The main advantage of the proposed approach is its ability to reach both of the user and the system goals more efficiently. The strategy that underlines our system is well adapted to the mobile applications since it involves effective spoken exchanges to reach the users' and system mutual goals. The proposed fram ework is built in order to use the Hidden Markov Models (HMMs) based CMU-Sphinx speech recognition engine f or mobile communications. To evaluate our approach a case-study in the M-trading field is considered. The analysis of the case study shows the efficiency ofour strategy in comparison with the usual ones. ©2009 IEEE.enPermission to reuse abstract has been secured from Institute of Electrical and Electronics Engineers Inc.Co-operation strategyDialogue managerM-commerceM-commerce applicationsMobile applicationsMobile communicationsSpeech recognition engineSpoken dialogueVirtual agentElectronic commerceHidden Markov modelsInformation technologyInnovationManagementManagersMobile telecommunication systemsSpeech recognitionConference PaperCopyright : 2009 IEEE.
