While $F_0$ information obtained by Hough transform has been shown to be effective in speech recognition in noisy environment, it is difficult to use in real time applications because the computational costs for Hough transform is relatively high. This paper proposes an efficient $F_0$ extraction method using Hough transform. The number of frames perfoming Hough transform is reduced by reusing the voting values on the $m$-$c$ plane calculated in the previous frames. We performed the evaluation experiments using the Japanese Newspaper Article Sentences and the JEIDA-NOISE database. Improvement of word accuracy on average over all the noise conditions was 1.5 points. In comparison with our previous study, computational costs for $F_0$ extraction was reduced by 44.7\%. |
