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 of the formant frequencies were clearly dependent on the vowel quality only for the formants F2 and F3. They were practically independent of the vowel quality for F4 (spoken and sung vowels) and F5 (sung vowels), 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 speaking voices with regard to this phonatory feature.
