Description: 语音合成程序！psalo频域基音同步叠加方法。它首先对原始语音信号进行短时频域变换，得到短时谱和短时谱包络。短时谱除以短时谱包络得到声源短时谱，对声源短时谱的实部和虚部分别进行线性插值，就可以达到改变语音信号基频的目的，然后再进行频域反变换，可得到变换后的短时语音信号。短时谱包络部分也可以独立改变，以达到改变音色的目的。-speech synthesis procedures! Psalo frequency domain pitch synchronous superposition method. It is first of the original speech signal for short-time frequency domain transform, to be short-term and short-term spectral envelope spectrum. Short-term spectrum divided by the short-time spectral envelope of the sound source to be short-term spectrum of the sound spectrum of short-term real and imaginary parts of linear interpolation, they could change the voice-frequency signals to the end, then we will proceed to frequency-domain transform, Transform available after the short speech signal. Short-term spectral envelope can be independent of changes to achieve the objective of changing colors. Platform: |

Description: 用头相关传输函数卷积合成虚拟声的方法，我们将利用没有方位信息的单通道声音信号（可以是一段标准语音，也可以是音乐等其他类型的声音），通过信号处理的方法赋予其方位感。
人能听到声音是声音在空间中传播的结果，声音从声源到人耳鼓膜传播过程中发生了变化，这种变化可以看成是人双耳对声音的滤波作用，因此我们将声音从自由场传到鼓膜处的传输函数定义为头相关传输函数(HRTF, Head Related Transfer Function)，其对应的时域响应称为头相关冲激响应(HRIR, Head Related Impulse Response)。本实验用到的HRTF/HRIR数据库是由MIT Media Lab测量得到的。-Convolution with the head-related transfer function virtual sound synthesis approach, we will use the information without bearing single sound signal (can be a standard voice, can also be other types of music, sound), through signal processing methods to give its position sense.
One can hear the sound is sound in space, the spread of the sound the human ear from the sound source to spread the process of tympanic membrane changes, this change can be considered as one of the filtering effect of both ears to the voices, so we will sound from the spread to the tympanic membrane at the free field transfer function is defined as the head related transfer function (HRTF, Head Related Transfer Function), the corresponding time domain response is called head-related impulse response (HRIR, Head Related Impulse Response). The experiment used HRTF/HRIR database is measured by the MIT Media Lab s. Platform: |

Description: 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, and then change the sound of the tone, pitch, so that the output audio with the original sound in different senses. Voice Changer is the use of sound timbre and tone of the dual composite changes, realize the output sound changes. Through their own sound, formant frequency change is implemented based on resampling Platform: |
