A Tool for Cutting Large Speech Corpora: HCI4CS

摘要

There are two methods to cut large speech corpora, include traditional manual segmentation and machine automatic segmentation. The quality of segmentation can be controlled easily using traditional manual segmentation. However, the shortcomings of manual segmentation were also obviously such as inefficiency, high cost. As we all know, the method of machine automatic segmentation has the advantage of high efficiency, but the fussy work to find cutting error can't be omitted. Thus, this paper developed a tool of human-computer interaction for cutting speech corpora (HCI4CS), which provides segment algorithm, parameter to control, modifying the error of automatic segmentation results and generates labeling files for HTK toolkit. The research object was one thousand speeches of Primi. Using HCI4CS, a person with low cognitive competence about cutting speech corpora can achieve nearly one hundred percent accuracy.
