This work presents the initial results of a study examining the spherical directivity and formant analysis of the Greek singing voice. The study aims to contribute to vocal production research and to the design of simulation, auralization, and virtual reality systems with applications involving speech and music. Unlike previous works focusing mainly on the horizontal plane, this study reports results on three elevation angles (+30°, 0°, and -30°). Six professional singers in Greek Classical and Byzantine music were recorded signing in a sound-treated space using a 29-microphone array mounted on a semi-spherical thin-shell structure. The collected dataset consists of short song excerpts and vowel sounds at different pitches. Directivity results across all elevation angles are reported based on overall and per third-octave band RMS levels. Formant analysis of the five Greek vowel sounds is also introduced.
