Mikroe SpeakUp clicks

Mikroe SpeakUp clicks are speech recognition click boards that recognize more than 200 separate voice commands. The standard click has onboard STMicroelectronics STM32F415RG (Arm® Cortex® M4) MCU that instantly carries out those commands. The SpeakUp 2 click features a single onboard FTDI FT900 MCU instead of two chips to process sound and interpret voice commands. Mikroe SpeakUp clicks are easy to configure and learn from scratch to understand commands spoken in any language. Using a simple interface on a computer, a word or phrase (up to 5s) can be recorded and assigned to an instruction. The speech-recognition capabilities firmware is based on the DTW algorithm, which turns talk into action almost instantly.
