How to Create an AI Voice Assistant on Android Using Python (No PC Needed!)

🎯 What You'll Learn

• How to turn voice into text in Python
• How to make Python speak using text-to-speech
• How to make a personal AI assistant
• Run everything on Android with PyDroid 3

📱 Why This Is Exciting

You can talk to your phone, and it will reply using AI-generated voice! No PC, no internet required. Just Python, your phone, and your voice. Great for students, coders, and AI enthusiasts.

🔧 Required Packages in PyDroid 3

Open PyDroid 3 and install these from the PIP menu:

• speechrecognition
• pyttsx3
• pyaudio

🧠 Python Code for the AI Assistant

Copy
import speech_recognition as sr
import pyttsx3Initialize engine

engine = pyttsx3.init()

def speak(text): engine.say(text) engine.runAndWait()

def listen(): r = sr.Recognizer() with sr.Microphone() as source: print("Listening...") audio = r.listen(source) try: command = r.recognize_google(audio) print("You said:", command) return command except: speak("Sorry, I didn't catch that.") return ""

speak("Hi! I am your assistant. How can I help you?") while True: query = listen().lower() if "stop" in query: speak("Goodbye!") break elif "your name" in query: speak("I am Codeverix Assistant.") elif "hello" in query: speak("Hello there!") else: speak("You said " + query) 

💾 How to Run the Code

1. Open PyDroid 3
2. Tap editor and paste the code
3. Save as voice_bot.py
4. Make sure your microphone permission is enabled
5. Run and start talking!

🧪 How It Works

• speech_recognition: listens and converts voice to text
• pyttsx3: converts text back to spoken voice
• while loop: keeps assistant running until "stop"

💡 Upgrade Ideas

• Add internet search with wikipedia module
• Control phone features like flashlight or alarms (advanced)
• Personalize responses with name and voice
• Add ChatGPT integration for smart replies
