Moreover, testing results based on speech signals stimulated by the International Affective Picture System (IAPS) database showed that the proposed method could be also used in emotion strength analysis.doi:10.1007/978-3-319-11555-9_7Hao Zhang...
5.short-time synthesis of speech,讲的是语音经过STFT等操作之后,如何恢复到时域信号.这里介绍了两种思路 1)利用滤波器组 核心思想是逐频点处理。 STFT定义: 重写为 从而 还原的时域信号: 这一操作过程等价于滤波器组 2)Overlap-and-Add Method for Short-Time Synthesis,重叠相加法 核心思想是逐帧处理:...

The theoretical basis for the representation of a speech signal by its short-time Fourier transform is developed. A time-frequency representation for linear time-varying systems is applied to the speech-production model to formulate a quasi-stationary representation for the speech waveform. Short-time...

A Digital short time autocorrelator for speech sounds has been described. A special feature of this instrument is that it utilises zero crossings of speech sounds and an interlacing type of integrator which enables the study of stationary and non-stationary portions in speech sounds. Correlatograms...
