This paper presents a methodology of parametric tolerance synthesis with respect to output aleatory uncertainty specifications. It relies on density function propagation through the inverse model. The resulting parameter density function is then used to synthesize a confidence interval suitable for sizing purpose. As an illustration, parametric tolerance synthesis on a DC motor rotating a load ...

This is a summary of studies of word and syllable prominence in Swedish performed during several years. A unique feature is the correlation of observed acoustic data with a continuously scaled parameter of perceived prominence. Besides the established parameters of duration, F0, intensity, and spectral tilt we have also data on true subglottal pressure. Studies of co-variation within the set of...

Typography plays an important role in publishing industry, and typically different typographies are needed for different use cases. However, designing a new font is very expensive and time-consuming, especially for Chinese, which involves a huge amount of characters. Some semi-automatic typography synthesis approaches have been proposed. These methods utilize structural commonalities to simplif...

In this paper we present a concept for a wide-ranging indoor navigation support for the blind and people with impaired vision. Parts of this work were realized within a new prototype of an indoor navigation and object identification system for the blind. With the previous orientation assistant it is possible for blind persons to orientate themselves and to detect objects within modeled indoor e...

In this paper, we present a new approach for the speech synthesis, in which speech utterances are synthesized using the parameters of spectro-modeling function (Multiple function). With this approach, only harmonic-parts are extracted from the phoneme spectrum, and the time-varying spectrum corresponding to the harmonics or sinusoidal components is modeled using the Multiple function. We introd...

By means of a pair comparison test, preferences of German native speakers for English or German sounds in spoken anglicisms were investigated. The collected data can be used as a reference point, which of the English xenophones have to be integrated into a German TTS system to allow for an appropriate pronunciation of anglicisms in German.

In most languages, the quality of a speech synthesis system relates directly to the diversity of language domain. Each domain, such as sports, entertainments, etc., has its specific grammar structures. The grammar structure plays as an important role for analyzing the prosodic information of utterances in each domain. In this research, we will analyze characteristics of prosodic information of ...
