Consistency of Fundamental Frequency and Perturbation in Repeated Phonations of Sustained Vowels, Reading, and Connected Speech

Abstract

The purpose of this study was to determine consistency of the acoustic measurement of fundamental frequency (f0) and f0 perturbation using the Visi-Pitch. Samples of speech including a reading passage, vowels, and spontaneous speech were recorded for 12 normal young adults (6 men and 6 women). The results indicated that test-retest reliability was highest for the reading passage. The measurements of fundamental frequency for reading and spontaneous speech were very similar, but vowel production was, on average, higher in frequency than the other contexts. Test-retest measures of perturbation using the Visi-Pitch did not have a high correlation coefficient. Perturbation measures must be interpreted cautiously because of the influence of frequency.

Respiratory and Laryngeal Function During Spontaneous Speaking in Teachers With Voice Disorders

“…The results of this study indicated that laryngeal function may be different during continuous speaking than during a sustained vowel. Results of previous research on acoustic differences (Brown Jr. et al, 1996;Fitch, 1990;Nittrouer et al, 1990) and differences in supraglottic activity (Stager et al, 2000) that are evidenced across speaking tasks support the task differences seen in this study.…”

“…Incidence of supraglottic activity varies across speaking tasks, and is lower during a sustained /i/ vowel than during several continuous speaking contexts (Stager et al, 2000). Several acoustic characteristics such as fundamental frequency and voice intensity are affected by speaking context, and often differ for sustained vowels as compared to continuous speech (Brown Jr., Morris, & Murry, 1996;Fitch, 1990;Nittrouer, McGowan, Milenkovic, & Beehler, 1990). The task differences in this study suggest that in addition to acoustic parameters and supraglottic activity, patterns of vocal fold vibration may differ for sustained vowels versus continuous speech.…”

Acoustic measurements and perceptual evaluation of hoarseness in children's voices

“…Analysing adult voices, Södersten & Hammarberg (1989) found that most perceptual parameters were more prominent in connected speech as compared to sustained vowels. Furthermore, with regard to test-retest reliability, reading a text has been found to yeild more stable data than both running speech and sustained vowel phonation (Fitch, 1990). Sederholm (1996) recently carried out a perceptual study of the same 50 voices as were analysed in the present investigation.…”

Relationship of the Cricothyroid Space with Vocal Range in Female Singers

“…Data from the National Center for Voice and Speech in the USA are shown in Figure 2.8. There have been a few studies on SFF in singers (Nadoleczny, 1923;Koufman & Blalock, 1988;Brown Jr, et al, 1991;Brown Jr, et al, 1993;Drew & Sapir, 1995;Morris, et al, 1995;Larsson & Hertegård, 2008) (Snidecor, 1951;Mysak, 1959;Schultz-Coulon, 1975;Horii, 1982;Hudson & Holbrook, 1982;Ramig & Ringel, 1983;Fitch, 1990;Traunmuller & Eriksson, 1994;Schiwitz, 2011).…”

“…There are many influences on SFF including subject selection criteria and subject variables ( & Hollien, 1963;Honjo & Isshiki 1980;Stoicheff, 1981;Alarcos et al, 1983;Mueller et al, 1984;Linville & Fisher, 1985;Linville, 1987;Pegoraro-Krook, 1988;Higgins & Saxman, 1991;Russell et al, 1995) professional training (McGlone, 1977;Watson & Hixon, 1985;Morris & Brown Jr, 1987;Brown Jr et al, 1988;Brown Jr et al, 1991;Brown Jr et al, 1993;Baken & Orlikoff, 2000;Brown Jr et al, 2000) task type (Mysak, 1959;Horii, 1975;Hudson & Holbrook, 1982;Ramig & Ringel, 1983;Britto & Doyle, 1990;Fitch, 1990;Murry et al, 1995;Zraick et al, 2000;Baker et al, 2008;Schiwitz, 2011) measuring method (Hirano, 1989;Morris & Brown Jr, 1996;Behrman, 2005) anthropometric indices (Bricker & Pruzansky, 1976;Lass & Davis, 1976;Lass et al, 1977;Lass, Barry, et al, 1979;Lass, DiCola, et al, 1979;Lass & Colt, 1980;Graddol & Swann, 1983;…”
