Sylvia Moosmüller an example of a monotonous change of formant frequencies. The period in question is put between the two cursors in the spectrogram window. The position “0” in the waveform zoom window refers to the left cursor in the spectrogram. The period in question does not enter the analysis. Vowel – semivowel, semivowel – vowel, and vowel – vowel 35 sequences were not analyzed for the same reason as put forward for vowel – liquid sequences. From the vowels selected for analysis, F1, F2, F3, F0, and duration measurements have been performed. Depending on the duration of the vowel, the measurement procedure described above rendered 20 – 150 measurements per vowel. This data was exported for further statistical analysis. Except where otherwise mentioned, the formant frequency contour of the whole vowel was analysed (i.e., transitions enter into the mean values). This method was chosen because vowels, especially when short, often expose no steady state portion. Therefore, an analysis relying solely on the steady state portion or the vowel midpoint would not produce reliable results. Figure 2.4 gives an example of a vowel with no steady state portion for F1 and F2: formants monotonously move from the bilabial plosive to the velar plosive (see also Chapter 5). The vowel in question is displayed between the two cursors in the spectrogram window. The waveform zoom window and the amplitude spectrum window refer to the right cursor position in the spectrogram. 35 For an analysis of quasi-homorganic vowel – vowel sequences in Austrian German see Moosmüller (1999). 24

Bottom panel: fundamental frequency. Next panel from bottom: waveform window. Third panel from bottom: spectrogram window. Left upper panel: waveform zoom window. Right upper panel: amplitude spectrum window. If necessary, formant frequency traces were corrected or aligned to the correct order. Figure 2.5 presents the calculated formant frequency movement and alignment in an uncorrected form. As concerns the vowel /i/ (between the cursors), the respective formants have been identified correctly. However, the movement of F3 is interrupted for quite a substantial part of the total duration of the vowel. STx provides several possibilities for editing and correcting.
