In order to explain the term of sonority it is necessary to refer to the term of a timbre. This term is used to differentiate the sounds that have the same volume and height. It has significant impact on the personal perception of the sound. It is a subjective value, but there are known signal parameters influencing it. Sonority is one of characteristics of the timbre and this subjective characteristic is taken into consideration. The research is done in the context of singing. Sonority is the feature of a sonorous sound. It is considered as especially deep and resonant sound. Sometimes such voice is defined as rich and full in sound. According to the dictionary [1], sonorous voice is: rich, deep, ringing, resonant, full, rounded, sounding, loud, resounding, plangent. Sonorous voice is understood here as rich and full in sound and is claimed to be opposite to matt voice (according to the experts suggestion). To find the signal parameters relative to sonority some signal parameters were selected, calculated and the results were compared to the experts assessments of sonority feature in singing. The assessment has been done by five experts in the field of voice production. Sonority of voice A clear definition of sonority in singing (or a sonorous voice) is not easy to find. It is also hard to find some example investigations in this field. This is maybe because the phenomenon is strongly subjective. In the investigation on speaking voice quality [2] the author puts special emphasis on the vocal characteristics of sonority and ringing quality, as the essence of the term “resonant voice". In this article it is assumed that sonorous voice and ringing describe the same phenomena (and will be generally named by the term of sonority). In the conclusion the author indicates that sonority (among other perceptual characteristics) was well heard by judges. It is also interesting to register that the situation was a bit different w[...]
