Description: ：Duffing振子相变对与参考信号频差较小的周期小信号具有敏感性，对白噪声和与参考信号频差较大的周期干扰信号
具有免疫力。利用语音的准周期性提出了一种基于混沌理论的语音端点检测新算法，讨论了如何利用Duffing振子的间歇混沌
特性来检测语音端点。将含噪语音作为Duffing振子的外部参考信号的摄动，根据系统相图是否改变来检测语音段和噪声段。
通过尺度变换并设计了振子阵列以检测频率范围较大的语音信号。实验结果表明，基于混沌的语音端点检测算法在低信噪比
下明显优于传统的能量语音端点检测法。-Duffing oscillator phase transform is sensitive to small signal that has tiny ~equency difference with the
referential signal，and immunes against random noise and larger interference signal that has larger frequency differ—
ence with the referential signa1．In this paper，a new method is proposed for endpoint detection based on chaotic the—
ory using the qusi—periodical characteristic of speech．How to test speech endpoint using intermittent chaos of Duffing
oscillator is discussed．There we take noisy speech as the perturbation of the referential signal of Duffing oscillators，
and we can test speech segments and noise segments according to phase trajectory．Oscillator array is designed and
connected with scale transform to detect the speech signal whose frequency range is wide． Experiments show that
chaotic method is superior to traditional energy method obviously under low SNR condition for endpoint detection．
