Embodiment Construction

[0030] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] At first introduce a usage example of the present invention, promptly correct the recognition error process of handwriting input with the method of the present invention, as figure 2 as shown, figure 2 (a) It was wrongly segmented and identified as "Wangsha Station Tunnel Flower Link" (see figure 2 (b)), the user repeats "probability theory and random process" with voice, and after multi-channel fusion, the correct segmentation recognition result is obtained (see figure 2 (c)).

[0032] figure 2 An example, its specific implementation steps are as follows:

[0033] 1. Obtain the candidate set of handwriting recognition results by over-segmentation. The specific steps are:

[0034] 1) Suppose the sentence S is overcut into a sequence of frag...

Abstract

The invention pertains to the field of man-machine interaction, and particularly relates to a multichannel handwritten Chinese error correction method based on voice. The method repeats handwritten content by the voice and corrects handwriting identification error by adopting a mode which blends handwriting and the voice. The method calculates Levenshtein distance by cutting the handwriting into a plurality of segment sequences and simultaneously expressing both the handwritten and the voice with phonemes, and calculates divide and conquer blending cost, and the Chinese character cutting result with the lowest divide and conquer blending cost is the final cutting result. The core of the method is the multichannel blending of the handwritten and the voice, and the error of handwritten identification is corrected by utilizing the voice and adopting the method of the complementary of voice input and hand input.

Description

technical field [0001] The invention belongs to the field of human-computer interaction, and in particular relates to a voice-based multi-channel handwritten Chinese error correction method. Background technique [0002] Entering information into computers by handwriting is gradually becoming a widely used input method. Generally, written handwriting is recognized as text. However, due to frequent errors in handwriting recognition, the naturalness and efficiency of handwriting input are greatly affected (B. Suhm, B. Myers and A. Waibel, Model-based and empirical evaluation of multimodal interactive error correction, Proc. ACM CHI'99, pp.584-591, 1999). Although many studies have been devoted to improving the correct rate of handwriting recognition, it is still difficult to completely eliminate the recognition errors, so the system based on handwriting recognition must support the correction of recognition errors. The study found that in recognition-based systems, user sat...
