Altered Auditory Feedback Improves Speech Intelligibility in Individuals Diagnosed with Parkinson's Disease: A Pilot Study.

Introduction: The purpose of the current study was to evaluate speech intelligibility and speech rate in individuals with Parkinson's disease using altered auditory feedback (AAF) in comparison to age-matched healthy controls. Based on prior research, it is hypothesized that the use of AAF will improve participants' speech intelligibility.

Methods: Five individuals with Parkinson's disease (clinical group) and five age-matched healthy controls aged 50 years and above participated in this pre-/post-group experiment.

The role of lag effect in distributed practice on learning novel vocabulary.

Purpose: The purpose of the current study was to investigate the lag effects in two different versions of distributed practice on learning novel language vocabulary.

Method: Forty-four healthy monolingual English-speaking participants were randomly assigned to two versions of distributed practice. The two versions of distributed practice were created by altering the temporal lag between the practice sessions.

Role of Massed Versus Distributed Practice in Learning Novel Foreign Language Utterances.

The current study compared the role of massed versus distributed practice in learning novel foreign language utterances. Fifty healthy native English-speaking participants were randomly assigned to either massed or distributed practice groups. All participants practiced eight novel French utterances 25 times each for a total of 200 times, with the spacing of practice sessions differing between the two groups.

Speech, language, and hearing function in twins with Alport syndrome: A seven-year retrospective case report.

Alport syndrome is an X-linked syndrome that results in nephritis, renal failure, sensorineural hearing loss, and eye deficits. As a result of sensorineural hearing loss, these individuals are likely to experience difficulties in the area of speech and language. While studies in the past have examined the speech and language characteristics of children with syndromic sensorineural hearing loss, to our knowledge there are no previous studies to have documented the speech and language characteristics of these children on a long-term basis.

Role of Constant, Random and Blocked Practice in an Electromyography-Based Oral Motor Learning Task.

Purpose: The role of principles of motor learning (PMLs) in speech has received much attention in the past decade. Oral motor learning, however, has not received similar consideration. This study evaluated the role of three practice conditions in an oral motor tracking task.

Is There an Interaction between Task Complexity and Practice Variability in Speech-Motor learning?

Background: Prior studies have investigated the influence of principles of motor learning (PMLs) on speech-motor learning. However, the interactive effect of different PMLs on speech-motor learning remains unknown.

Purpose: This study is aimed at investigating the interaction of 2 PMLs, that is, practice variability and task complexity and their influence on speech-motor learning.

Functioning of medial olivocochlear bundle in right- and left-handed individuals.

Functional symmetry of medial olivocochlear bundle (MOCB) as a function of handedness remains to be well investigated. The current study aimed to assess the functional symmetry of MOCB through contralateral inhibition of otoacoustic emissions (OAEs) in right- and left-handed individuals. Thirteen left-handed and 13 right-handed individuals in the age range of 19-25 years participated.

Efficacy of auditory-verbal therapy in children with hearing impairment: A systematic review from 1993 to 2015.

Objectives: Auditory verbal therapy (AVT) is one of the primary treatment approaches for developing spoken language in children with hearing impairment (HI), but its outcomes have not been thoroughly investigated. The current study aimed to systematically review past studies investigating AVT outcomes in children with HI.

Methods: A systematic search was conducted in six databases.

Are individuals with Parkinson's disease capable of speech-motor learning? - A preliminary evaluation.

Introduction: The benefits of different practice conditions in limb-based rehabilitation of motor disorders are well documented. Conversely, the role of practice structure in the treatment of motor-based speech disorders has only been minimally investigated. Considering this limitation, the current study aimed to investigate the effectiveness of selected practice conditions in spatial and temporal learning of novel speech utterances in individuals with Parkinson's disease (PD).

A systematic review of treatment intensity in speech disorders.

Purpose: Treatment intensity (sometimes referred to as "practice amount") has been well-investigated in learning non-speech tasks, but its role in treating speech disorders has not been largely analysed. This study reviewed the literature regarding treatment intensity in speech disorders.

Method: A systematic search was conducted in four databases using appropriate search terms.

Auditory interference control in children with learning disability: An exploratory study.

Objectives: The current study aimed to compare the auditory interference control of participants with Learning Disability (LD) to a control group on two versions of an auditory Stroop task.

Methods: A group of eight children with LD (clinical group) and another group of eight typically developing children (control group) served as participants. All the participants were involved in a semantic and a gender identification-based auditory Stroop task.

The use of non-speech oral-motor exercises among Indian speech-language pathologists to treat speech disorders: An online survey.

Objective: Previous surveys in the United States of America (USA), the United Kingdom (UK), and Canada have indicated that most of the speech-language pathologists (SLPs) tend to use non-speech oral-motor exercises (NSOMEs) on a regular basis to treat speech disorders.At present, there is considerable debate regarding the clinical effectiveness of NSOMEs. The current study aimed to investigate the pattern and extent of usage of NSOMEs among Indian SLPs.

Brief report: an unusual manifestation of diagnostic overshadowing of pervasive developmental disorder--not otherwise specified: a five year longitudinal case study.

Children with communication disorders present with a range of comorbid conditions. Occasionally one of the comorbid conditions manifests so strongly that the primary condition goes unnoticed by the clinician. This tendency to overlook comorbid health problems in the presence of a disability is referred to as diagnostic overshadowing.

Recovery of speech following total glossectomy: an acoustic and perceptual appraisal.

This study involved an acoustic and perceptual analysis of the speech produced by a 31-year-old female following total glossectomy. Speech samples were collected on three occasions within the first 3 months following glossectomy. Vowel articulation was examined acoustically as a function of vowel space and the Euclidean distance separating corner vowels.

Acoustic estimates of respiration in the pain cries of newborns.

Objective: The purpose of the present study was to examine the temporal features of pain-elicited crying demonstrated by healthy full term infants to estimate (1) the respiratory rate during cry and (2) the inspiratory and expiratory phase composition of the cry respiratory cycle.

Patients And Methods: The pain-elicited cries of 12 newborn infants were recorded within the first 2 weeks following birth. A complete crying episode was analyzed for each infant and acoustically measured for the number and duration of inspiratory and expiratory cry components.
