How do I Transcribe Audio Recordings to Text in Python?


If you have ever needed to transcribe an audio recording to text, you know how time-consuming and tedious the process can be. Thankfully, there is a way to automate the process using the Python programming language. In this blog post, we will show you how to transcribe audio recordings to text using Python.

To transcribe audio recordings to text, we will need to use the SpeechRecognition and pydub libraries.

The SpeechRecognition library provides us with a way to recognize speech in audio recordings, while the pydub library allows us to convert audio files into formats that can be recognized by the SpeechRecognition library.

We will start by installing both libraries. We can do this using the pip package manager:

pip install speech_recognition pip install pydub

Next, we will need to create a Python script and import the libraries that we installed:

import speech_recognition import os from pydub import AudioSegment
Code language: JavaScript (javascript)

Now that we have imported the necessary libraries, we can begin transcribing our audio recording. We will start by creating a function that takes an audio file as an input and outputs a text transcript:

def transcribe_audio(audio_file): # initialize the recognizer r = speech_recognition.Recognizer() # convert audio file into format that can be recognized by recognizer sound = pydub.AudioSegment.from_mp3(audio_file) # prepare recognizer with source audio file with speech_recognition.AudioFile(sound) as source: # recognize speech in the recording sound = r.record(source) # try converting speech to text try: # print transcription results return(r.recognize_google(sound)) except sr.UnknownValueError: print("Could not understand audio") return "Could not understand audio" except sr.RequestError as e: print("Could not request results; {0}".format(e)) return "Could not request results; {0}".format(e) else: print("Could not recognize speech") return "Could not recognize speech"
Code language: Python (python)

Now, all we have to do is call the transcribe_audio() function on our desired audio file:

output = transcribe_audio('audio_file.mp3') print(output)
Code language: PHP (php)

And that’s it! You have now successfully transcribed an audio recording to text using Python.

Conclusion:

As you can see, transcribing audio recordings to text is a relatively simple process when you use Python. This method can save you hours of time and energy that would otherwise be spent manually transcribing audio recordings. We hope you found this blog post helpful and that you will give this method a try the next time you need to transcribe an audio recording!
