Splice out the voiced plosive “b” in theword “be” and synthesize aword with an increase in the voice onset time of the “b.” What is the perceptual effect? Is it possible to transform the voiced plosive “b” to the unvoiced plosive “p” with this change in the voiced onset time? Consider attributes such as vocal cord vibration and aspiration. (In splicing, display the waveform and spectrogram of the word “be” and use the MATLAB function ginput.m.) Optional: If your transformed sound does not sound like a “p” then, again considering vocal cord vibration and aspiration, make a more accurate transformation.

三次样条插值函数边界条件由实际问题对三次样条插值在端点的状态要求给出.以第1边界条件为例,用节点处二阶导数表示三次样条插值函数,用追赶法求解相关方程组.通过Matlab编制三次样条函数的通用程序,可直接显示各区间段三次样条函数体表达式,计算出已给点插值并显示各区间分段曲线图.(Cubic spline interpolation function from the real problems of boundary conditions cubic spline interpolation is required to give the state of the endpoint. Boundary conditions in the first example, the second derivative with node represents a cubic spline interpolation function, solving equations associated with catch-up method group. preparation of common procedures cubic spline function through Matlab, can directly display each range segment cubic spline function body expression, to the point of interpolation has been calculated and displayed for each sub-interval graphs.)
