VERBMOBIL is a speech-to-speech translation system for spoken dialogues between two speakers. The application scenario is appointment scheduling for business meetings, with spoken dialogues between two speakers. Both dialogue participants have at least a passive knowledge of English which serves as intermediate language. The transfer directions are German to English and Japanese to English. A s...

A virtual reality (VR) system tracks one or more objects to generate the depiction of a virtual environment from the user’s vantage point. No system achieves this instantaneously: changes in the depicted virtual environment are delayed from changes in the position of the objects being tracked. In this paper, a method is proposed to quantify this time difference, the end-to-end delay of the VR s...

We address the problem of speaker age estimation using ivectors. We first compare different i-vector extraction setups and then focus on (shallow) artificial neural net (ANN) backends. We explore ANN architecture, training algorithm and ANN ensembles. The results on NIST 2008 and 2010 SRE data indicate that, after extensive parameter optimization, ANN back-end in combination with i-vectors reac...
