The Design and Implementation of a Speech Keywords Retrieving Application Based on Microsoft Speech SDK

LIN Qian, OU Jian-Lin, CAI Jun (Department of Cognitive Science, Xiamen University, Xiamen 361005, China)  
The design and implementation of a speech retrieving system which is based on continuous speech recognition techniques is reported. The application system is developed with Microsoft Speech SDK (SAPI). It can retrieve audio files containing a predefined set of keywords from the corpus in batch processing and can properly mark all recognized keywords, therefore, the sentences containing thekeywords can be located in the speech sentences. The recognition language model is confined by the keywords retrieving grammar, which can be modified by generating dynamic grammar. The change of keywords in the application can be easily performed by updating the keywords retrieving grammar correspondingly. Furthermore, the speech command and control grammar is designed to facilitate the speech-command manipulation of the system.
