What diagnostic protocols are being used for auditory processing disorder?5 answersVarious diagnostic protocols are utilized for auditory processing disorder (APD). These protocols include a combination of speech and non-speech tests with pass-fail cut-off criteria consistent with diagnosing co-morbidities. Clinical measures such as the duration pattern test (DPT), frequency pattern test (FPT), and gaps-in-noise (GIN) test have shown effectiveness in diagnosing APD in adults with neurological disorders. A multi-disciplinary assessment protocol in French language involves speech tests, psychometric assessments, ENT examinations, and auditory attention tests to diagnose APD in children suspected of the disorder. Neuroimaging techniques like MRI, MEG, and PET are recommended for diagnosing APD by identifying abnormal brain activity in children with CAPD, although behavioral tests remain the primary diagnostic method. Current test batteries in audiology combine clinical observation, behavioral assessments, electrophysiological assessments, and speech-language assessments to diagnose APD, but there is a need for improved techniques to differentiate APD from other developmental delays.
What are the current testing batteries used for AUditory processing disorder?5 answersCurrently, various testing batteries are utilized for Auditory Processing Disorder (APD) assessment. The existing behavioral test batteries for APD diagnosis face controversies due to comorbidity issues and lack of domain specificity. To address this, a proposed solution involves implementing an objective, physiological test battery for more specific auditory domain assessment. Additionally, a new battery named BAPA-PE for Central Auditory Processing assessment in European Portuguese children has been developed, consisting of six behavioral tests with normative data available. Another study suggests a hierarchical approach to APD assessment, starting with an overall test of listening difficulty and progressing to master and detailed test batteries for specific APD diagnosis. Evaluations of pre-packaged behavioral test batteries like SCAN and MAPA indicate that while SCAN alone may not be sufficient, the MAPA battery shows promise for APD assessment in children.
How to measure speech intelligibility?4 answersSpeech intelligibility can be measured using various methods. One common approach is to use intelligibility measures, which assess the number of words or phonemes a listener correctly transcribes or repeats. Another method involves developing deep neural networks that estimate a standardized intelligibility score based on acoustic input. Additionally, speech transmission index (STI) can be used to provide a quantitative measure of speech intelligibility through personal protective facemasks. Another method involves comparing time-dependent signals derived from auditory stimuli with corresponding measured EEG responses to determine a measure of speech intelligibility. Furthermore, a modified version of the speech transmission index called broadband STI (bSTI) has been proposed for assessing the performance of nonlinear speech intelligibility enhancement methods.
How to measure listening ?4 answersListening can be measured using subjective tools, electrophysiologic measures, or a dual-task paradigm. Subjective tools include self-reports and questionnaires, which allow individuals to report their own perception of their listening effort. Electrophysiologic measures involve measuring physiological responses such as pupil dilation, heart rate variability, and skin conductance, which can indicate the level of mental exertion required for listening. A dual-task paradigm involves performing two tasks simultaneously, with the decline in performance on the secondary task indicating the amount of effort exerted on the primary listening task. These methods have their strengths and limitations, and ongoing research is exploring their effectiveness in measuring listening effort. Additionally, models of listening effort related to speech recognition have been developed, aiming to understand the needs of hearing impaired individuals and support the development of signal processing algorithms in hearing aids to decrease listening effort.
What are the different methods used by neurofeedback devices to measure brain activity?5 answersNeurofeedback devices use different methods to measure brain activity. One method involves using EEG sensors positioned across the scalp to collect EEG data. These sensors are constructed with absorbent portions that can be moistened with conductive fluid and held in place using adjustable flexible bands. Another method involves using source-based signal processing methods in EEG neurofeedback. This method targets the desired physiological signal in a more functionally and spatially specific manner by utilizing Blind Source Separation (BSS) of EEG data. Additionally, transcranial brain stimulation approaches such as repetitive transcranial magnetic stimulation (rTMS) and transcranial alternating current stimulation (tACS) have been used to modulate brain oscillations and assess causal relationships between brain oscillations and cognition. Furthermore, a brain activity training apparatus calculates the correlation of connectivity between brain areas using signals detected from a trainee during resting and self-regulation periods, and presents feedback information based on the calculated information.
How to measure speech rate?5 answersSpeech rate can be measured in various ways. One common approach is to count the number of linguistic units, such as words, syllables, or phones, that occur within a given time period. Phone-based rate measures tend to have stronger correlations with segment durations than other measures. It is also important to consider the size and location of the window used to count units, as well as whether the measure is expressed as an event rate or its reciprocal. Another method involves using automatic detection of syllable nuclei to measure speech rate without the need for transcription. Additionally, a novel method uses patterns of speech-sound sequences to estimate speech rate, based on the durations of similar patterns. Rhythmicity features derived from the short-time energy envelope can also be used to estimate speech rate.
