Speech of children with cleft lip and palate (CLP) is sometimes still disordered even after adequate surgical and nonsurgical therapies. Such speech shows complex articulation disorders, which are usually assessed perceptually, consuming time and manpower. Hence, there is a need for an easy to apply and reliable automatic method. To create a reference for(More)
OBJECTIVE Cleft lip and palate (CLP) may cause functional limitations even after adequate surgical and non-surgical treatment, speech disorders being one of them. Interindividually, they vary a lot, showing typical articulation specifics such as nasal emission and shift of articulation and therefore a diminished intelligibility. Until now, an objective(More)
PURPOSE In the community of x-ray imaging, there is a multitude of tools and applications that are used in scientific practice. Many of these tools are proprietary and can only be used within a certain lab. Often the same algorithm is implemented multiple times by different groups in order to enable comparison. In an effort to tackle this problem, the(More)
Normally, mobile pedestrian navigation systems use visually perceptible landmarks to guide their users through the environment. In this article we introduce concepts for the use of auditory perceptible landmarks in route descriptions. Such auditory perceptible landmarks complement their visual counterparts and also stand to be beneficial for certain groups(More)
Today, the demand for software that is 'intuitive to use' is very high. In fact, this has become a determining factor for the success of a system. However, building software that is intuitive to use is challenging. This is particularly true for small and medium-sized enterprises (SMEs). They have to face a variety of problems to remain competitive: Usually(More)
There are several methods to create visualizations of speech data. All of them, however , lack the ability to remove microphone-dependent distortions. We examined the use of Principal Component Analysis (PCA), Linear Discriminant Analysis (LDA), and the COmprehensive Space Map of Objective Signal (COSMOS) method in this work. To solve the problem of lacking(More)
Mit neuen Technologien entstehen auch neue Interaktionskonzepte. Beispiels-weise kann man eine Telefonnummer mittlerweile durch das Drehen einer Wählscheibe (wer erinnert sich noch?), dem Drücken der Tasten des Num-mernblocks, aber auch mittels Touchdisplay, Sprach-oder Gestens-teuerung eingeben. Doch welche dieser Varianten ist die beste? Und wo genau(More)
