Simple Speech-to-Text on the '10 Cents' CH32V003 Microcontroller

Simple Speech-To-Text on the '10 cents' CH32V003 Microcontroller - brian-smith-github/ch32v003_stt

This program will read audio from an analog microphone and distinguish between the spoken digits 'zero' to 'nine', logging the results over a serial link. No hardware-multiply or hardware-divide - so audio processing routines have to be lean and fast to run within the 48MHz / 100fps timing constraints The code uses traditional (allbeit pared down) MFCC feature extraction, and simply compares buffered tensors of samples against pre-recorded spoken digits to get a 'best match'.
