Error in r.listen(source) while using the speech recognition module

I am trying to run a basic code for speech recognition. But I am getting an error in the following line:

audio = r.listen(source)

The small piece of code that I am trying is:

import speech_recognition as s_r
print(s_r.__version__) # just to print the version not required
r = s_r.Recognizer()
my_mic = s_r.Microphone() #my device index is 1, you have to put your device index
with my_mic as source:
    print("Say now!!!!")
    audio = r.listen(source) #take voice input from the microphone
print(r.recognize_google(audio)) #to print voice into text

I have developed multiple projects using this code but this time I am getting the following error:

3.10.0
Say now!!!!
Traceback (most recent call last):
  File "D:\professional\JARVIS\assistant\test.py", line 7, in <module>
    audio = r.listen(source) #take voice input from the microphone
  File "C:\Users\theas\AppData\Roaming\Python\Python38\site-packages\speech_recognition\__init__.py", line 465, in listen
    assert source.stream is not None, "Audio source must be entered before listening, see documentation for ``AudioSource``; are you using ``source`` outside of a ``with`` statement?"
AssertionError: Audio source must be entered before listening, see documentation for ``AudioSource``; are you using ``source`` outside of a ``with`` statement?

During handling of the above exception, another exception occurred:

I am using this code on a new system with Windows 11. I have installed a fresh Python with default settings with version 3.11.4. The following library versions have been installed for speech recognition:

SpeechRecognition: 3.10.0
Pyaudio: 0.2.13

The same code is working in my other system. Please help me find this silly mistake I made during the setup.

UPDATE: When I try to print the objects of my_mic. I get the following output:

['CHUNK', 'MicrophoneStream', 'SAMPLE_RATE', 'SAMPLE_WIDTH', '__class__', '__delattr__', '__dict__', '__dir__', '__doc__', '__enter__', '__eq__', '__exit__', '__format__', '__ge__', '__getattribute__', '__getstate__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', 'audio', 'device_index', 'format', 'get_pyaudio', 'list_microphone_names', 'list_working_microphones', 'pyaudio_module', 'stream']

When I try to get a list of all the microphones present, I get a large list. But when I try to get the list of working microphones, that is empty.

Solution

  • Finally, I found the root cause of the issue. As I mentioned, I am using Windows 11. And it does not allow the Microphone access to every application. We need to provide permission for it explicitly.

    The way to provide the permission is:

    Settings > Privacy and Security > Microphone

    Then enable the access by allowing other applications to use the Microphone.

    Permission Setting

    This has fixed my issue and the code is working fine. Thank you, everyone, for your valuable suggestions.
