The information from this study helps to guide clinical and research applications of SAASP. The effects of analysis parameter manipulations on accuracy of formant-frequency measurements varied by SAASP, speaker group, and formant. In WaveSurfer manipulations did not improve formant measurements. Manipulations of default analysis parameters in CSL, Praat and TF32 yielded more accurate formant measurements, though the benefit was not uniform across speaker groups and formants. Smaller differences between values obtained from the SAASP and the consensus analysis implied more optimal analysis parameter settings. Formant frequencies were determined from manual measurements using a consensus analysis procedure to establish formant reference values, and from the four SAASP (using both the default analysis parameters and with adjustments/manipulations to select parameters). ![]() Productions of four words containing the corner vowels were recorded from four speaker groups with typical development (male and female adults, male and female children) and four speaker groups with Down syndrome (male and female adults and male and female children). This study systematically assessed the effects of select LPC analysis parameter manipulations on vowel formant measurements for diverse speaker groups using four trademarked Speech Acoustic Analysis Software Packages (SAASP): CSL, Praat, TF32, and WaveSurfer.
