Spectral weighting functions for localization of complex sound. III. The effect of sensorineural hearing lossa).

Spectral weighting functions for sound localization were measured in participants with bilateral mild sloping to moderately severe, high-frequency sensorineural hearing loss (SNHL) and compared to normal hearing (NH) participants with and without simulated SNHL. Each participant group localized three types of complex tones, comprised of seven frequency components spatially jittered and presented from the horizontal frontal field. A threshold-elevating noise masker was implemented in the free field to simulate SNHL for participants with NH.

Multisensory Integration of Native and Nonnative Speech in Bilingual and Monolingual Adults.

Face-to-face speech communication is an audiovisual process during which the interlocuters use both the auditory speech signals as well as visual, oral articulations to understand the other. These sensory inputs are merged into a single, unified process known as multisensory integration. Audiovisual speech integration is known to be influenced by many factors, including listener experience.

The complexity of opportunities to respond used by mothers and fathers of children with Down syndrome: A preliminary investigation.

Caregiver-child interactions are commonly used to examine children's language learning environment. However, few studies consider interaction configurations beyond dyadic interactions or explore the conceptual complexity of caregiver talk. Thus, we examined if the complexity of a caregiver's opportunities to respond (OTR) varied when sampled across three interaction configurations.

Differences Between French and English in the Use of Suprasegmental Cues for the Short-Term Recall of Word Lists.

Purpose: Greater recognition of the impact of hearing loss on cognitive functions has led speech/hearing clinics to focus more on auditory memory outcomes. Typically evaluated by scoring participants' recall on a list of unrelated words after they have heard the list read out loud, this method implies pitch and timing variations across words. Here, we questioned whether these variations could impact performance differentially in one language or another.

Evidence-Based Recommendations for Tablet Recordings From the Bridge2AI-Voice Acoustic Experiments.

Background: As part of a larger goal to create best practices for voice data collection to fuel voice artificial intelligence (AI) research, the objective of this study was to investigate the ability of readily available iOS and Android tablets with and without low-cost headset microphones to produce recordings and subsequent acoustic measures of voice comparable to "research quality" instrumentation.

Methods: Recordings of 24 sustained vowel samples representing a wide range of typical and disordered voices were played via a head-and-torso model and recorded using a research quality standard microphone/preamplifier/audio interface. Acoustic measurements from the standard were compared with two popular tablets using their built-in microphones and with low-cost headset microphones at different distances from the mouth.

Radiotherapy Versus Transoral Robotic Surgery for Oropharyngeal Squamous Cell Carcinoma: Final Results of the ORATOR Randomized Trial.

Radiotherapy (RT) and transoral robotic surgery (TORS) are both curative-intent treatment options for oropharyngeal squamous cell carcinoma (OPSCC). Herein, we report the final outcomes of the ORATOR trial comparing these modalities, 5 years after enrollment completion. We randomly assigned 68 patients with T1-2N0-2 OPSCC to RT (with chemotherapy if node-positive) versus TORS plus neck dissection (± adjuvant RT/chemoradiation).

Neural response to vocal emotional intensity in youth.

Previous research has identified regions of the brain that are sensitive to emotional intensity in faces, with some evidence for developmental differences in this pattern of response. However, comparable understanding of how the brain tracks linear variations in emotional prosody is limited-especially in youth samples. The current study used novel stimuli (morphing emotional prosody from neutral to anger/happiness in linear increments) to investigate whether neural response to vocal emotion was parametrically modulated by emotional intensity and whether there were age-related changes in this effect.

Adductor Laryngeal Dystonia Versus Muscle Tension Dysphonia: Examining the Utility of Automated Acoustic Analysis to Detect Task Dependency as a Distinguishing Feature.

Objective: Differentiating adductor laryngeal dystonia (ADLD) and primary muscle tension dysphonia (pMTD) can be challenging. Unlike pMTD, ADLD is described as "task-dependent" with voiced phonemes purportedly provoking greater sign expression than voiceless phonemes. We evaluated the ability of two automated acoustic measures, the Cepstral Spectral Index of Dysphonia (CSID) and creak, to detect task dependency and to discriminate ADLD and pMTD.

Tracking dynamic social impressions from multidimensional voice representation.

Recent research by Lavan et al. explores how individuals form complex impressions from voices. Using electroencephalography and behavioral measures, the study identifies distinct time courses for discerning traits, with early acoustic processing preceding higher-order perception.

A Preliminary Examination of a Novel Telepractice Screening Protocol for Poststroke Aphasia.

Background: The delivery of telepractice interventions for people with poststroke aphasia has been found effective and feasible compared to traditional, in-person interventions; however, telepractice assessments, particularly screening protocols, which may foster convenient access to aphasia diagnostic services, have received limited examination within the aphasia literature. Therefore, the purpose of this study was to examine a novel telepractice screening protocol for people with poststroke aphasia that assesses both language and extralinguistic cognitive abilities via both performance-based and patient-reported measures.

Method: Twenty-one participants with previously diagnosed poststroke aphasia completed the telepractice administration of the Frenchay Aphasia Screening Test (FAST), the Aphasia Impact Questionnaire-21 (AIQ-21), the Oxford Cognitive Screen (OCS), and the Cognitive-Communication Checklist for Acquired Brain Injury (CCCABI).

Cross-linguistic and acoustic-driven effects on multiscale neural synchrony to stress rhythms.

We investigated how neural oscillations code the hierarchical nature of stress rhythms in speech and how stress processing varies with language experience. By measuring phase synchrony of multilevel EEG-acoustic tracking and intra-brain cross-frequency coupling, we show the encoding of stress involves different neural signatures (delta rhythms = stress foot rate; theta rhythms = syllable rate), is stronger for amplitude vs. duration stress cues, and induces nested delta-theta coherence mirroring the stress-syllable hierarchy in speech.

Considerations for identifying subtypes of speech sound disorder.

Background: Speech sound disorders (SSDs) in children are heterogeneous. Differentiating children with SSDs into distinct subtypes is important so that each child receives a treatment approach well suited to the particular difficulties they are experiencing.

Aims: To study the distinct underlying processes that differentiate phonological processing, phonological planning or motor planning deficits.

The child the apple eats: processing of argument structure in Mandarin verb-final sentences.

Mandarin Chinese is typologically unusual among the world's languages in having flexible word order despite a near absence of inflectional morphology. These features of Mandarin challenge conventional linguistic notions such as subject and object and the divide between syntax and semantics. In the present study, we tested monolingual processing of argument structure in Mandarin verb-final sentences, where word order alone is not a reliable cue.

Individual differences in the consistency of neural and behavioural responses to speech sounds.

There are documented individual differences among adults in the consistency of speech sound processing, both at neural and behavioural levels. Some adults show more consistent neural responses to speech sounds than others, as measured by an event-related potential called the frequency-following response (FFR); similarly, some adults show more consistent behavioural responses to native speech sounds than others, as measured by two-alternative forced choice (2AFC) and visual analog scaling (VAS) tasks. Adults also differ in how successfully they can perceive non-native speech sounds.

A Role for Health Literacy in Protecting People With Limited English Proficiency Against Falling: A Retrospective, Cohort Study.

Objective: To identify risk factors related to falls within the scope of speech-language pathology (SLP) using assessments from the Inpatient Rehabilitation Facility-Patient Assessment Instrument over a 4-month period in 4 inpatient rehabilitation facilities (IRFs).

Design: Observational retrospective cohort study.

Setting: Four IRFs as part of a larger learning health system.

Trends in Injectable Biomaterials for Vocal Fold Regeneration and Long-Term Augmentation.

Human vocal folds (VFs), a pair of small, soft tissues in the larynx, have a layered mucosal structure with unique mechanical strength to support high-level tissue deformation by phonation. Severe pathological changes to VF have causes including surgery, trauma, age-related atrophy, and radiation, and lead to partial or complete communication loss and difficulty in breathing and swallowing. VF glottal insufficiency requires injectable VF biomaterials such as hyaluronan, calcium hydroxyapatite, and autologous fat to augment VF functions.

Perceptual compensation for vowel intrinsic f0 effects in native English speakers.

High vowels have higher f0 than low vowels, creating a context effect on the interpretation of f0. Since onset F0 is a cue to stop voicing, the vowel context is expected to influence voicing judgements. Listeners categorized syllables starting with high ("bee"-"pea") and low ("bye"-"pie") vowels varying orthogonally in VOT and onset F0.

Making Assessment Real: Audrey Holland's Contributions to the Assessment of Aphasia and Cognitive-Communication Disorders in Clinical and Research Settings.

For half a century, Dr. Audrey Holland investigated, developed, and implemented ways to extend the assessment of adult language and cognitive-communication disorders beyond traditional impairment-based approaches. This article summarizes Dr.

Telepractice Assessments for Individuals with Aphasia: A Systematic Review.

Current literature broadly demonstrates the effectiveness and feasibility of telepractice services for people with aphasia. However, the examination of telepractice assessments for people with aphasia is limited. The purpose of this systematic review was to examine the current use of telepractice assessment protocols for people with aphasia.

Perceptual awareness of near-threshold tones scales gradually with auditory cortex activity and pupil dilation.

Negative-going responses in sensory cortex co-vary with perceptual awareness of sensory stimuli. Given that this awareness negativity has also been observed for undetected stimuli, some have challenged its role for perception. To address this question, we combined magnetoencephalography, electroencephalography, and pupillometry to study how sustained attention and response criterion affect the auditory awareness negativity.

Single-cell RNA-Seq reveals the heterogeneity of fibroblasts within the tympanojugular paraganglioma microenvironment.

Tympanojugular paragangliomas (TJP) originate from the parasympathetic ganglia in the lateral base of the skull. Although the cellular composition and oncogenic mechanisms of paragangliomas have been evaluated, a comprehensive transcriptomic atlas specific to TJP remains to be established to facilitate further investigations. In this study, single-cell RNA sequencing and whole-exome sequencing were conducted on six surgically excised TJP samples to determine their cellular composition and intratumoral heterogeneity.
