) unable to open slave
ALSA lib pcm.c:2565:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear

当我这样做时 arecord -l 我有这个 :

**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC298 Analog [ALC298 Analog]
Subdevices: 0/1
Subdevice #0: subdevice #0

Ps : 麦克风适用于任何软件，如 Skype 或 Google

Answer 1

尝试：更改您的默认麦克风设备。

Answer 2

我的一个项目中有一个有效的代码片段试试这个它可能会起作用：

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 ='fr-FR') 
        print("You : "+ text)  
    except: 
        speak("Could not understand your audio...PLease try again !")

运行这个片段，我认为有一些名为 PyAudio 的包的问题...没有正确安装，如果没有 pyaudio 它将无法工作（特别是在 python 2.7 中没有 pyaudio 将无法工作。

Answer 3

尝试将 PyAudio 安装到您的代码中以消除错误。甚至尝试连接到网络或让您的麦克风正常工作。

Answer 4

如何在异常块中添加一个Speech_regognition超时错误

with sr.Microphone() as source:
    print("SAY SOMETHING")
    audio = r.listen(source,timeout=3, phrase_time_limit=3)
    print("TIME OVER")
try:
    print("TEXTE : "+r.recognize_google(audio, language="fr-FR"))
except sr.WaitTimeoutError:
    print("ERROR")

Answer 5

def takecommand():
r = sr.Recognizer()
with sr.Microphone() as source:
    r.adjust_for_ambient_noise(source, 1)
    print("Listening....")
    speak("listening")
    audio = r.listen(source)


    try:
        print("Recognizing...")
        query = r.recognize_google(audio, language='en-in')
        print(f"You said: {query}\n ")

    except sr.UnknownValueError:
        speak("Could not hear that, Try saying again")

    except sr.RequestError:
        speak("Make Sure that you have a good Internet connection")
    return query

您必须通过 pip install pyttsx3 import pyttsx3 并且通过 pip install SpeechRecognition import speech_recognition as sr 然后您的代码才能工作。
