Build a portable AI assistant powered by CuteAssistant GPT. Voice input via built-in mic, responses on the AMOLED display.

Overview

Create a portable AI voice assistant using the Kode Dot's built-in microphone, speaker, and WiFi connectivity. The CuteAssistant GPT app handles speech-to-text and GPT inference via cloud API, displaying cute animated responses on the AMOLED screen.

What you'll build

  • Wake word detection ("Hey Kode")
  • Voice-to-text transcription
  • GPT-powered responses
  • Text-to-speech playback
  • Animated character on screen

How It Works

Architecture

Mic → Wake word → Record audio → WiFi → Cloud STT → GPT → TTS → Speaker

The device listens for the wake word locally using a tiny neural network. Once triggered, it records 5 seconds of audio, sends it to a cloud Speech-to-Text API, forwards the transcript to GPT, and plays back the synthesized response.

Tips

  • Use short prompts for faster responses
  • The built-in speaker works best in quiet environments
  • WiFi latency is typically 200-500ms per round-trip
