- 争对移动声源采用波束形成进行语音增强,提出一种约束子带波束形成算法。其波束形成器基于一个软约束,其目的是要使波束指向特定的区域即声源方向。而其核心在于首先要进行声源定位,获得尽量准确的方位信息,然后构造软约束条件,用于波束形成。且在此过程中不断跟踪声源的移动情况。在构造的约束条件中,需要知道声源的二维信息,即与麦克风阵列的距离和方向角,“软”体现在对距离和方向角的确定都是在一定范围内的,有待进一步更正。-Between the mobile sound source using beamform

- 基于互相关函数,采用求和广义互相关函数(summed-GCC)法用于机器人系统平台。由于采用不同的映射函数(mapping functions),GCC法在该平台下,只需三个麦克风即可进行三维定位,突破了基于TDOA法进行三维声源定位最少需4个麦克风的限制-Based on cross-correlation function, using generalized cross-correlation function sum (summed-GCC) method for the robot s

matlab
- 语音信号进行分析、处理和设计。用MATLAB做变声器的原理是通过改变输入声音频率,进而改变声音的音色、音调,使输出声音在感官上与原声音不同。变声器是借助对声音音色和音调的双重复合改变,实现输出声音的改变。通过自己发声,共振峰频率的改变是基于重采样实现的-Speech signal analysis, processing and design. MATLAB do voice-changer works by changing the input frequency of the sound,

Music-synthesis
- Matlab能够通过sound函数来实现演奏歌曲,而且音调的高低是和频率有关,所以我们在进行音乐合成时需按音调来查所对应的频率,再按曲谱控制节奏长度,再利用sound函数播放由不同频率的正弦波合成的声音,于是就可以利用Matlab演奏歌曲了。-Music synthesis
