Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: ,  describe and review our recent development of hands-free speech dialogue system which is used for railway station guidance. In the application at the real railway station, robustness against reverberation and noise is the most essential issue for the dialogue system. To address the problem,  introduce two key techniques in our proposed hands-free system; (a) speech dialogue system construction with real speech database collection and language/acoustic model improvement, and (b) microphone array preprocessing using blind spatial subtraction array which can solve the reverberation-naiveness problem inherent in conventional microphone arrays. The experimental assessment of the proposed dialogue system reveals that our system can provide the recognition accuracy of more than 80% under realistic railway-station conditions.
