Today, it all comes together. In this lesson, you'll design the architecture of your very own AI assistant—one that sees, hears, speaks, and acts. No full coding yet—this is about planning your system like a real engineer.
🧠 What You’ll Learn Today:
- What makes AI assistants like Siri, Alexa, and Google Assistant tick
- How to break your assistant into modular components
- How to design the core logic using pseudocode and system diagrams
- How to plan for voice interaction, camera detection, and smart actions
🤖 What Makes a Great Assistant?
Good assistants:
- Can listen and understand voice commands
- Can see and detect people or objects
- Can respond intelligently and take real-world actions
Your version will:
✅ Use speech recognition to listen
✅ Use object detection to see
✅ Use a local LLM to understand
✅ Use text-to-speech to respond
✅ Trigger lights, alerts, or custom actions
💡 Brainstorm Features Like:
- “Greet me when I walk in”
- “Tell me a joke when I ask”
- “Turn off the light when no one is in the room”
- “Send an alert if someone enters after 10PM”
- “Play a sound when I say a secret command”
🔧 System Architecture (Modular Design):
- Vision Module – Detects people and objects
- Audio Input Module – Captures voice and transcribes to text
- Language Module – Processes commands with a local LLM
- Output Module – Uses TTS and triggers hardware responses
🧪 Pseudocode Flow Example:
while True:
frame = capture_camera()
if detect_person_in_zone(frame):
speak("Hello! How can I help you today?")
audio = listen_for_speech()
text = transcribe(audio)
response = generate_response(text)
speak(response)
💭 Make it your own! Add conditions, timers, or extra logic.
📋 Design Checklist:
- Decide what your assistant will say and do
- List the features you want to include
- Choose a wake word or trigger condition
- Sketch a flowchart or write pseudocode to map the logic
- Organize your program into modular Python files or functions
📝 Homework:
- Plan your assistant’s behavior on paper or in a doc
- Write out pseudocode or a block diagram of the system flow
- Share your assistant design in #assistant-framework for peer feedback
