It has eight independent modules that specifically address different aspects of the acoustic signal (habitual pitch, maximum phonation time, pitch range, phonation/respiration control, amplitude perturbation, diadochokinetic rate, etc.).
Both modules have a set of pre-designed protocols, for example, the measurement of second formant transitions in the [i-u] vowel sequence or the analysis of the diadochokinetic rate (rate at which a predetermined sequence of syllables is performed).
On the other hand, in the alternating syllabic movements task, the participants had to repeat, as quickly as possible, the syllable [pa] during eight seconds after hearing the pattern given by the computer from the diadochokinetic rate evaluation protocol of the motor speech profile module.
The speech sample collected was recorded using the diadochokinetic rate protocol of the real-time pitch module.
The present study attempts to understand if there is a relationship between the morphology of the craniocervical system and speech articulation, particularly at the intelligibility level measured by diadochokinetic (DDK) speech performance in young university subjects with no relevant morbid history.
The first stage considered speech intelligibility level assessment by the diadochokinetic periodic variation coefficient (cpv) of speech measured as a percentage (normal DDK cpv: 6.006% [+ or -] 1.118%).
Finally, diadochokinetic speech performance scores were correlated with the postural variables by linear regressions.
The linear regression analysis demonstrated that the anteroposterior cranio-cervical rotation was statistically associated with speech intelligibility in such a way that subjects with posterior head-neck rotation showed a higher percentage of variability in syllable emission of diadochokinetic speech performance (Table 3 and Figure 4).
