Time is displayed on the x-axis, the y-axis indicates frequency and intensity levels. The darker shades inside the spectrogram represent speech, i.e. the syllable /pa/, the lighter or blank areas show the pauses in between the syllables (like the closure phase for the consonant /p/). (On-line version in colour.)and disordered speakers that had been identified perceptually by the listeners. There was also some suggestions that in at least some circumstances, particular dysarthric speech symptoms title= j.1399-3046.2011.01563.x including inappropriate duration, segmental articulation errors or changes in intensity and F0 modulation either influenced the outcomes on the metrics straight or affected listener perception of rhythm, as a result major for the mismatch between the two types of analyses. These findings have implications for the use of acoustic-based metrics to characterize speech functionality in disordered populations, suggesting that care requires to be taken in the interpretation of these benefits and additional analysis procedures may need to be employed to arrive at a valid characterization of a speaker's functionality. The lack of differentiation among groups by the rhythm metrics in activity 1 was unexpected, offered that speakers had been chosen around the basis that they perceptually presented with rhythmic deviance. The present findings contradict earlier studies which demonstrated excellent sensitivity of the investigated rhythm metrics to various kinds of speech impairments [20] too as considerable correlations amongst at the very least one of the measures applied here (nPVI-V) and perceptual ratings of disordered speakers title= s-0031-1280650 [28]. On the other hand, they confirm Kim et al.'s [27] findings, as these authors also failed to differentiate disordered from title= journal.pone.0023518 healthier speakers with their PVI measure. Modest sample size and intra-group variability are often cited as motives for lack of statistical significance, both of which might be mentioned to apply in this study. There's surely a possibility that a larger sample group would have resulted in much more affirmative group variations for the rhythm metrics. In addition, one could argue that the very repetitive nature from the activity may well have influenced outcomes in some way, major to a loss of distinction among speakers groups. The outcomes reported by Henrich et al. [28] could assistance this conclusion as in addition they observed that groups differed from one another in some but not other tasks. Irrespective of these explanations, the situation remains that there was a considerable mismatch between the acoustic and perceptual analysis. Extra importantly, this study identified numerous troubles that appeared to influence the way rhythmic deviations were captured by the metrics. These would apply even in situations where these metrics did highlight variations to healthful speakers, and it is thus significant to consider them in future research also as clinical practice. Two patterns in particular have been identified inside the sentence repetition at the same time because the spontaneous speech task: modifications to vowel duration and segment deletion. As currently described inside the Outcomes section, they each brought on alterations for the normal speech timing pattern, having said that, they could not be captured equally effectively by the metrics.
