Acoustic analysis of the singing and speaking voice in singing students

The singing power ratio (SPR) is an objective means of quantifying the sing er's formant. SPR has been shown to differentiate trained singers from nons ingers and sung from spoken tones. This study was designed to evaluate SPR and acoustic parameters in singing students to determine if the singer-in-t raining has an identifiable difference between sung and spoken voices. Digi tal audio recordings were made of both sung and spoken vowel sounds in 55 s inging students for acoustic analysis. SPR values were not significantly di fferent between the sung and spoken samples. Shimmer and noise-to-harmonic ratio were significantly higher in spoken samples. SPR analysis may provide an objective tool for monitoring the student's progress.
