Ashraf Alkhairy, Afshan Jafri
Heterophones pose challenges during training of automatic speech recognition (ASR) systems because they involve ambiguity in the pronunciation of an orthographic representation of a word. Heterophones are words that have the same spelling but different pronunciations. This paper addresses the problem of heterophonic languages by developing the concept of a Composite Phoneme (CP) as a basic pronunciation unit for speech recognition. A CP is a set of alternative sequences of phonemes. CP's are developed specifically in the context of Arabic by defining phonetic units that are consonant centric and absorb phonemically contrastive short vowels and gemination, not represented in the Arabic Modern Orthography (MO)...

Objectives: Patients with bilateral vocal fold paralysis (BVFP) theoretically have difficulty producing voiceless consonants. However, perceptual studies have revealed clear production of voiceless consonants with good articulation scores in nontracheostomized patients. The purpose of this study was to clarify the production of voiceless stops during articulation in patients with BVFP compared to normal speakers. Methods: The perceptual, acoustic, and aerodynamic characteristics of patients with BVFP and those with normal speech were investigated with special reference to voiceless stop consonants...

OBJECTIVES: This study investigates whether a change in speaking voice focus affects the oral-nasal balance. The investigation was undertaken with different phonetic materials in speakers of Brazilian Portuguese, which features phonological and phonetic vowel nasalization. METHODS: Ten females read oral, balanced oral-nasal, and nasal loaded sentences in their normal voice, and with a backward focus and a forward focus. Nasalance scores were collected with a Nasometer 6400...

Musical training modifies neural areas associated with both music and language and enhances speech perception and discrimination by engaging the right hemisphere regions classically associated with music processing. On these bases we hypothesized that participants with extended musical training could have reduced left-hemisphere dominance for speech. In order to verify this hypothesis, two groups of right-handed individuals, one with long-term musical training and one with no musical training, participated to a Dichotic Fused Word Test consisting in the simultaneous presentation of different pairs of rhyming words and pseudo-words, one to the left ear and one to the right one...

Studies on perceptual learning are motivated by phonetic variation that listeners encounter across speakers, items, and context. In this study, the authors investigate what control the listener has over the perceptual learning of ambiguous /s/ pronunciations through inducing changes in their attentional set. Listeners' attention is manipulated during a lexical decision exposure task such that their attention is directed at the word-level for comprehension-oriented listening or toward the signal for perception-oriented listening...

Speech perception abilities vary substantially across listeners, particularly in adverse conditions including those stemming from environmental degradation (e.g., noise) or from talker-related challenges (e.g., nonnative or disordered speech). This study examined adult listeners' recognition of words in phrases produced by six talkers representing three speech varieties: a nonnative accent (Spanish-accented English), a regional dialect (Irish English), and a disordered variety (ataxic dysarthria). Semantically anomalous phrases from these talkers were presented in a transcription task and intelligibility scores, percent words correct, were compared across the three speech varieties...

This study investigates the spontaneous phonetic imitation of coarticulatory vowel nasalization. Speakers produced monosyllabic words with a vowel-nasal sequence either from dense or sparse phonological neighborhoods in shadowing and word-naming tasks. During shadowing, they were exposed to target words that were modified to have either an artificially increased or decreased degree of coarticulatory vowel nasality. Increased nasality, which is communicatively more facilitative in that it provides robust predictive information about the upcoming nasal segment, was imitated more strongly during shadowing than decreased nasality...

The speech stream simultaneously carries information about talker identity and linguistic content, and the same acoustic property (e.g., voice-onset-time, or VOT) may be used for both purposes. Separable neural networks for processing talker identity and phonetic content have been identified, but it is unclear how a singular acoustic property is parsed by the neural system for talker identification versus phonetic processing. In the current study, listeners were exposed to two talkers with characteristically different VOTs...

The aim of our study was to present success and complication rates of 32 zygomatic implants (ZI) and compare satisfaction of patients rehabilitated with ZI supported hybrid prosthesis in atrophic jaws and removable prosthesis in maxillary defects. Sixteen patients who have been diagnosed as atrophic maxilla or maxillary defect were treated with ZI supported hybrid or removable prosthesis between 2008 and 2016 years, respectively. Thirty-two of 70 implants were placed in the zygomatic bone. Two prosthetic groups were compared 1 month after prosthesis delivery in terms of general satisfaction, stability, performance, esthetics, phonetics, hygiene level based on visual analog scale...

BACKGROUND: A pattern of ingressive substitutions for word-final sibilants can be identified in a small number of cases in child speech disorder, with growing evidence suggesting it is a phonological difficulty, despite the unusual surface form. Phonological difficulty implies a problem with the cognitive process of organizing speech into sound contrasts. AIMS: To evaluate phonological therapy approaches in the remediation of non-pulmonic speech errors. Thus, adding to evidence concerning the nature of ingressive substitutions and their remediation whilst highlighting their occurrence within child speech disorder population for practising and training speech and language therapists...

PURPOSE: The aim of this study was to explore cluster acquisition in typically developing German-speaking 2-year-olds. METHOD: Data from four cross-sectional studies (n = 145, aged 2;00-2;11) and one eight-month longitudinal study were analysed (n = 6, aged 2;01-2;04). Two different percentages of consonant clusters correct were calculated to allow a more detailed analysis. RESULT: Findings showed that the majority of children produced clusters, although they could not be considered to be fully acquired...

This study aimed to (a) explore the roles of cognitive and language variables in predicting reading abilities of two groups of individuals with reading disabilities (i.e., dyslexia and specific language impairment) and (b) examine which variable(s) is the most predictive in differentiating two groups. Inclusion/exclusion criteria applied to categorize the two groups yielded a total of 63 participants (n = 44 for the dyslexia; n = 19 for the specific language impairment). A stepwise multiple regression approach was conducted to examine which cognitive and/or language variables made the largest contribution to reading abilities (i...

This study investigated the relation between lexical development and the production of prosodic prominence in disyllabic babble and words. Monthly recordings from nine typically developing Belgian-Dutch-speaking infants were analyzed from the onset of babbling until a cumulative vocabulary of 200 words was reached. The differentiation between the two syllables of isolated disyllabic utterances was computed for f0, intensity, and duration measurements. Results showed that the ambient trochaic pattern emerged in babble, but became enhanced in words...

: Esthetics is a prime concern for a young lady. Any anomaly in the anterior tooth may create anxiety and depression. This anxiety and depression may hamper her married life and overall personality. This case report reveals an unerupted right central incisor situated in a strange position, creating space in the maxillary anterior region and giving an unesthetic appearance. Autotransplantation is a method of choice for a strangely positioned impacted central incisor in a new appropriate site...

Sublexical phonotactic regularities in language have a major impact on language development, as well as on speech processing and production throughout the entire lifespan. To understand the impact of phonotactic regularities on speech and language functions at the behavioral and neural levels, it is essential to have access to oral language corpora to study these complex phenomena in different languages. Yet, probably because of their complexity, oral language corpora remain less common than written language corpora...

Asterios Toutios, Shrikanth S Narayanan
Real-time magnetic resonance imaging (rtMRI) of the moving vocal tract during running speech production is an important emerging tool for speech production research providing dynamic information of a speaker's upper airway from the entire mid-sagittal plane or any other scan plane of interest. There have been several advances in the development of speech rtMRI and corresponding analysis tools, and their application to domains such as phonetics and phonological theory, articulatory modeling, and speaker characterization...

This study consolidates findings on phonetic convergence in a large-scale examination of the impacts of talker sex, word frequency, and model talkers on multiple measures of convergence. A survey of nearly three dozen published reports revealed that most shadowing studies used very few model talkers and did not assess whether phonetic convergence varied across same- and mixed-sex pairings. Furthermore, some studies have reported effects of talker sex or word frequency on phonetic convergence, but others have failed to replicate these effects or have reported opposing patterns...

Xin Xie, Rachel M Theodore, Emily B Myers
The literature on perceptual learning for speech shows that listeners use lexical information to disambiguate phonetically ambiguous speech sounds and that they maintain this new mapping for later recognition of ambiguous sounds for a given talker. Evidence for this kind of perceptual reorganization has focused on phonetic category boundary shifts. Here, we asked whether listeners adjust both category boundaries and internal category structure in rapid adaptation to foreign accents. We investigated the perceptual learning of Mandarin-accented productions of word-final voiced stops in English...

This study explored the effects on speech intelligibility of across-formant differences in fundamental frequency (ΔF0) and F0 contour. Sentence-length speech analogues were presented dichotically (left=F1+F3; right=F2), either alone or-because competition usually reveals grouping cues most clearly-accompanied in the left ear by a competitor for F2 (F2C) that listeners must reject to optimize recognition. F2C was created by inverting the F2 frequency contour. In experiment 1, all left-ear formants shared the same constant F0 and ΔF0F2 was 0 or ±4 semitones...

The article describes the medical and dental procedures for four treatment sessions with the Digital Denture Professional (DDP) system. First, conventional preliminary dental impressions of the full arch are taken to achieve accurate jaw positioning records. The study models and patient data are digitalised using a laboratory scanner. The dental lab technician then constructs and mills custom impression trays and a mount as an intraoral instrument. A closed-mouth impression is then taken to record vertical dimensions and central relation position...
