How To Convert Mp3 To Text Using Python – Guide #2023

Python is a programming language that lets you work more quickly and integrate your systems more effectively. You can learn to use Python and see almost immediate gains in productivity and lower maintenance costs.

Python runs on Windows, Linux/Unix, Mac OS X, OS/2, Amiga, Palm Handhelds, and Nokia mobile phones. Python has also been ported to the Java and .NET virtual machines. Python is distributed under an open source license that makes it free to use, even for commercial products.

How To Convert Mp3 To Text Using Python?

This is a guide to converting Mp3 files into text using Python. You will need the following tools: Python 3, FFmpeg, and Pydub.

First, you will need to download Python 3 from the Python website. Next, install FFmpeg. You can find instructions on how to do this here. Finally, install Pydub by running pip install pydub in your terminal.

Once you have all of the dependencies installed, open up a Python file and import the following packages:

import speech_recognition as sr

from pydub import AudioSegment

import os

import sys

The first two lines are imports for the speech recognition and pydub packages. The third line imports the os module, which will be used to interface with the filesystem. The fourth line imports the sys module, which will be used to exit the program if an error occurs.

Next, define a function that takes an MP3 file as input and returns the text as output:

def mp3_to_text(filename):

r = sr.Recognizer()

with sr.AudioFile(filename) as source:

audio = r.record(source)

try:

return r.recognize_google(audio)

except sr.UnknownValueError:

print("Google Speech Recognition could not understand audio")

except sr.RequestError as e:

print("Could not request results from Google Speech Recognition service; {0}".format(e))

sys.exit()

This function takes a filename as input and initializes the speech recognizer. Next, it records the audio from the file and tries to recognize it using the Google Speech Recognition API. If it is able to successfully recognize the audio, it will return the text. Otherwise, it will print an error message and exit the program.

Now that we have our mp3_to_text function defined, we can use it to convert MP3 files to text:

filename = "audio.mp3"

text = mp3_to_text(filename)

print(text)

This will convert the MP3 file audio.mp3 to text and print it to the console. You can also save the text to a file by writing it to a file instead of printing it:

filename = "audio.mp3"

text = mp3_to_text(filename)

with open("output.txt", "w") as f:

f.write(text)

This will write the text to a file called output.txt in the same directory as your Python script.

Example

import speech_recognition as sr
from pydub import AudioSegment

# convert mp3 file to wav  
src=(r"C:\Users\Andrew\Podcast.mp3")
sound = AudioSegment.from_mp3(src)
sound.export("C:\Users\Andrew\podcast.wav", format="wav")

file_audio = sr.AudioFile(r"C:\Users\Andrew\Podcast.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))

Python is a powerful programming language that can be used for many different tasks, from automating everyday tasks to building complex applications. In this guide, we’ve shown you how to use Python to convert MP3 files to text. With just a few lines of code, you can easily add this functionality to your own Python scripts.
