Python Tutorial – Speech Recognition (Personal Assistant)

In this tutorial, we will learn how to build a simple personal assistant using speech recognition in Python.

1. Installing the Required Libraries

First, you will need to install the necessary libraries. You can install them using pip:

pip install pyttsx3
pip install SpeechRecognition
pip install pyaudio

2. Setting up the Speech Recognition

Now, let’s create a Python script to set up the speech recognition and create our personal assistant:

import speech_recognition as sr
import pyttsx3

# Initialize the speech recognizer
recognizer = sr.Recognizer()

# Initialize the text-to-speech engine
engine = pyttsx3.init()

# Function to speak the given text
def speak(text):
    engine.say(text)
    engine.runAndWait()

# Function to listen to the user
def listen():
    with sr.Microphone() as source:
        recognizer.adjust_for_ambient_noise(source)
        audio = recognizer.listen(source)

        try:
            text = recognizer.recognize_google(audio)
            return text
        except sr.UnknownValueError:
            return "Sorry, I did not understand that."
        except sr.RequstError:
            return "Sorry, my speech service is down."

3. Using the Personal Assistant

Now that we have set up our personal assistant, let’s create a simple interaction using it:

speak("Hello! How can I help you?")
text = listen()
speak("You said: " + text)

That’s it! You now have a simple personal assistant that can listen to your voice commands and respond accordingly.
