Discriminative Power of transient frames in speaker recognition
International Conference on Acoustics Speech and Signal Processing, 2005Co-Authors: Jerome Louradour, Khalid Daoudi, Regine AndreobrechtAbstract:In speaker recognition, several recent studies attempt to integrate prior knowledge in order to make better distinction between speakers. This paper studies the relative speaker Discriminative Power of speech transient and steady zones. An automatic segmentation is used to localize these two types of zones. Experiments are carried out with the KIST 2003 speaker evaluation database. They show that transient frames, in the neighborhood of segment boundaries, are more speaker Discriminative than the middle frames of long segments which correspond to the steady parts of phones. In addition, this study leads to a higher efficiency system (than the baseline one) by processing roughly three times less data during the scoring stage.

Short-time weight-bearing capacity assessment for non-ambulatory patients with subacute stroke: reliability and Discriminative Power
BMC research notes, 2015Co-Authors: Oliver Stoller, Heike Rosemeyer, Heiner Baur, Matthias Schindelholz, Kenneth J. Hunt, Lorenz Radlinger, Corina Schuster-amftAbstract:Weight-bearing capacity (WBC) on the hemiparetic leg is crucial for independent walking, and is thus an important outcome to monitor after a stroke. A specific and practical assessment in non-ambulatory patients is not available. This is of importance considering the increasing administration of high intensive gait training for the severely impaired stroke population. The aim was to develop a fast and easy-to-perform assessment for WBC on a foot pressure plate to be used in clinical routine. WBC was assessed in the frontal plane in 30 non-ambulatory patients with subacute stroke and 10 healthy controls under 3 conditions: static, dynamic, and rhythmic. Force–time curves for the hemiparetic leg (patients with stroke) and the non-dominant leg (healthy controls) were normalised as a percentage of body weight (%BW), and the means analysed over 60, 30, and 15 s (static) and the mean of the peak values for 15, 10, 5, 4, and 3 repetition trials (dynamic, rhythmic). The data were tested for Discriminative Power and reliability. Dynamic and rhythmic tests could discriminate between patients with stroke and healthy controls over all periods (15, 10, 5, 4, and 3 repetitions) (p 0.829] and inter-session reliability (ICC = 0.740) were found for 3 repetitions in the dynamic test with acceptable absolute reliability [standard error of measurement (SEM)

short time weight bearing capacity assessment for non ambulatory patients with subacute stroke reliability and Discriminative Power

Three dynamic repetitions of loading the hemiparetic leg are sufficient to assess WBC in non-ambulatory patients with subacute stroke. This is an important finding regarding the implementation of a fast and easy-to-perform assessment for routine clinical usage in patients with limited standing ability.
