speech recognition python code not working

Question

I am running the following code in Python 2.7 with pyAudio installed.

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


        

Answer 1

try this code:

r = sr.Recognizer()

with sr.Microphone() as source:
        r.adjust_for_ambient_noise(source=source)
        audio = r.listen(source,timeout=3)
        

    
    data = ''
    try :
        data = r.recognize_google(audio)
        print(data)

    except sr.UnknownValueError:
        print(" Error")
        
    except sr.RequestError as e:
        print("Request Error")

or add timeout and r.adjust_for_ambient_noise(source=source) to your code as above.please can anyone help me with this

Answer 2

check the input volume of your microphone. It is by default set to 0 in ubuntu (in my case). Since your program got stuck on the line audio = r.listen(source), which simply means that the microphone is not able to listen to any voice input. Hope this helps.

Answer 3

The possible reason could be that the recognizer_instance.energy_threshold property is probably set to a value that is too high to start off with. You should decrease this threshold, or call recognizer_instance.adjust_for_ambient_noise(source, duration = 1). You can learn more about it at Speech Recognition

Answer 4

just try;

pip install sounddevice

it works.

Answer 5

In addition to Tushar's answer, I suggest trying a nicer external USB microphone. PyAudio can have issues with a simple built-in laptop microphone.

Answer 6

Please set minimum threshold.

After running commend python -m speech_recognition. Set minimum energy threshold which it display.

Setting procedure: press Ctrl then click mouse Recognizer(). Now set energy threshold.
