Title:
SPEECH RECOGNITION METHOD FOR HUMAN-MACHINE INTERACTION OF SMART APPARATUS, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/140487
Kind Code:
A1
Abstract:
A speech recognition method for human-machine interaction of a smart apparatus and a system, pertaining to the technical field of speech recognition, and improving the accuracy of speech recognition by means of joint optimization training of intent detection and slot filling. The method comprises: performing word segmentation on speech data of a user's question to obtain an original word sequence, and generating a vector representation of the original word sequence by means of embedding processing; performing weighting processing on a hidden state vector hi and a slot context vector ci
S to obtain a slot label model yi
S; performing weighting processing on a hidden state vector hT and an intent context vector cI to obtain an intent prediction model yI; joining the slot context vector ci
S and the intent context vector cI by means of a slot gate g, and obtaining a transformed representation of the slot label model yi
S by means of the slot gate g; and constructing an objective function for joint optimization of the intent prediction model yI and the transformed slot label model yi
S, and performing intent detection on the speech data of the user's question on the basis of the objective function.
