Extract Text From Videos using Python Project with source code

Speech recognition is an interesting task that allows you to recognize the text behind the audio. With the use of voice recognition, we can also extract text from a video. In this article, I will walk you through how to extract text from videos using Python.

Extract Text From Videos using Python
In this section, I will take you through how to extract text from a video using Python. The first step is to download a video. After downloading the videos you need to install two Python libraries:

• Speech Recognition: pip install Speech Recognition
• moviepy: pip install moviepy
• After installing the above two Python libraries you can start with coding. Here is the complete Python program to convert a video into the text:

import speech_recognition as sr 
import moviepy.editor as mp
from moviepy.video.io.ffmpeg_tools import ffmpeg_extract_subclip

num_seconds_video= 52*60
print("The video is {} seconds".format(num_seconds_video))
l=list(range(0,num_seconds_video+1,60))

diz={}
for i in range(len(l)-1):
    ffmpeg_extract_subclip("videorl.mp4", l[i]-2*(l[i]!=0), l[i+1], targetname="chunks/cut{}.mp4".format(i+1))
    clip = mp.VideoFileClip(r"chunks/cut{}.mp4".format(i+1)) 
    clip.audio.write_audiofile(r"converted/converted{}.wav".format(i+1))
    r = sr.Recognizer()
    audio = sr.AudioFile("converted/converted{}.wav".format(i+1))
    with audio as source:
      r.adjust_for_ambient_noise(source)  
      audio_file = r.record(source)
    result = r.recognize_google(audio_file)
    diz['chunk{}'.format(i+1)]=result

After executing the above Python code you need to create a text document to store all the text that has been extracted from the video:

l_chunks=[diz['chunk{}'.format(i+1)] for i in range(len(diz))]
text='\n'.join(l_chunks)

with open('recognized.txt',mode ='w') as file: 
   file.write("Recognized Speech:") 
   file.write("\n") 
   file.write(text) 
   print("Finally ready!")

NOTE – In order to run the project of Python, you have to download Python IDLE or Pycharam. In the video I have explained how to download and install it.
