The SpeakUp click is a speaker dependent speech recognition accessory board, which also has the ability to run standalone (no external microcontroller needed). It can be programmed to recognize over 200 different voice commands, which the onboard STM32F415RG MCU can react to. It works by matching sounds with pre-recorded commands. The firmware is based on the DTW speech recognition alghoritm, which enables fast operation with instant recognition. Sound is received through an onboard microphone and then processed by a VS1053 IC with a built in stereo-audio codec. The SpeakUp comes with a dedicated software tool for easy configuration. The board is lined with 12 user programmable GPIOs for standalone functionality, and can also be connected to a mikroBUS host socket, with communcation via SPI, I2C or UART.
