Off-talk - a problem for human-machine-interaction?

چکیده
This paper is concerned with the definition and description of the phenomenon Off−Talk in human−machine− interaction. This phenomenon is considered to cause problems due to non−relevant information that is conveyed within these utterances. Besides the definition of Off−Talk our work aims to provide an analysis of transcribed audio data that is part of the SmartKom data collection. In the search for features that could indicate the occurrence of Off−Talk we looked at several speech levels e.g. acoustics, lexicon and prosody. Due to the small amount of available data only three features were examined, as there are: loudness, word frequency and filled pauses. The analysis revealed that a correlation might exist between Off−Talk and all features, so that they may serve as indicators for this phenomenon.

One of the well-known evolutionary algorithms inspired by biological evolution is genetic algorithm (GA) that is employed as a robust and global optimization tool to search for the best or near-optimal solution with the search space. In this paper, this algorithm is used to solve unequalsized machines (or intra-cell) layout problems considering pick-up and drop-off (input/output) points. Such p...

In this paper the FAU IISAH corpus and its recording conditions are described: a new speech database consisting of human-machine and human-human interaction recordings. Beside close-talking microphones for the best possible audio quality of the recorded speech, far-distance microphones were used to acquire the interaction and communication. The recordings took place during a Wizard-of-Oz experi...

متن کاملTaking into Account the User’s Focus of Attention with the Help of Audio-Visual Information: Towards less Artificial Human-Machine-Communication
In the German SmartWeb project, the user is interacting with the web via a PDA in order to get information on, for example, points of interest. To overcome the tedious use of devices such as push-to-talk, but still to be able to tell whether the user is addressing the system or talking to herself or to a third person, we developed a module that monitors speech and video in parallel. Our databas...
