Use the speech_recognition and pydub libraries to handle audio processing and conversion. Install them using pip install SpeechRecognition pydub.
Convert MP3 to WAV format since speech_recognition works best with WAV files. Use pydub to load and convert the MP3: from pydub import AudioSegment sound = AudioSegment.from_mp3("audio.mp3") sound.export("audio.wav", format="wav")
Import speech_recognition and create a recognizer instance:import speech_recognition as sr recognizer = sr.Recognizer()
Use speech_recognition to open the converted WAV file: audio_file = sr.AudioFile("audio.wav") with audio_file as source: audio_data = recognizer.record(source)
Use Google Web Speech API (free) to transcribe the audio to text: text = recognizer.recognize_google (audio_data) print(text)
For long MP3 files, break the audio into chunks to avoid timeouts. Pydub's split_to_mono() method can help with splitting.
