Abstract

The invention provides a semantic parsing method and device for voice, and the method comprises the steps: obtaining a plurality of text recognition results of voice data, and phoneme recognition results corresponding to the text recognition results; obtaining a target recognition result with the highest confidence degree from the plurality of text recognition results; determining a domain classification result to which the voice data belongs according to the target recognition result; and in the preset text field to which the voice data belongs, determining the music name of the voice data according to the plurality of text recognition results and the phoneme recognition results corresponding to the plurality of text recognition results. The voice interaction system solves the problems that the music name recognition accuracy is low and the interaction success rate is relatively low, improves the music name recognition accuracy, and also improves the interaction success rate of a user during interaction in the music field.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a semantic analysis method and device for speech. Background technique [0002] In modern daily life, users usually like to call terminal devices, such as speakers and mobile phones, to play songs through the intelligent voice dialogue system. The above performance is unsatisfactory. Aiming at the technical problem of poor interactive success rate of song names in the music field in intelligent dialogue systems, the invention proposes to use the Lattice search path in the speech recognition decoder to output the phoneme-level N-Best recognition results with the highest confidence score, and then call semantic analysis, The edit distance algorithm of the phonemes is used to screen the final analysis results to improve the success rate of interaction in the music field. [0003] In the existing speech dialogue system, the natural speech audio data from the user is obtained from...
