Getting error while transcribing mp3 file into text file
8 août 2021, par Parul VermaI used the below code to transcribe the mp3 file into text.


import speech_recognition as sr
from pydub import AudioSegment

# convert mp3 file to wav 
src=(r"C:\Users\user.name\Desktop\python\DATA\Audio files\Audio1.mp3")
sound = AudioSegment.from_mp3(src)
sound.export(r"C:\Users\user.name\Desktop\python\DATA\Audio files\Audio1.wav"), format="wav")

file_audio = sr.AudioFile(r"C:\Users\user.name\Desktop\python\DATA\Audio files\Audio1.wav")

# use the audio file as the audio source 
r = sr.Recognizer()
with file_audio as source:
 audio_text = r.record(source)

print(type(audio_text))
print(r.recognize_google(audio_text))


But I got the following error-


FileNotFoundError Traceback (most recent call last)

avformat/utils : Discard huge timestamps which would cause overflows if used in basic...
25 septembre 2016, par Michael Niedermayeravformat/utils : Discard huge timestamps which would cause overflows if used in basic computations
Allowing larger timestamps makes it impossible to calculate basic things like the
difference of 2 timestamps or their sum without checking each individual computation for
overflow.
This should avoid a significant number of overflow checksFixes Ticket5136
