| Abstract: | This paper provides the design of an embedded speech recognition module based on ARM. The system core is STM32F103C8T6, a 32-bit processor based on ARM Cortex-M3 core produced by STMicroelectronics. The center of this module is the dialogue management unit. The module contains a hardware unit based on LD3320 which is used for speech recognition. The real time operating system μC/OS-II is used for multitask scheduling and the operation of peripheral devices. A number of validations based on experimental data show this module has advantages of real-time, high recognition rate and high stability. |
