Translog-II Carl, Michael This paper presents a novel implementation of Translog-II. Translog-II is a Windows-oriented program to record and study reading and writing processes on a computer. In our research, it is an instrument to acquire objective, digital data of human translation processes. As their predecessors, Translog 2000 and Translog 2006, also Translog-II consists of two main components: Translog-II Supervisor and Translog-II User, which are used to create a project file, to run a text production experiments (a user reads, writes or translates a text) and to replay the session. Translog produces a log files which contains all user activity data of the reading, writing, or translation session, and which can be evaluated by external tools. While there is a large body of translation process research based on Translog, this paper gives an overview of the Translog-II functions and its data visualization options.

Assigning Students in Groups Razmerita, Liana; Brun, Armelle Group work has been adopted as an important tool to support collaborative work in order to enhance learning processes. There is a wealth of literature related to group performance and the impact of group composition on group and individual performance. However, very few studies address the issue on how to automatically form groups. This article proposes a methodology that could be used by professors to form groups automatically taking into account different criteria as well as the students’ profile. This methodology is based on a pilot study that analyzes group composition of self-formed student groups.

Information based speech transduction Juel Henrichsen, Peter Modern hearing aids use a variety of advanced digital signal processing methods in order to improve speech intelligibility. These methods are based on knowledge about the acoustics outside the ear as well as psychoacoustics. We present a novel observation based on the fact that acoustic prominence is not equal to information prominence for time intervals at the syllabic and sub-syllabic levels. The idea is that speech elements with a high degree of information can be robustly identified based on basic acoustic properties. We evaluated the correlation of (information rich) content words in the DanPASS corpus with fundamental frequency (F0) and spectral tilt across four frequency bands. Our results show a correlation of certain band-level differences and the presence of content words. Similarly, but to a lesser extent, a correlation between F0 and the presence of content words was found. The principle described here has the potential to improve the “information-to-noise” ratio in hearing aids. In addition, this concept may also be applicable in automatic speech recognition systems.

Objective Evaluation of Consonant-Vowel pairs produced by Native Speakers of Danish Christiansen, Thomas U.; Juel Henrichsen, Peter Nonsense syllable speech materials are often used when investigating speech perception in quiet and under adverse conditions. The main advantage of using nonsense syllables over words and sentences is that the acoustic as well as the linguistic context is minimal. This paper presents three anechoic recordings of 13 male and 13 female native talkers of Danish each speaking 65 nonsense syllables repeated three times with the neutral intonation contour for Danish (in total 15210 syllables). The authors compared and ranked groups of three recordings. These three recording had the same talker and had identical phonetic content. The syllables were ranked according to the general “appropriateness” and consistency, i.e., prototypical production of the consonant-vowel (CV) with respect to applicability in speech perceptual studies. The results were compared to results of an automatic method based on acoustic measures. The two novel ideas are 1) to devise an automated method for evaluating “appropriateness” of CVs and 2) to develop a Danish CV-material annotated with an objective measure of “appropriateness” for each recorded CV. The latter would potentially render more CV’s appropriate for perceptual studies. Moreover, objective evaluation would make it possible to examine any perceptual effects of variability in CV production (for example how susceptible different renderings by the same talker of CV’s are to background noise). To the knowledge of the authors, no such material has yet been published for any language.
