为什么我的 Python 语音识别码不起作用

Question

I'm trying to make a simple speech recognition program, and this is the code I have currently.

import speech_recognition as sr
from speech_recognition import Microphone
from speech_recognition import Recognizer

mic = sr.Microphone()
r = sr.Recognizer()
sr.Microphone.list_working_microphones()

for device_index in Microphone.list_working_microphones():
    Microphone(device_index=4)
    break
else:
    print("No working microphones found!")

with mic as source:
    print("say something:")
    audio = r.listen(source)
    request = r.recognize_google(audio)
    print(request)

It used to work, but now it doesn't. What it does do is print "say something:", but it doesn't listen for my voice. I do have pyaudio installed, so that isn't the issue.

My microphone has a little red LED that flashes when in use, so based on that I assume that python is using the microphone.

I've reinstalled all of the packages, and also tried using PocketSphinx, but it doesn't solve the issue.

Why is this? It's a bit infuriating and I don't understand why this could be happening.

Any help appreciated.

Answer 1

Look at this example code more closely .

You don't need to pull out a variable for mic .

Also, that function, as documented says microphones currently hearing sound , which probably isn't want you want while working in a quiet environment.

import speech_recognition as sr
import pyaudio
m = None
for device_index in sr.Microphone.list_working_microphones():
    m = sr.Microphone(device_index=device_index)
    break
else:
    raise Error("No working microphones found!")

if m is not None:
    print("Mic ready")

    # Now you are ready to recognize
    r = sr.Recognizer()

If you want the code from the docs, exactly

import Microphone, Recognizer from speech_recognition

Then use Microphone rather than sr.Microphone
