Abstract: The present invention relates to a method for preparing hierarchically ordered structures of inorganic phosphate particles, homogeneously deposited on the surface of a phyllosilicate, which is characterized in that it comprises the following steps: a) obtaining an acid solution of precursor compounds of an inorganic phosphate; b) preparing a dispersion of particles of a phyllosilicate in aqueous medium and acidifying the phyllosilicate dispersion by adding at least one acid, thereby obtaining an acid dispersion; c) mixing the acid solution obtained in step a) with the dispersion obtained in step b); and d), with stirring, adding a base to the mixture obtained in step c) until the required pH value for precipitating the corresponding inorganic phosphate on the phyllosilicate particles has been achieved, resulting in a hierarchically ordered structure of homogeneously distributed submicrometric or nanometric inorganic phosphate particles supported on the phyllosilicate surface.

Abstract: The invention relates to a method for speech signal analysis, modification and synthesis comprising a phase for the location of analysis windows by means of an iterative process for the determination of the phase of the first sinusoidal component and comparison between the phase value of said component and a predetermined value, a phase for the selection of analysis frames corresponding to an allophone and readjustment of the duration and the fundamental frequency according to certain thresholds and a phase for the generation of synthetic speech from synthesis frames taking the information of the closest analysis frame as spectral information of the synthesis frame and taking as many synthesis frames as periods that the synthetic signal has. The method allows a coherent location of the analysis windows within the periods of the signal and the exact generation of the synthesis instants in a manner synchronous with the fundamental period.
