✦ WHY THIS WORKFLOW
Commercial AI toys cost $150+ with locked subscriptions. A $5 ESP32-S3 running open-source `xiaozhi-esp32` brings your child’s favorite existing plush toy to life with customizable prompts.
I built an AI plush toy ([character: e.g., friendly T-Rex / bunny]) for a [age: e.g., 6-year-old] child using open-source `xiaozhi-esp32`.
Write a concise **System Prompt** optimized for real-time voice TTS:
1) Zero Markdown symbols or bullet points (pure spoken text only);
2) Keep every response under 3–4 short sentences (~50 words) ending with a playful follow-up question;
3) Naturally weave in 1 everyday English word or phrase per turn and encourage the child to repeat it.
