“…Computer applications in geography snippet". These were selected in the experimental design described in [87] since the first contains poetic structures and the second contains technical jargon, both of which are less familiar to participants' everyday text. In the second set of recordings, the participants start a spontaneous dialogue with the test executor, who asks random questions.…”

Ataxic speech disorders and Parkinson’s disease diagnostics via stochastic embedding of empirical mode decomposition

Medical diagnostic methods that utilise modalities of patient symptoms such as speech are increasingly being used for initial diagnostic purposes and monitoring disease state progression. Speech disorders are particularly prevalent in neurological degenerative diseases such as Parkinson’s disease, the focus of the study undertaken in this work. We will demonstrate state-of-the-art statistical time-series methods that combine elements of statistical time series modelling and signal processing with modern machine learning methods based on Gaussian process models to develop methods to accurately detect a core symptom of speech disorder in individuals who have Parkinson’s disease. We will show that the proposed methods out-perform standard best practices of speech diagnostics in detecting ataxic speech disorders, and we will focus the study, particularly on a detailed analysis of a well regarded Parkinson’s data speech study publicly available making all our results reproducible. The methodology developed is based on a specialised technique not widely adopted in medical statistics that found great success in other domains such as signal processing, seismology, speech analysis and ecology. In this work, we will present this method from a statistical perspective and generalise it to a stochastic model, which will be used to design a test for speech disorders when applied to speech time series signals. As such, this work is making contributions both of a practical and statistical methodological nature.

“…Many eminent researchers 3,4,5 have proposed modifications to the Sabine relationship, and Standards have been developed 6 , in an attempt to calculate the reverberation time in rooms with uneven distribution of absorption, in more highly damped rooms, or in larger rooms intended as performance spaces 7 . Similarly, parameters to describe the degree of non-linearity of a decay curve have been proposed.…”

Reverberation time remains the primary indicator of room acoustic response. However, previous work has shown that reverberation time alone can be insufficient to describe the acoustic conditions, particularly in non-diffuse environments such as classrooms where the majority of absorption is typically on one surface.Alternative parameters have been proposed to evaluate the acoustic response of such rooms: Strength, G, and Speech Clarity, C 50 . These correlate better with loudness and speech intelligibility, in the absence of background noise. This paper investigates the practical use of G and C 50 to describe the acoustic response of classrooms. Measurements and modelling are used to investigate the spatial variation with frequency, source position, measurement distance, and room size. Correlation between modelled and measured values is investigated.Guidance on source and receiver positions is proposed to achieve consistent results, so that the results may describe the room rather than one particular measurement set up.

“…Many researchers have proposed modifications to the Sabine or Eyring relations to try and predict reverberation time in spaces where there is an uneven distribution of absorption, such as Fitzroy [2], Arau-Puchades [3], and Nilsson in Annexe D of BS EN 12354-6 [4]. However, in these circumstances, it is less likely that the reverberation time will relate to other acoustic parameters which may be better correlated with the users requirements, such as limiting the build-up of reverberant sound or speech intelligibility.…”
