this is my repository - GitHub - aditya230302/Lexi
main.py file is the one I am deploying.
The app works fine on local host but on Cloud its showing:

when using audio features:

OSError: This app has encountered an error. The original error message is redacted to prevent data leaks. Full error details have been recorded in the logs (if you’re on Streamlit Cloud, click on ‘Manage app’ in the lower right of your app).

Traceback:

and when using OCR:

    img = cv2.resize(img,(int(model_height*ratio),model_height),interpolation=Image.Resampling.LANCZOS)

can someone help me resolve this issue

This aproach will not work as soon as the application runs on any hosted environment, because there is neither a microphone nor a camera, at least these code lines below will not work, but there are probably more issues.

with sr.Microphone() as source:  # there is no microphone on the server
...
cap = cv2.VideoCapture(0)  # there is also no camera

This is a common misconception about how streamlit works. Everything has to go through the browser or browser APIs. You have to use streamlit components that can access audio/video devices.
