Voice Recognition


The Voice Recognition solution is implemented with i2s (inter-ic sound) and enables a high recognition rate under noisy environment conditions using noise suppressor technology. Voice commands are recognised by the i2s communication and mcu will respond over the external speaker through dac.

Cyberon Dspotter is a local voice trigger and command recognition solution with robust noise reduction that consumes very low resources and provides high-accuracy performance. It runs on ramcu family and supports multiple languages as well as many connectivity functions and security capabilities depending on the selected MCU.
