In the last few years, archaeoacoustic studies of rock art sites and landscapes have undergone significant growth as a result renewed interest in intangible aspects archaeological record. This article focuses on acoustic study carried out complex Bacinete, Cádiz (Spain). After describing site its importance, representative set monaural spatial IRs gathered onsite is thoroughly analysed to explo...

Modeling phonological units of speech is a critical issue in speech recognition. In this paper, we report our recent development of an overlapping-feature based phonological model which represents long-span contextual dependency in speech acoustics. In this model, high-level linguistic constraints are incorporated in automatic construction of the feature overlapping patterns and the associated ...

An earlier study compared audiovisual perception of speech ’produced in environmental noise’ (Lombard speech) and speech ’produced in quiet’ with the same environmental noise added. The results and showed that listeners make differential use of the visual information depending on the recording condition, but gave no indication of how or why this might be so. A possible confound in that study wa...

Many educational institutions include a course on speech processing as part of their regular curriculum. Such courses usually cover basic principles in acoustics, phonetics and speech signal processing, and they often incorporate practical lab classes using specialised speech processing toolboxes such as ‘Praat’. Such toolkits are valuable resources for teaching and learning, but they often inv...

We discuss post-processing of speech that has been recorded during Magnetic Resonance Imaging (MRI) of the vocal tract area. These speech recordings are contaminated by high levels of acoustic noise from the MRI scanner. Also, the frequency response of the sound signal path is not flat as a result of restrictions on recording instrumentation and arrangements due to MRI technology. The post-proc...

Bayesian Networks are a particular type of Graphical Models, providing a general and flexible framework to model, factor, and compute joint probability distributions among random variables in a compact and efficient way. For speech recognition, a BN permits each speech frame to be associated with an arbitrary set of random variables. They can be used to augment well-known statistical paradigms ...

Spectral degradation reduces access to the acoustics of spoken language and compromises how learners break into its structure. We hypothesised that spectral degradation disrupts word segmentation, but that listeners can exploit other cues to restore detection of words. Normalhearing adults were familiarised to artificial speech that was unprocessed or spectrally degraded by noise-band vocoding ...

Stance-taking, the expression of opinions or attitudes, informs the process of negotiation, argumentation, and decisionmaking. While receiving significant attention in text materials in work on the related areas of subjectivity and sentiment analysis, the expression of stance in speech remains less explored. Prior analysis of the acoustics of stance-expression in conversational speech has ident...

Acoustical properties of speech have been shown to be related to mental states of speaker with symptoms: depression and remission. This paper describes way to address the issue of distinguishing depressed patients from remitted subjects based on measureable acoustics change of their spoken sound. The vocal-tract related frequency characteristics of speech samples from female remitted and depres...

This study looks at how the conflicting goals of chewing and speech production are reconciled by examining the acoustic and articulatory output of talking while chewing. We consider chewing to be a type of perturbation with regard to speech production, but with some important differences. Ultrasound and acoustic measurements were made while participants chewed gum and produced various utterance...
