Offline speech recognition, high-precision response Built in high-performance neural network processor, supports convolutional neural operations and deep learning denoising, and can complete speech instruction recognition without the need for a network. In quiet environments, the recognition distance can reach 5 meters, and in noisy environments, it can still stably recognize voice commands within 1 meter, with a recognition accuracy of up to 99%. Integrated design, simplified development The module integrates high fidelity speakers and noise cancelling microphones, and has a built-in 2MB storage space. It comes with over 100 sets of commonly used voice word libraries, ready to use out of the box. No need for complex circuit design, effectively reducing hardware deployment costs. Dual communication interfaces, flexible adaptation The onboard GH1.25-6Pin interface supports both UART and IIC communication, and users can freely choose the communication method according to project requirements. Reserve PH2.0-4Pin pad positions for secondary development. Color: Black Material: PCB+Metal Package Contents: 1 * AI voice module Only the above package content, other products are not included.
