In this article we will explore the consequences of adopting recent proposals by Chomsky, according to which the syntactic derivation proceeds in terms of phases. The notion of phase – through the associated notion of spellout – allows for an insightful theory of the fact that syntactic constituents receive default phrase stress not across the board, but as(More)
Depression is a severe mental health disorder with high societal costs. Current clinical practice depends almost exclusively on self-report and clinical opinion, risking a range of subjective biases. The long-term goal of our research is to develop assistive technologies to support clinicians and sufferers in the diagnosis and monitoring of treatment(More)
This paper argues that generalizations about prosodic phrasing are recursive in nature. Initial evidence comes from the fragment of English consisting only of proper names and and and or. A systematic relation between the semantics, the syntactic combi-natorics, and the prosodic phrasing of these coordinate structures can be captured by recursively(More)

Acoustic correlates of information structure 2 Abstract This paper reports three studies aimed at addressing three questions about the acoustic correlates of information structure in English: (1) do speakers mark information structure(More)
Speaker identification experiments are performed with novel features representative of the glottal source waveform. These are derived from closed-phase analysis and inverse filtering. Source waveforms are segmented into two consecutive periods and normalised in prosody, forming so called source-frame feature vectors. Support-vector-machines are used to(More)
Vector Quantisation (VQ) has been shown to be robust in speaker recognition systems which require a small amount of training data. However the conventional VQ-based method only uses distortion measurements and discards the sequence of quantised codewords. In this paper we propose a method which extends the VQ distortion method by combining it with the(More)
RÉSUMÉ Dans la reconnaisance du locuteur, la regle du maximum de vraisemblance (ML) est utilise comme critere pour affecter une sequence donnee de vecteurs acoustiques au modele maximum de vraisemblance du locuteur. Parcontre cette regle n'est pas toujours applicable dans certains cas. Une autre regle de decision, moyenne normalisee maximum de vraisemblance(More)
Previous research found that the relative rather than absolute size of prosodic boundaries is crucial in disambiguating attachment ambiguities [1, 2]. Furthermore, relative categorical differences matter whereas merely quantitative ones do not [1]. This paper presents further evidence that relative boundary strength is indeed crucial, but, contrary to(More)
The glottal volume-velocity (voice-source) waveform, describing the airflow from the lungs shaped by the vibratory motion of the speakers' vocal folds and input to the vocal tract during the speech production process, has been shown to contain speaker discriminatory information (Vandyke, 2012 & references therewith). Despite there having been various(More)
