Research and implementation of voice interaction system based on PC in intelligent space

This paper presents the design and implementation of voice interaction system based on PC in service robots intelligent space. Microsoft Speech SDK 5.1 and VoiceText are used for speech recognition and speech synthesis, respectively. The SQL Server 2000 is adopted to design dialogue base of dialogue management module. After getting information from intelligent space, intelligent space decision support system, which is on the server in service robots intelligent space, updates the XML grammar file dynamically for multiple scenes. According to the XML grammar file, speech recognition module works. If the recognition result is got, 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 if one exists to equipment 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.
