“…In a single dysarthric speaker only the respective rating exceeded the normal range. These observations are in accord with previous studies [4,6] indicating a predominantly strained-strangled voice quality of various degrees in the chronic stage of TBI dysarthrophonia. With regard to acoustic data, SPI did not differentiate between groups.…”

“…Consequently, a broad spectrum of speech and voice disorders has been noted in these patients [1][2][3][4][5]. Besides compromised articulation [3,4], individuals suffering from TBI sequelae frequently exhibit perceived dysphonia [2,4,6]. In the early postinjury stage, the majority of patients experience a weak and breathy voice often concomitant with increased pitch.…”

“…In the early postinjury stage, the majority of patients experience a weak and breathy voice often concomitant with increased pitch. During further follow-up, harsh and strained-strangled voice quality, pitch breaks, tremolo, occasional diplophonia and intermittent breathiness have been observed [1,4,6,7]. However, auditoryperceptual evaluation of voice abnormalities may cause several problems.…”

We tested the applicability of the Goettinger Hoarseness Diagram (GHD) for quantitative evaluation of voice disorders after severe traumatic brain injury (TBI) and compared the obtained data with those from established voice analysis systems such as the Multi-Dimensional Voice Program (MDVP), electroglottography (EGG) and perceptual ratings using sustained vowel productions from 10 patients with TBI dysarthrophonia at late stages postinjury and of 10 healthy control speakers. Statistical analyses revealed significant intergroup differences with respect to various acoustic and perceptual measures, i.e., irregularity component, noise component, noise-to-harmonic ratio, shimmer, jitter, roughness, creakiness, strained-strangledness, hypernasality. By contrast, the considered EGG estimates, i.e., open quotient and speed quotient, did not allow for separation of patients and controls. In addition, the two GHD components exhibited close correlations to perceived roughness and creakiness, on the one hand, and breathiness and, to some degree, nasality, on the other, whereas the MDVP parameters failed to differentiate between these two perceptual modes of phonation.

“…The observed vowels appeared in natural word context, each of them being tense, monophthong and in stressed position, namely [u:] [Vogel and von Cramon, 1982a]. The patients were examined at 3-weekly intervals on average, beginning with the end of mutism.…”

The frequencies of the first two formants of three German vowels in word context were determined by a formant tracking routine for 8 male subjects with closed head trauma. A centralized formant pattern was found to characterize vowel articulation in traumatic dysarthria. Different degrees of severity could be assessed and the process of recovery was described by the parameter ‘formant triangle area’. An interpretation in articulatory terms is given and the results are discussed in the light of articulatory models.

Vowel Distortion in Traumatic Dysarthria: Lip Rounding versus Tongue Advancement

Formant analysis of tense, high, German vowels was performed to the end of obtaining information about the role of insufficient lip rounding in distorted vowel production of 8 traumatic dysarthrics. A comparison was made between two allophones of /y/ in different consonantal contexts. Noticeable undershoot in lip rounding or protrusion proved to occur in a context of conflicting labial gestures. Where the articulatory realization of a CVC sequence required gross tongue movements, a lingual undershoot resulted as the prevailing deficit. No evidence for dyscoordinative defects was obtained from the results.
