Integrating AI into a doll involves installing electronic components that allow it to sense, process, and respond intelligently. The main hardware includes a compact computer like a Raspberry Pi, along with a microphone, speaker, and optional features like a camera or touch sensors. These parts let the doll hear, speak, and react to interactions. If you want movement, servo motors can be added to control the head, eyes, or limbs.
On the software side, the AI system typically includes speech recognition to understand spoken words, a language model to generate replies, and a text-to-speech engine to talk back. The AI can be trained or programmed to remember conversations, show simulated emotions, or even respond differently based on tone or keywords. Together, the hardware and software give the doll a lifelike presence, making it feel more like an interactive companion than a toy.
