Abstract

The invention discloses a spoken language dialogue management system which comprises a voice recognizer, a language understanding unit, a dialogue manager, a language generation unit, a voice synthesizer, a context guidance information generator and a strategy learning unit. In addition, the invention further discloses a spoken language dialogue management method. By the adoption of the technicalscheme, the dialogue manager maintains dialogue state information in the dialogue process, the system generates context guidance information according to the current dialogue state information and dynamically guides the voice recognizer to better recognize natural language possibly used by a user in the current context, and the voice recognition accuracy is greatly improved; and the speech recognizer does not need to prepare training corpora in a specific field in advance and train language models related to the field, but dynamically adjusts the language models according to different contexts, so that the workload of training the language models in advance is reduced, and the production efficiency of a man-machine conversation system is improved.

Description

technical field [0001] The invention relates to the technical field of man-machine dialogue, in particular to a spoken dialogue management method and system. Background technique [0002] Spoken Dialog System (SDS for short) interacts with users in the form of speech and provides users with specific services; a spoken dialog system usually consists of modules such as speech recognition, language understanding, dialogue management, language generation, and speech synthesis . In the spoken dialogue system, Dialog Management (DM for short) and Automatic Speech Recognition (ASR for short) are two independent modules. Among them, the dialogue management module is the core module in the oral dialogue system. Its front-end module converts the user's input into a certain formal semantic expression. On this basis, the dialogue management module determines the formal semantic expression of the next system output; output The formal semantic expression of is transformed into some outp...
