Opis:
The goal of this research is to find a set of acoustic parameters that are related to differences between Polish and Lithuanian language consonants. In order to identify these differences, an acoustic analysis is performed, and the phoneme sounds are described as the vectors of acoustic parameters. Parameters known from the speech domain as well as those from the music information retrieval area are employed. These parameters are time- and frequency-domain descriptors. English language as an auxiliary language is used in the experiments. In the first part of the experiments, an analysis of Lithuanian and Polish language samples is carried out, features are extracted, and the most discriminating ones are determined. In the second part of the experiments, automatic classification of Lithuanian/English, Polish/English, and Lithuanian/Polish phonemes is performed.

Opis:
Although the emotions and learning based on emotional reaction are individual-specific, the main features are consistent among all people. Depending on the emotional states of the persons, various physical and physiological changes can be observed in pulse and breathing, blood flow velocity, hormonal balance, sound properties, face expression and hand movements. The diversity, size and grade of these changes are shaped by different emotional states. Acoustic analysis, which is an objective evaluation method, is used to determine the emotional state of people’s voice characteristics. In this study, the reflection of anxiety disorder in people’s voices was investigated through acoustic parameters. The study is a case-control study in cross-sectional quality. Voice recordings were obtained from healthy people and patients. With acoustic analysis, 122 acoustic parameters were obtained from these voice recordings. The relation of these parameters to anxious state was investigated statistically. According to the results obtained, 42 acoustic parameters are variable in the anxious state. In the anxious state, the subglottic pressure increases and the vocalization of the vowels decreases. The MFCC parameter, which changes in the anxious state, indicates that people can perceive this situation while listening to the speech. It has also been shown that text reading is also effective in triggering the emotions. These findings show that there is a change in the voice in the anxious state and that the acoustic parameters are influenced by the anxious state. For this reason, acoustic analysis can be used as an expert decision support system for the diagnosis of anxiety.

Opis:
In this paper, we report the results of an experimental study of the acoustic and articulatory features of the gemination in Modern Arabic language, pronounced by Algerian speakers. To extract the feature characteristics, we have carried out an acoustic analysis by computing the values of frequency formants, energy and durations of the consonants and subsequent vowels in the various [VCV] and [VCgV] utterances (Cg: geminate consonant). For the articulatory analysis, a range of kinematics parameters were analyzed from the phoneme productions including movement trajectories, distance, velocity, and duration of tongue movements. Among the most important results, we note a longer duration of the vowel following a geminate consonant, a decreasing in levels of F1 and F2 formants and a rising in level of F3 formant of this vowel.

Opis:
Speech emotion recognition is an important part of human-machine interaction studies. The acoustic analysis method is used for emotion recognition through speech. An emotion does not cause changes on all acoustic parameters. Rather, the acoustic parameters affected by emotion vary depending on the emotion type. In this context, the emotion-based variability of acoustic parameters is still a current field of study. The purpose of this study is to investigate the acoustic parameters that fear affects and the extent of their influence. For this purpose, various acoustic parameters were obtained from speech records containing fear and neutral emotions. The change according to the emotional states of these parameters was analyzed using statistical methods, and the parameters and the degree of influence that the fear emotion affected were determined. According to the results obtained, the majority of acoustic parameters that fear affects vary according to the used data. However, it has been demonstrated that formant frequencies, mel-frequency cepstral coefficients, and jitter parameters can define the fear emotion independent of the data used.

Opis:
The aim of the article is an acoustic description of German vowel elongation during live sports commentary. It is not about long vowels that are in time relation to the other segments in the lexeme, but about those that, regardless of the quantity, have an additional duration (over 0.2 seconds) in a particular communication situation. The research material consists of two sports commentaries. The first concerns Germany‘s victory in the quarter-finals of the 2017 IIHF World Hockey Championship; the second - the gold medal won by Gesa Krause during the women‘s 3000 metres steeplechase at the 2018 European Athletics Championships.

Opis:
Choral singers are among intensive voice users whose excessive vocal effort puts them at risk of developing voice disorders. The aim of the work was to assess voice quality for choral singers in the choir at the Polish-Japanese Academy of Information Technology. This evaluation was carried out using the acoustic parameters from the COVAREP (A Collaborative Voice Analysis Repository For Speech Technologies) repository. A prototype of a mobile application was also prepared to allow the calculation of these parameters. The study group comprised 6 male and 19 female choir singers. The control group consisted of health non-singing individuals, 50 men and 39 women. Auditory perceptual assessment (using the RBH scale) as well as acoustic analysis were used to test the voice quality of all the participants. The voice quality of the female choir singers proved to be normal in comparison with the control group. The male choir singers were found to have tense voice in comparison with the controls. The parameters which proved most effective for voice evaluation were Peak Slope and Normalized Amplitude Quotient.

Abstract Vestibular voice includes participation of larynx structures which are absent in physiological process. Vestibular phonation may be desired when vocal folds are damaged as in paralytic dysphonia, or undesired in marginal hyperfunction. Vestibular voice may result from psychogenic dysphonia – phononeurosis. The aim of the study is perceptive evaluation of vestibular voice, objective larynx visualization, acoustic and aerodynamic examination. The study included 40 patients: 20 with vestibular voice, 20 with euphonic voice. Voice quality has been evaluated using perceptual GRBAS scale. Endoscopic and stroboscopic larynx examination used Endo-STROB-EL-Xion GmbH with visual tract. High-Speed Digital Imaging (HSDI) and High Speed (HS) camera registered true vocal folds vibrations. Acoustic evaluation of voice with DiagnoScope Specjalista, DiagNova Technologies included analysis of F0, Jitter, Shimmer, NHR, nonharmonic components. MPT has been analyzed. In examined group, hoarseness (95%), roughness (75%) and voice strain (55%) have been recorded. Endoscopy revealed edema of vestibular folds with dilation of vessels covering glottis. Stroboscopy and HSDI confirmed coexistence of hyperfunctional (95%) or paralytic (5%) dysphonia. Acoustic assessment revealed increase in Jitter, Shimmer, NHR and decrease in F0 and MPT. The vestibular voice is observed most frequently in women with hyperfunctional dysphonia (phononeuroses) or in paralytic dysphonia. Visualization techniques confirm the coexistence of vestibular folds hypertrophy and edema with vibration disorders. In the perceptual assessment, vestibular voice was hoarse, rough and strained. Acoustic examination showed increase of Jitter, Shimmer, NHR, presence of nonharmonic components and decrease of F0 and MPT.

More specifically, it compares distribution of two English categories - /I/ and /e/ relative to neighbouring Polish vowels. 43 participants recorded Polish and English vowels in a /bVt/ context. First two formants were measured at a vowel midpoint and plotted on a vowel plane. The results reveal that while a separate /I/ category is formed fairly effectively in Polish learners pronunciation of English, a category of /e/ is almost completely subsumed by a Polish vowel /ϵ/

The aim of this acoustic study is to analyse the phoneme [ṭ] produced by school children surgically operated on for the cleft palate or cleft lip, in order to examine their vocal characteristics, to provide speech therapists with numerous concrete analyses of voice and speech, to effectively support them and to prevent some serious outcomes on their psychological and academic development. The motivation for this study was mainly stemming from the difficulties that Algerian schoolchildren with clefts encounter in the pronunciation of this phoneme. To carry out the study, several acoustic parameters were investigated in terms of the fundamental frequency F0, the first three formants F1, F2, and F3, the energy E0, the Voice Onset Time (VOT), the durations [CV] and [V] of the subsequent vowel [a]. For the analysis, further important parameters in the field of pathological speech were deployed, namely the degree of disturbance of F0 (jitter), the degree of disturbance of intensity (shimmer) and the HNR (Harmonics to Noise Ratio). Results revealed disturbance in the values of F1, F2, and F3 and stability in the values of F0. Another important reported aspect is the increase in the value of the VOT due to the difficulties in controlling the plosives’ successive closure and release.

This study investigates the production of vowels in unstressed syllables by advanced German learners of English in comparison with native speakers of Standard Southern British English. Two acoustic properties were measured: duration and formant structure. The results indicate that duration of unstressed vowels is similar in the two groups, though there is some variation depending on the phonetic context. In terms of formant structure, learners produce slightly higher F1 and considerably lower F2, the difference in F2 being statistically significant for each learner. Formant values varied as a function of context and orthographic representation of the vowel.

Opis:
This paper used the plosives’ duration of preceding (DoPV) and following (DOFV) vowels to investigate the effect of bilingualism on the pronunciation difficulties for Arabic as an L1 and English as an L2. The subjects were divided into three groups; Arabic-English bilinguals who speak Arabic as an L1 (N: 15), Arabic monolinguals (N: 15), and English native monolinguals (N: 5). The participants had a reading test as they produced the target words in carrier sentences with five repetitions. The results showed that the plosives’ DoPV and DoFV for L1 and L2 had complicated interactions categorised into four types. 1- a unidirectional impact of L1 on L2, 2. a unidirectional impact of L2 on L1, 3. bidirectional effect, and 4. Free L1-L2 interference. The outcomes additionally revealed that the bilinguals faced production difficulties that included similar and dissimilar Arabic and English plosives. Besides, the bilinguals succeeded in producing DoPV in a native-like way for dis/similar plosives. Consequently, this paper assumed that the pronunciations’ difficulties are not necessarily associated with the dis/similarity in the context of L1-L2 interaction. This paper helps Arabic-English bilinguals in developing their pronunciation by highlighting the plosives’ pronunciation complexity.

Ocenia się, że dysartryczne zaburzenia mowy w chorobie Parkinsona występują u 70-90% chorych, a leczenie farmakologiczne przynosi niewielkie efekty. Celem pracy była analiza komputerowa wpływu postępowania logopedycznego na strukturę akustyczną dźwięków mowy w grupie chorych z rozpoznaniem choroby Parkinsona. Materiał stanowiło 10 chorych (6 kobiet, 4 mężczyzn, w wieku 59-75 lat, średnio - 68,2), z rozpoznaniem choroby Parkinsona i z zaburzeniami mowy o charakterze dysar-trycznym. Wszyscy byli leczeni preparatami L-dopy. Przeprowadzono u nich terapię z uwzględnieniem ćwiczeń fonacji, artykulacji; ukierunkowanych na zmniejszenie sztywności mięśni ust i twarzy oraz ćwiczeń oddechowych. W celu oceny skuteczności postępowania logopedycznego wykorzystano komputerową akustyczną analizę mowy, ze szczególnym uwzględnieniem następujących parametrów: selektywności poszczególnych elementów wypowiedzi, tempa oraz stabilności dźwięków mowy. W analizie akustycznej zastosowano programy komputerowe IRIS oraz Wavelab. Stwierdzono, że systematycznie stosowane postępowanie logopedyczne u pacjentów z rozpoznaniem choroby Parkinsona i towarzyszącymi zaburzeniami mowy o typie dysartrii wpływa na stabilizację wybranych parametrów akustycznych mowy oraz poprawę sprawności mowy, co znalazło potwierdzenie w akustycznej analizie komputerowej.
Dysarthria occurs in case of 70-90% of patients with Parkinson's disease (PD). Pharmacological treatment of this symptom is not effective enough. The aim of this work was the computer analysis of the influence of speech therapy on the acoustic structure of speech sounds in patients with Parkinson's disease. Material and methods: 10 patients (6 women and 4 men) aged from 59 to 75 years (mean age - 68.2) with PD and dysarthria were examined. All patients were treated by the L-Dopa and the logopedie examination was carried out. The administrated pronation and articulation exercises aimed to facial and oral muscle rigidity reduction. The breathing training was included in the therapeutic programme, as well. Computer speech analysis was applied for the evaluation of speech rehabilitation efficacy. Selectiveness of the individual parts of speech and stability of frequency estimation were analyzed using IRIS and Wavelab computer programs. Systematic logopedie therapy in PD patients with dysarthria influences the speech acoustic parameters and enables the speech efficiency improvement. Computer acoustic analysis allows to follow the therapy efficacy.

Opis:
This paper investigates the impact of bilingualism on the difficulties of pronunciation for both L1 (Arabic) and L2 (English). It assesses the production of stop sounds in Arabic and English through an acoustic analysis of stops' closure duration (henceforth CD), as pronounced by Arabic-English bilinguals whose L1 is Palestinian Arabic. Additionally, the paper aims to highlight the difficulties of pronunciation in both languages. Three groups of same aged adult subjects participated in the production tests; 1) Arabic-English bilinguals whose L1 is Palestinian Arabic, 2) Arabic-monolinguals, and 3) English-monolinguals. The stops in word-medial and final positions were included in closed syllables (CVC) in meaningful words inserted in carrier sentences. The results revealed that the CD of the interaction of stops was represented in four categories; 1) unidirectional effect of L1 on L2 that caused a foreign accent, 2) bidirectional influence resulting in L1-L2 interference, 3) unidirectional impact of L2 on L1, and 4) nativelikeness in both languages without language interference. In addition, the findings showed that bilinguals faced pronunciation challenges in both similar and dissimilar sounds. This paper is expected to initiate more comprehensive studies in the field of interaction between Arabic and English in the Arabic context.
