Automatic voice assessment is often performed using sustained vowels. In contrast, speech analysis of read-out texts can be applied to voice and speech assessment. Automatic speech recognition and prosodic analysis were used to find regression formulae between automatic and perceptual assessment of four voice and four speech criteria. The regression was trained with 21 men and 62 women (average age 49.2 years) and tested with another set of 24 men and 49 women (48.3 years), all suffering from chronic hoarseness. They read the text 'Der Nordwind und die Sonne' ('The North Wind and the Sun'). Five voice and speech therapists evaluated the data on 5-point Likert scales. Ten prosodic and recognition accuracy measures (features) were identified which describe all the examined criteria. Inter-rater correlation within the expert group was between r = 0.63 for the criterion 'match of breath and sense units' and r = 0.87 for the overall voice quality. Human-machine correlation was between r = 0.40 for the match of breath and sense units and r = 0.82 for intelligibility. The perceptual ratings of different criteria were highly correlated with each other. Likewise, the feature sets modeling the criteria were very similar. The automatic method is suitable for assessing chronic hoarseness in general and for subgroups of functional and organic dysphonia. In its current version, it is almost as reliable as a randomly picked rater from a group of voice and speech therapists.

The article deals with an analysis focused on the expectations and attitudes to the diagnostics and intervention for people with symptomatic speech disorders, with an emphasis on the autism spectrum disorders, from the point of view of the education of students of speech and language therapy (logopaedics) as a part of the special education study programme. Special attention is paid to overlapping with the assessment of the pragmatic language level of communication and infl uencing it through speech and language therapy approaches. The connection with the modern concept of speech and language therapy in the pro-inclusive approach as well as in the context of preparation for collaborative transdisciplinary practice is discussed.

Cílem práce bylo programově využívat potenciál rodiny v terapii poruch řeči. V předloženém článku popisuji svá pozorování a zkušenost v souvislostech s literárními zdroji. Vycházím z metody videotréninku a z rodinné terapie. Převážně intuitivní, neuvědomovaný proces (1), v němž rodiče dětem předávají schopnost řeči, lze podrobit mikroanalýze. Společným rozborem obrazu se lze terapeuticky dotknout podvědomých vodítek, jimiž se řídí rodičovské chování k dítěti. Ve foniatrické ambulanci jsem u 28 rodin užila videotrénink v terapii rozličných poruch řeči. Základem práce je zpomalená a zastavovaná videonahrávka a rodinně terapeutický přístup. Pracujeme na kontaktu, naladění (tuning in), příjmu iniciativ. Proces předávání řeči podrobujeme mikroanalýze. Ukazuje se, že způsob interakce rodičů a stav vývoje dětské řeči spolu souvisí cirkulárně. Zvažuji vztah tradované potřeby stimulace vývoje řeči a přestimulování (overstimulating). Pracuji s tím, že předávání řeči dítěti rodiče převážně dělají nevědomě. Má-li dítě poruchu řeči, je užitečné, aby rodiče svou kompetenci posílili zkušeností z mikrovideoanalýzy interakce. Jazyk videotréninku navíc skýtá možnost komunikovat mezi profesionály svou zkušenost s vlivem rodiny na vývoj řeči dítěte.
The work was intended to take advantage of the family potential in the therapy of speech disorders. In a phoniatric outpatient office the authors employed video training in the therapy of various speech disorders. The author's experience has been described. The work was based on a slowed down and stopped video recording and the family-based therapeutic approach. The tactic makes use of the contact, tuning in and acceptance of the family initiative. The process of speech transfer is subjected to microanalysis. It has become apparent that the mode of interaction of the parents and the state of development of the child's speech is in a circular connection. The author considers the relation of traditional need of stimulation of speech evolution and overstimulation. The author maintains the hypothesis that the speech transfer from the parents is mostly unintentional. If the child suffers from a speech disorder, it becomes useful for the parents to improve their competence by experience from micro video analysis of interaction. The langue of video-training, moreover, provides the opportunity of communication between professionals by their experience in the influence of family on the evolution of the child's speech.

It is currently unknown whether speech and limb motor effectors in Parkinson's disease (PD) are controlled by similar underlying brain processes. Based on computerized objective analysis, the aim of this study was to evaluate potential correlation between speech and mechanical tests of upper limb motor function. Speech and upper limb motor tests were performed in 22 PD patients and 22 healthy controls. Quantitative acoustic analyses of eight key speech dimensions of hypokinetic dysarthria, including quality of voice, sequential motion rates, consonant articulation, vowel articulation, average loudness, loudness variability, pitch variability, and number of pauses, were performed. Upper limb movements were assessed using the motor part of the Unified Parkinson's Disease Rating Scale, contactless three-dimensional motion capture system, blinded expert evaluation, and the Purdue Pegboard Test. Significant relationships were observed between the quality of voice assessed by jitter and amplitude decrement of finger tapping (r = 0.61, p = 0.003), consonant articulation evaluated using voice onset time and expert rating of finger tapping (r = 0.60, p = 0.003), and number of pauses and Purdue Pegboard Test score (r = 0.60, p = 0.004). The current study supports the hypothesis that speech impairment in PD shares, at least partially, similar pathophysiological processes with limb motor dysfunction. Vocal fold vibration irregularities appeared to be influenced by mechanisms similar to amplitude decrement during repetitive limb movements. Consonant articulation deficits were associated with decreased manual dexterity and movement speed, likely reflecting fine motor control involvement in PD.

BACKGROUND AND OBJECTIVE: Hypokinetic dysarthria (HD) is a frequent speech disorder associated with idiopathic Parkinson's disease (PD). It affects all dimensions of speech production. One of the most common features of HD is dysprosody that is characterized by alterations of rhythm and speech rate, flat speech melody, and impairment of speech intensity control. Dysprosody has a detrimental impact on speech naturalness and intelligibility. METHODS: This paper deals with quantitative prosodic analysis of neutral, stress-modified and rhymed speech in patients with PD. The analysis of prosody is based on quantification of monopitch, monoloudness, and speech rate abnormalities. Experimental dataset consists of 98 patients with PD and 51 healthy speakers. For the purpose of HD identification, sequential floating feature selection algorithm and random forests classifier is used. In this paper, we also introduce a concept of permutation test applied in the field of acoustic analysis of dysarthric speech. RESULTS: Prosodic features obtained from stress-modified reading task provided higher classification accuracies compared to the ones extracted from reading task with neutral emotion demonstrating the importance of stress in speech prosody. Features calculated from poem recitation task outperformed both reading tasks in the case of gender-undifferentiated analysis showing that rhythmical demands can in general lead to more precise identification of HD. Additionally, some gender-related patterns of dysprosody has been observed. CONCLUSIONS: This paper confirms reduced variation of fundamental frequency in PD patients with HD. Interestingly, increased variability of speech intensity compared to healthy speakers has been detected. Regarding speech rate disturbances, our results does not report any particular pattern. We conclude further development of prosodic features quantifying the relationship between monopitch, monoloudness and speech rate disruptions in HD can have a great potential in future PD analysis.

An experiment was carried out to determine whether the level of the speech fluency disorder can be estimated by means of automatic acoustic measurements. These measures analyze, for example, the amount of silence in a recording or the number of abrupt spectral changes in a speech signal. All the measures were designed to take into account symptoms of stuttering. In the experiment, 118 audio recordings of read speech by Czech native speakers were employed. The results indicate that the human-made rating of the speech fluency disorder in read speech can be predicted on the basis of automatic measurements. The number of abrupt spectral changes in the speech segments turns out to be the most appropriate measure to describe the overall speech performance. The results also imply that there are measures with good results describing partial symptoms (especially fixed postures without audible airflow).
