1. The voice interaction module integrates voice recognition and voice broadcasting. It not only integrates a microphone and a speaker, but also has a built-in powerful neural network processor, supports convolutional neural computing and deep learning noise reduction, and has strong echo cancellation and environmental noise suppression capabilities 2. It supports adding command words through software, with a recognition rate of up to 99%, and supports Chinese and English entries. You can easily play with Al voice interaction without any basic knowledge 3. The voice module has multiple interfaces on board. You don't need to have a deep understanding of the principles of voice recognition. You can easily generate firmware through the supporting software and update the firmware through the Type-C interface 4. In addition, the module also provides serial port interface and IIC interface, which supports voice interaction projects with control platforms such as STM32, MSPMO, and Raspberry Pi 5. We have preset 110+ voice interaction word libraries, provided detailed usage tutorials, firmware modification tutorials, and burning tools to accelerate project development, and are an ideal choice for embedded voice projects Due to different batches, there may be differences in product appearance, color, and printed text, which will not affect the use.
