    Boundary disputes and sociophonetic variation: schwa-epenthesis in Dutch rCclusters

    No full text
    Dutch schwa-epenthesis in liquid+consonant clusters has been the subject of a “boundary dispute”, as to its phonetic or phonological status. There has been surprisingly little instrumental work on the phenomenon that could function as an arbiter in this dispute. This paper attempts to remedy this situation by bringing results from a corpus of sociophonetic variation data to bear on the issue, focussing on the duration of the epenthesised schwa and variability of /r/ in rC clusters. The results show that both phonetic and phonological factors may be at play, and that there are intricate patterns of dialectal variation, highlighting the relevance of sociophonetic data on phonetics-phonology interface issues

    Fa-fa-fa-fa, de doo doo doo, de da da da, sha la la la lee:What is the optimal syllable in improvised singing?

    No full text
    The aim of this paper is to describe and account for the optimal syllable structure in improvised singing without lyrics. Improvised singing has an overall relaxed character and it is abstracted from meaning. Furthermore, singing in general involves an exaggerated articulation of speech sounds. Unmarked syllable structures with maximal contrasts are therefore expected in improvised singing. In this paper we report on an experiment in which musicians improvise on three melodies. The results show that the optimal syllable depends on the interaction of three influences: maximal contrast between constriction and release, accuracy and rate of the muscles of the relevant articulators and maintenance of voicing. The difference betweenoptimal syllables in speech and singing can be found in differences in the weight of these influences. The syllable /da/ turns out to have the preferred syllable structure in improvised singing

    Correction After publication of the article [1], it has been brought to our attention that the first and last names of the third author were transposed in the original article. The author was published as “Ponnet Koen” where in fact the correct name is “Koen Ponnet”. The original article has been revised to reflect this

    Acceptance conditions in automated negotiation

    No full text
    In every negotiation with a deadline, one of the negotiating parties has to accept an offer to avoid a break off. A break off is usually an undesirable outcome for both parties, therefore it is important that a negotiator employs a proficient mechanism to decide under which conditions to accept. When designing such conditions one is faced with the acceptance dilemma: accepting the current offer may be suboptimal, as better offers may still be presented. On the other hand, accepting too late may prevent an agreement from being reached, resulting in a break off with no gain for either party. Motivated by the challenges of bilateral negotiations between automated agents and by the results and insights of the automated negotiating agents competition (ANAC), we classify and compare state-of-the-art generic acceptance conditions. We focus on decoupled acceptance conditions, i.e. conditions that do not depend on the bidding strategy that is used. We performed extensive experiments to compare the performance of acceptance conditions in combination with a broad range of bidding strategies and negotiation domains. Furthermore we propose new acceptance conditions and we demonstrate that they outperform the other conditions that we study. In particular, it is shown that they outperform the standard acceptance condition of comparing the current offer with the offer the agent is ready to send out. We also provide insight in to why some conditions work better than others and investigate correlations between the properties of the negotiation environment and the efficacy of acceptance conditions.MediamaticsElectrical Engineering, Mathematics and Computer Scienc
