纵摇周期
Examples
- The algorithm adopts frequency partition to estimate the range of pitch period , improving the computational speed
该算法采用频域分块估计候选基音周期的范围，提高了算法的计算速度。 - The arithmetic searches for the least central offset through partition speech sub - band and confirms pitch period of the transition sound
该算法主要通过划分语音子带来搜索最小中心偏移量，较准确地确定过渡音的基音周期。 - The results show that the method using bias function and time - domain clipping to search pitch period can overcome shortcomings of the traditional , reduce false decision and raise the estimation precision
研究结果表明：采用所提出的中心偏离函数和时域削波方法相结合来搜索基音周期，能够有效地克服传统方法的不足，降低误判率，提高基音周期的估计精度。 - But it is not the same with surd or the alternation of sonant and surd . on the base of the acoustics , a whole linear time - varying discrete speech produce model is established through anatomising the factors including track , driving source and lip eradiation the mechanism of speech in this paper , and we draw a conclusion that the time between glottal closure is pitch period
本文从声学理论出发，剖析了语音产生的机理，综合考虑声道、激励源和嘴唇辐射三方面的因素，建立了一个完整的、线性的和时变的语音产生的离散系统模型，得出两次声门闭合事件之间的时间间隔就是基音周期的结论。 - The paper ’ s main works are as follow : ( 1 ) several methods of getting pitch period are researched in details . according to the real - time demand for the systems , the methods for pitch searching are simplified as follow : after searching the peak value point every third point within pitch range , search the peak value point every point near the current peak value point
( 1 )研究了基音周期的求取方法,并根据系统的实时要求,将逐点搜索基音周期的方法简化为粗细法,即在基音周期范围内隔点搜索相关函数最大峰值点,然后在此时得到的最大峰值点附近继续搜索,将最后得到的峰值点作为基音周期值。
