Infant Behavioral Speech Discrimination Procedures: A Systematic Review
… of literature relating to two behavioral infant speech discrimination procedures to evaluate their potential clinical utility. The two procedures examined were the Observer-based Psychoacoustic Procedure (OPP) and the Visual Reinforcement of Infant Speech Discrimination (VRISD) method. The …

Maturation of Speech Discrimination and Attentional Requirements in Late Childhood
<p>The ability to perceive speech sounds and contrasts continues to be refined throughout the course of development. While emerging models suggest that development is characterized by shifts from an attentionally demanding mode of processing speech sounds to one that occurs relatively …

The effects of hearing protection on speech discrimination in differing noise spectra
… research project was aimed at investigation of speech communication issues in industrial noise environments where workers utilize hearing protection devices (HPDs). A controlled empirical study was conducted to determine the effects of several independent variables on speech reception and …

Sensorimotor Modulations by Cognitive Processes During Accurate Speech Discrimination: An EEG Investigation of Dorsal Stream Processing
… regions of the dorsal stream in support of speech perception, though it remains unclear how this mechanism responds to cognitive processes in service of task demands. The purpose of the current study was to identify the influences of attention and working memory on sensorimotor activity …

Independent Component Analysis of Event-Related Electroencephalography During Speech and Non-Speech Discrimination: : Implications for the Sensorimotor ∆∞ Rhythm in Speech Processing
… of sensorimotor integration in acoustic speech processing is unclear despite more than three decades of neuroimaging research. Constructivist theories have long speculated that listeners make predictions about articulatory goals functioning to weight sensory analysis toward expected …

Performance Intensity Functions for Digitally Recorded Japanese Speech Audiometry Materials
… of this study was to develop digitally recorded speech audiometry materials in the Japanese language to evaluate Speech Reception Threshold (SRT) and speech discrimination. Trisyllabic words were used to evaluate the SRT and bisyllabic words were used for speech discrimination. Words were …

Psychometrically Equivalent Digital Recordings for Speech Audiometry Testing in Mandarin Chinese: Standard Mandarin Dialect
The development of digitally recorded speech audiometry materials in Mandarin Chinese has been limited to date. High quality materials proliferate in the English language and have been developed for other languages such as Brazilian Portuguese, Spanish, Japanese, Korean, French, Italian, Polish, …

Psychological implications of acquired deafness for adults of employment age
… session pure tone audiometry and a test of speech discrimination was carried out; a number of other audio-logical variables were also quantified. An inventory designed to identify the psychologically disturbed, with norms for the general and psychiatric populations, was administered. A …

Computer assisted audiometric evaluation system
… personal computer to perform pure tone and speech tests and · comprises a plug-in card and custom software. The card contains pure tone and masking noise generators, together with amplifiers for a. set of headphones .and bone conduction transducer, patient and audiologist microphone …

Do Infants Discriminate Hyper-from Non-Hyperarticulated Speech?
… articulation when engaging in infant directed speech (IDS) can result in "clear speech" by the expansion of the vowel space area. The degree of speech clarity produced by caregivers appears to provide advantages for young language learners to promote lexical perception and learning. However few …

Automatic Activation of Phonological Templates for Native but Not Nonnative Phonemes: An Investigation of the Temporal Dynamics of Mu Activation
<p>Models of speech perception suggest a dorsal stream connecting the temporal and inferior parietal lobe with the inferior frontal gyrus. This stream is thought to involve an auditory-motor loop that translates acoustic information into motor/articulatory commands and is further influenced by …

Sublexical, lexical and phonological short-term memory processes: Evaluating models of speech perception and short-term memory
… research examined the processes involved in speech perception and the relation of speech perception to phonological short-term memory (pSTM). Contrary to traditional models which assume that sublexical processing necessarily precedes lexical processing (e.g., McClelland & Elman, 1986; Norris, …

Cochlear neuropathy : detection using envelope following responses and Impacts on central auditory coding
… in listeners with normal audiograms, such as speech discrimination in noise and ability to use envelope cues. We searched for neural correlates of these deficits in the mouse auditory midbrain following exposure. Consistent with reductions in EFRs, synchronization to envelopes was impaired. …

The Effect of Cochlear Dysfunction on Central Auditory Speech Test Performance
… of cochlear dysfunction on central auditory speech test performance. There has been limited research reported concerning the effects of peripheral hearing loss occurring in the absence of central auditory pathology on tests specifically designed to diagnose central auditory impairment. …

Psychometrically Equivalent Trisyllabic Words for Speech Reception Threshold Testing in Cantonese
… could then be used in the measurement of the speech reception threshold. A selection of 90 frequently utilized trisyllabic words were selected and then digitally recorded by male and female talkers of Standard Cantonese and presented to 20 subjects with normal hearing beginning at 6 dB below …
