The relationship between auditory processing disorder and articulation disorders
Auditory processing disorder (APD) may attribute to certain speech problems, as auditory processing plays a vital role in phonetic development during childhood. This research investigates the incidence of APD in individuals with misarticulations of the /r/, /s/, /k/, /θ/, /dʒ/, and /q/ speech sounds. These sounds represent different places of articulation, manners of articulation, and phonation.
A total of 51 participants with articulation disorders aged 6-18 years underwent conventional peripheral assessments, including otoscopic examination, immittance measurement, and audiometry. Central auditory processing was also evaluated using a battery developed by Frank Musiek.
Central auditory processing evaluations revealed abnormalities in 37 of 51 participants (72.55%). Correlations between various sound misarticulations and APD were identified: 69.5% for /r/, 40% for /s/, 80% for /k/, 100% for /θ/ and /q/, and 83.3% for /ʤ/.
The correlation between articulation disorders and APD varies depending on the specific sound affected. Further research is needed to establish clearer associations between different articulation disorders and APD. These findings underscore the importance of assessing central auditory system function in patients with articulation disorders before initiating speech therapy.

Impairment of Vowel Articulation as a Possible Marker of Disease Progression in Parkinson's Disease
The aim of the current study was to survey if vowel articulation in speakers with Parkinson's disease (PD) shows specific changes in the course of the disease.
67 patients with PD (42 male) and 40 healthy speakers (20 male) were tested and retested after an average time interval of 34 months. Participants had to read a given text as source for subsequent calculation of the triangular vowel space area (tVSA) and vowel articulation index (VAI). Measurement of tVSA and VAI were based upon analysis of the first and second formant of the vowels /α/, /i/and /u/ extracted from defined words within the text.
At first visit, VAI values were reduced in male and female PD patients as compared to the control group, and showed a further decrease at the second visit. Only in female Parkinsonian speakers, VAI was correlated to overall speech impairment based upon perceptual impression. VAI and tVSA were correlated to gait impairment, but no correlations were seen between VAI and global motor impairment or overall disease duration. tVSA showed a similar reduction in the PD as compared to the control group and was also found to further decline between first and second examination in female, but not in male speakers with PD.
Measurement of VAI seems to be superior to tVSA in the description of impaired vowel articulation and its further decline in the course of the disease in PD. Since impairment of vowel articulation was found to be independent from global motor function but correlated to gait dysfunction, measurement of vowel articulation might have a potential to serve as a marker of axial disease progression.

Acoustic Analysis of Changes in Articulation Proficiency in Patients with Advanced Head and Neck Cancer Treated with Chemoradiotherapy
Objectives:
Our aim was to characterize articulation proficiency and differences between tumor sites before and after chemoradiotherapy for advanced head and neck cancer with the help of acoustic measures. Our further goal was to improve objective speech measures and gain insight into muscle functioning before and after treatment.
Methods:
In 34 patients with laryngeal or hypopharyngeal, nasal or nasopharyngeal, or oral or oropharyngeal cancer, we acoustically analyzed nasality, vowel space, precision, and strength of articulation in 12 speech sounds (/α/, /i/, /u/, /p/, /s/, /z/, /l/, /t/, /tj/, /k/, /x/, /r/) before treatment and 10 weeks and 1 year after treatment. Outcomes were compared between assessment points and between tumor sites.
Results:
Nasality in nonlaryngeal sites was significantly reduced by treatment. Most affected in articulation were the oral or oropharyngeal cancer sites, followed by the nasal or nasopharyngeal sites. One year after treatment, vowel space had not recovered and consonant articulation had weakened. Laryngeal sites were less affected in articulation by tumor or treatment.
Conclusions:
Analyses of articulatory-acoustic features are a useful instrument for assessing articulation and speech quality objectively. Assessment of a number of sounds representing various articulation manners, places, and tongue shapes revealed patterns of speech deterioration after chemoradiotherapy. The results suggest that patients' speech could benefit from articulation exercises to address changes in muscle coordination and/or sensitivity and to counteract side effects and “underexercise” atrophy.

CONVERGENCIAS FENOMENOLÓGICAS Y ARTICULACIONES CONCEPTUALES ENTRE LA ACEDIA EVAGRIANA Y LA CAÍDA HEIDEGGERIANA/Phenomenological convergence and conceptual articulations between the notion of acedia in Evagrio and the notion of fall in Heidegger
Abstract In the frame of contemporary studies on the concept of acedia, and in the work of its first systematizer, the philosopher monk Evagrius Ponticus, this paper, firstly, proposes to show the many similarities between the phenomenological manifestations of acedia in Evagrius and those recognized as the \"fall\" in the Heidegger system. [...]moving into the binding capacity of such phenomenological convergences, we analyze the role of death care in the definition and configuration of both Evagrio's acedia and Heidegger's fall. La acedia, por su parte, con su marcada tendencia al vagabundeo físico, sensitivo e imaginativo es el \"principal adversario de la hesychía [^ouXaj\" (Guillaumont, Un philosophe, 200), término griego este último, intraducible al español que se vincula conceptualmente con la idea de ocio contemplativo, como bien nos indica Guillaumont (Un philosophe, 178), y que nomina, de acuerdo con Evagrio, la esencia de la vida monástica. 8También Paul Gibbs en su libro \"Heidegger's Contribution to the Understanding of Work-Based Studies\" hace una breve referencia a la noción de acedia como antecedente de que él llama la concepción moderna de aburrimiento, concepción que tendría a Heidegger como su principal artífice: \"The modern conception of boredom has an antecedent in the medieval concept of acedia, as one of the 'seven deadly sins' in the Christian tradition\" (111).

Efficacy of Electropalatography for Treating Misarticulation of /r
The purpose of the present study was to document the efficacy of electropalatography (EPG) for the treatment of rhotic errors in school-age children. Despite a growing body of literature using EPG for the treatment of speech sound errors, there is little systematic evidence about the relative efficacy of EPG for rhotic errors.
Participants were 5 English-speaking children aged 6;10 to 9;10, who produced /r/ at the word level with < 30% accuracy but otherwise showed typical speech, language, and hearing abilities. Therapy was delivered in twice-weekly 30-min sessions for 8 weeks.
Four out of 5 participants were successful in achieving perceptually and acoustically accurate /r/ productions during within-treatment trials. Two participants demonstrated generalization of /r/ productions to nontreated targets, per blinded listener ratings.
The present findings support the hypothesis that EPG can improve production accuracy in some children with rhotic errors. However, the utility of EPG is likely to remain variable across individuals. For rhotics, EPG training emphasizes one possible tongue configuration consistent with accurate rhotic production (lateral tongue contact). Although some speakers respond well to this cue, the narrow focus may limit lingual exploration of other acceptable tongue shapes known to facilitate rhotic productions.

Preschool Speech Error Patterns Predict Articulation and Phonological Awareness Outcomes in Children With Histories of Speech Sound Disorders
Purpose: To determine if speech error patterns in preschoolers with speech sound disorders (SSDs) predict articulation and phonological awareness (PA) outcomes almost 4 years later. Method: Twenty-five children with histories of preschool SSDs (and normal receptive language) were tested at an average age of 4;6 (years;months) and were followed up at age 8;3. The frequency of occurrence of preschool distortion errors, typical substitution and syllable structure errors, and atypical substitution and syllable structure errors was used to predict later speech sound production, PA, and literacy outcomes. Results: Group averages revealed below-average school-age articulation scores and low-average PA but age-appropriate reading and spelling. Preschool speech error patterns were related to school-age outcomes. Children for whom greater than 10% of their speech sound errors were atypical had lower PA and literacy scores at school age than children who produced less than 10% atypical errors. Preschoolers who produced more distortion errors were likely to have lower school-age articulation scores than preschoolers who produced fewer distortion errors. Conclusion: Different preschool speech error patterns predict different school-age clinical outcomes. Many atypical speech sound errors in preschoolers may be indicative of weak phonological representations, leading to long-term PA weaknesses. Preschoolers' distortions may be resistant to change over time, leading to persisting speech sound production problems. (Contains 4 tables, 2 figures and 1 footnote.)
