We synthesize singing voice by rule based on cepstral method. Higher accuracy of analysis and synthesis is required to synthesize singing voice, comparing to rule-based speech synthesis. In this paper, we propose a method of analysis and synthesis with high accuracy. Also, we express pitch patterns minutely by curves that close to natural pitch by using this method. We apply Fujisaki model and ...

The two dimensional with a triangular-lattice cross sectional pattern of elliptic air holes photonic crystal fiber (PCF) is investigated in detail by use of plan wave expansion (PWE) method. Using PWE method, the dependence of dispersion on structure parameters is calculated. We compared the dispersion relations between the circular air holes PCF and the elliptic one. We find that the flatter d...

Control oriented implementations of neural network models and memory-based models are developed and compared. These techniques model the spectral data from instruments as opposed to the physical sound production mechanism. Both model types are for real-time control and use controller inputs such as pitch, loudness, and brightness functions to produce frequencies and amplitudes for sinusoidal co...

In this Article dispersion characteristic of conventional optical waveguide with helical winding at core – cladding interface has been obtained. The model dispersion characteristics of optical waveguide with helical winding at core-cladding interface have been obtained for five different pitch angles. This paper includes dispersion characteristics of optical waveguide with helical winding, and ...

In this paper, we present a solid-core Silica-based photonic crystal fiber (PCF) composed of hexagonal lattice of air-holes and calculate the effective index and chromatic dispersion of PCF for different physical parameters using the empirical relations method (ERM). These results are compared with the data obtained from the conventional multipole method (MPM). Our simulation results reveal tha...

In this paper is described the procedure employed in order to obtain the Fundamental Frequency or Pitch of the Infant Cry Signal of 11 cases (children) with different pathologies. A sample of the normal behavior pattern of the pitch as a reference case is included. This paper presents a way to get the Rising Shifts of Pitch Frequency (RSPF), besides others features of it. The result obtained sh...

The purpose of this paper is to present an algorithmic pipeline for melodic pattern detection in audio files. Our method follows a two-stage approach: first, vocal pitch sequences are extracted from the audio recordings by means of a predominant fundamental frequency estimation technique; second, instances of the patterns are detected directly in the pitch sequences by means of a dynamic progra...
