中文摘要 | 連續語音的音調辨認(tone recognition)對語音辨認器之準確性影響甚大,由於國語音調中一、二聲,原本就比較容易混淆,再加上背景雜訊及電話通道效應之干擾,音調辨認在目前仍有許多瓶頸有待克服,而基週軌跡偵測(detection of pitch contour)的準確性則攸關音調辨認器之成效,本文提出一種循環式區域峰值偵測法(iterative local peak detection method, ILPD)來偵測基週的軌跡。 |
英文摘要 | The detection of pitch contour for tone recognition of Mandarin speech is a very important topic. Due to the influences of background noise and channel effect, the detection of pitch contour is still a problem to be solved. In this paper, we propose an iterative local peak detection (ILPD) method and evaluate its effectiveness for speech tone recognition in a noisy environment. |
