This paper describes the development and
validation of an Embedded IsolatedWord Recognition System
(IWR) for the Argentinian Spanish language, implemented on
the STM32F4-Discovery platform. Its front-end extracts Mel
Frequency Cepstral Coefficients (MFCC), while its classification
step is based on the Dynamic Time Warping (DTW) algorithm.
Since the system was conceived as a base platform for the
research and development of speechbased command and control
applications, it was designed to be modular and to meet real-time
performance.
