AN ANALYSIS OF PHONETIC DIFFERENCES BETWEEN GERMAN SINGING AND SPEAKING VOICES
Sigurd Rosenau · 1999
In this study an investigation of phonetic differences between singing and speaking voices is presented which focusses on vowel quality and the electroglottographic signal. It is based on the analysis of synchronous recordings of acoustic and electroglottographic signals of several singers that spoke and sung different German vowels at average speaking fundamental frequencies. Four different voice classes were considered ranging from bass to soprano. The analysis was done by determining qualitative differences of formant frequencies and the closed quotient between the spoken and sung vowels. It mainly showed that these differences are fairly independent of the voice class. The differences between the formant frequencies of spoken and sung vowels were clearly dependent on the vowel quality only for the formants F2 and F3 and generally insignificant for F1 . The differences of the values of the closed quotient were relatively small which suggests an influence of the singing voices on the...
