Statistical distributions of speech for various languages
Chaslav V. Pavlovic, Mario Rossi, Robert Espesser · The Journal of the Acoustical Society of America · 1990
Statistical distributions of speech spectral energy were obtained for Danish, German, Italian, English, and French. The variable whose distribution was analyzed is termed “perceived spectral energy.” It represents the energy of speech contained within a band 1 Hz wide at the output of an exponential time window. Various window time constants were used in the analysis. Speech material was obtained from the EUROM. O database. The results indicate that there are no significant differences between the languages. Therefore, the normative values can be specified across the languages. However, significant sex differences are found and norms are given for each sex. Finally, these distributions will be compared to those of synthetic speech.
