Single-Microphone Speech Recognition

The voice chip converts captured speech into commands and communicates with the MCU of an electronic control board or other devices via a serial port. Upon receiving commands, the MCU or device responds or controls accordingly. The MCU or device can also send commands to the voice chip for operations such as voice broadcasting. It supports offline natural speech and fixed vocabulary recognition, multi-intent understanding, echo cancellation, self-learning, and multiple wake word switching. Additionally, it provides SDK and documentation for developers to perform secondary development. Currently, this solution has been mass-produced and applied in various fields, including fans, clothes drying racks, heating tables, tea bars, lighting, and more.

Serial communication solution

Serial communication solution: As the simplest and fastest communication method, it can quickly add offline voice recognition function to your product.

• ☞Offline ASR serial communication solution：The most commonly used solution is to add voice control to household appliances, and add voice recognition and voice playback functions to products through data interaction of serial ports.

• Pure offline + Bluetooth serial port communication solution: A product application case that integrates Chipintelli’s voice chip with a Bluetooth chip to create a comprehensive solution featuring Bluetooth music, Bluetooth calling, and mini-programs.

• Command word self-learning solution development: Extracts deep acoustic features from speaker’s voice using deep neural networks, registers and stores them as voiceprint templates, allowing customer-customized voiceprint templates to replace default command word instructions.
