Speaking Fundamental Frequency

The fundamental vocal frequency characteristics were measured from 50 male and 50 female Black 6-year-old children during prompted spontaneous speech. Boys had a mean fundamental frequency of 219.50 Hz, with a mean range of 134.80–298.70 Hz. Girls had a mean fundamental frequency (F 0 ) of 211.30 Hz and a mean frequency range of 137.60–297.50 Hz. No significant differences in mean or range values were found as a function of speaker sex. Nonsignificant relationships were found between physical variables of speaker height and weight and these F 0 measures for either sex and for the speaker group combined. The results of the present study were compared to previous research concerning the speaking fundamental vocal frequency of White children.

Speaking Fundamental Frequency

Speech samples from groups of White, African American, and Hispanic kindergarten-age children were compared on measures of mean speaking fundamental frequency (F o ), maximum and minimum speaking F o , pitch sigma, and speaking range (in semitones). Results indicate that there are significant differences between racial groups on measures of mean speaking F o and speaking range. In particular, the Hispanic children were observed to have increased mean speaking F O S in comparison with the African American children and reduced speaking ranges as compared to both African American and White racial groups. Results indicate that the speech-language pathologist must exercise discretion when assessing the speaking F o characteristics (particularly mean speaking F o and speaking range) of children from different racial groups.

Frequency Features

Selected characteristics were compared in the speech and voice of 28 patients treated with a supracricoid partial laryngectomy (SCPL) and of 14 normal adult laryngeal (NAL) speakers. Tape-recorded speech samples were measured for durational features with a stopwatch. Frequency features were analyzed with the Computerized Speech Lab and a multidimensional voice program. The SCPL speech proved comparable to NAL speech in average fundamental frequency. The SCPL speech and voice were statistically less efficient than NAL speech in fundamental frequency range, jitter, shimmer, noise to harmonics ratio, maximum phonation time, speech rate, and phrase grouping. The completion of an arytenoid cartilage resection did not statistically modify the duration and frequency features of SCPL speakers. Among SCPL speakers 1) the average fundamental frequency was statistically higher (p = .02) in patients who underwent a cricohyoidoepiglottopexy when compared to patients who underwent a cricohyoidopexy, 2) the maximum phonation time was statistically related to the patient's age (p = .002), and 3) the jitter and shimmer values were statistically related (p = .01 and p = .005) to the time elapsed since SCPL completion. Explanations and implications of these findings are discussed.

This study investigated the relationship between pathologic and normal speaking fundamental frequency characteristics (SFF) in a group of 80 male subjects. The subjects were divided into four groups of 20 (1) vocal fold paralysis, (2) benign mass lesion, (3) cancer of the larynx, and (4) normal. The results of this study indicate that SFF standard deviation and semitone range of SFF are significantly reduced for patients with vocal fold paralysis as compared with normals. The parameters of mean SFF, number of frequency shifts, and age failed to separate the normals from the three groups of pathologic subjects.
