van Leeuwen, D.A. (author), Truong, K.P. (author), TNO Defensie en Veiligheid (author)This paper introduces a detection methodology for recognition technologies in speech for which it is dif cult to obtain an abundance of non-target classes. An example is language recognition, where we would like to be able to measure the detection capability of a single target language without confounding with the modeling capability of non...conference paper 2007

Truong, K. (author), van Leeuwen, D. (author), TNO Defensie en Veiligheid (author)Emotions can be recognized by audible paralinguistic cues in speech. By detecting these paralinguistic cues that can consist of laughter, a trembling voice, coughs, changes in the intonation contour etc., information about the speakers state and emotion can be revealed. This paper describes the development of a gender-independent laugh detector...article 2007

Truong, K.P. (author), van Leeuwen, D.A. (author), TNO Defensie en Veiligheid (author)In this paper, we introduce a visual analysis method to assess the discriminability and confusiability between emotions according to automatic emotion classifiers. The degree of acoustic similarities between emotions can be defined in terms of distances that are based on pair-wise emotion discrimination experiments. By employing Multidimensional...conference paper 2007

Wetzer, I.M. (author), Zeelenberg, M. (author), Pieters, R. (author), TNO Defensie en Veiligheid (author)What do consumers want to achieve when they engage in negative word-of-mouth communication (N-WOM)? Two studies explore this question and reveal that consumers pursue specific goals when engaging in N-WOM and that these goals systematically differ between the specific negative emotions that are experienced. For example, the results reveal that...article 2007

Evaluating automatic laughter segmentation in meetings using acoustic and acoustic-phonetic featuresTruong, K.P. (author), van Leeuwen, D.A. (author), TNO Defensie en Veiligheid (author)In this study, we investigated automatic laughter segmentation in meetings. We first performed laughterspeech discrimination experiments with traditional spectral features and subsequently used acousticphonetic features. In segmentation, we used Gaussian Mixture Models that were trained with spectral features. For the evaluation of the laughter...conference paper 2007
