Python SpeechRecognition Module
The SpeechRecognition library allows you to convert audio into text. It supports several engines and APIs, including Google Speech Recognition, Sphinx, and OpenAI Whisper.
Installation
pip install SpeechRecognitionTo use the microphone input, you also need PyAudio.
# Windows
pip install pyaudio
# Linux (requires portaudio dev headers)
# sudo apt-get install python3-pyaudioRecognizing from Audio File
import speech_recognition as sr
r = sr.Recognizer()
with sr.AudioFile('audio.wav') as source:
audio_data = r.record(source)
text = r.recognize_google(audio_data)
print(text)Recognizing from Microphone
import speech_recognition as sr
r = sr.Recognizer()
with sr.Microphone() as source:
print("Say something!")
# Adjust for ambient noise
r.adjust_for_ambient_noise(source)
audio = r.listen(source)
try:
print("You said: " + r.recognize_google(audio))
except sr.UnknownValueError:
print("Google Speech Recognition could not understand audio")
except sr.RequestError as e:
print(f"Could not request results from Google Speech Recognition service; {e}")Supported Engines
