摘要：This paper presents the design and implementation of voice interaction system based on ARM in service robots intelligent space. ARM Cortex-M3 core based STM32F103 is used for main controller. And real-time embedded operating system mu C/OS-II is used to schedule different tasks and manage peripheral devices. LD3320 and XFS4041CN are used for speech recognition and speech synthesis, respectively. Establish a dialogue set by defining the set of two-dimensional array, and then intelligent space updates the dialogue set dynamically via ZigBee wireless network for multiple scenes. If the recognition result is got by speech recognition module, dialogue management module will send corresponding texts to speech synthesis module, enabling text-to-speech output. At the same time, intelligent space decision support system will send corresponding commands to equipments by ZigBee. From lots of experiments and practical applications, we can conclude that voice interaction systems designed in the paper can gracefully satisfy the current request of voice interaction in service robots intelligent space, having great application value.
