Generative AI SMART SPEAKER

Smart speakers such as Alexa, Google Home, and Apple Home have transformed how people interact with technology, enabling voice-based control of smart devices, instant access to information, and efficient task management.

However, most still rely on predefined responses and offer limited intelligence compared to modern generative AI systems.

To overcome these limitations, a Generative AI smart speaker has been developed using advanced large language models (LLMs). Unlike conventional smart speakers, it can generate stories, poems, jokes, emails, and other content on demand while providing more intelligent assistance for everyday tasks. The system supports multiple AI platforms, enabling seamless switching between providers such as OpenAI, DeepSeek, Grok, and others.

To further extend its capabilities, the smart speaker incorporates a camera. This allows it to read and transcribe books, scan documents, identify objects, describe surroundings, and provide contextual information about items or locations within view. It can also function as a real-time language interpreter and an assistive device for visually impaired users. The prototype is shown in Fig. 1.

The core of this design is a Raspberry Pi board (such as the Raspberry Pi Zero W, Raspberry Pi 4, Raspberry Pi 5, or a similar model) equipped with Bluetooth Low Energy (BLE) and WiFi connectivity. For audio input and output, a Raspberry Pi-compatible voice HAT with microphone and speaker support is required. In the prototype, a Google Voice Bonnet is used for audio processing. Video capture is handled by the official Raspberry Pi camera, which connects directly to the Raspberry Pi through its CSI camera interface.

Along with these key modules, several supporting components are required to complete the system. The components needed to build the system are listed in the Bill of Materials table.
