We present the open-source extensible dialog manager DialogOS.
DialogOS features simple finite-state based dialog management
(which can be expanded to more complex DM strategies via a full-fledged scripting language) in combination with integrated speech recognition and synthesis in multiple languages.
DialogOS runs on all major platforms, provides a simple-to-use
graphical interface and can easily be extended via well-defined
plugin and client interfaces, or can be integrated server-side into
larger existing software infrastructures. We hope that DialogOS
will help foster research and teaching given that it lowers the bar
of entry into building and testing spoken dialog systems and provides paths to extend one’s system as development progresses.
The relation of syntax and prosody (the syntax-prosody interface) has been an active area of research, mostly in linguistics and typically studied under controlled conditions. More recently, prosody has also been successfully used in the data-based training of syntax parsers. However, there is a gap between the controlled and detailed study of the individual effects between syntax and prosody and the large-scale application of prosody in syntactic parsing with only a shallow analysis of the respective influences. In this paper, we close the gap by investigating the significance of correlations of prosodic realization with specific syntactic functions using linear mixed effects models in a very large corpus of read-out German encyclopedic texts. Using this corpus, we are able to analyze prosodic structuring performed by a diverse set of speakers while they try to optimize factual content delivery. After normalization by speaker, we obtain significant effects, e.g. confirming that the subject function, as compared to the object function, has a positive effect on pitch and duration of a word, but a negative effect on loudness.
