you are on the right track. The function doesn’t return anything which is why you are probably seeing that error.

try this modified code. added a return statement instead of print:
If it doesn’t work, try debugging in your IDE and let me know which line no is it erroring on.

import speech_recognition as sr
import time
from pydub import AudioSegment
from pathlib import Path

def convert_audio_to_text(src):

    dst = Path(src).with_suffix('.wav')

    # convert wav to mp3                                                            
    audSeg = AudioSegment.from_mp3(src)
    audSeg.export(dst, format="wav")

    r = sr.Recognizer()
    with sr.AudioFile(dst) as source:
        audio = r.listen(source)

        try:
            print("Reading audio file. Please, wait a moment...")
            text = r.recognize_google(audio, language='en-US')
            time.sleep(1.5)
            # print(text)
            return text
        except:
            return "I am sorry! I can not understand!"




x = convert_audio_to_text('C:\\Users\\TTssRpaConba\\Desktop\\audio.mp3')
print(x)
