A new voice conversion method that improves the quality of the voice conversion output at higher sampling rates is proposed. Speaker Transformation Algorithm Using Segmental Codebooks (STASC) is modified to process source and target speech spectra in different subbands. The new method ensures better conversion at sampling rates above 16KHz. Discrete Wavelet Transform (DWT) is employed for subba...

Often user interfaces of theorem proving systems focus on assisting particularly trained and skilled users, i.e., proof experts. As a result, the systems are difficult to use for non-expert users. This paper describes a paper and pencil experiment, in which (non-expert) students were asked to make suggestions for a GUI for an interactive system for mathematical proofs. They had to explain the u...

The role of the tutor is important in developing effective group process in educational programs built around smallgroup, problem-based learning (PBL). The tutor’s role includes creating a supportive group climate, encouraging the involvement of group members and addressing group problems when they arise. Good tutoring has the potential to enhance group process in both novice and experienced te...

The amount of health information on the internet is constantly growing but little is done for detecting the technicality level of these documents and guiding of users towards documents which are appropriate to their expertise level. The objective of our work is to propose clues for the automatic distinction between expert and non expert medical documents. More precisely, we propose to study the...

Thousands of web APIs expose data and services that would be useful to access with natural dialog, from weather and sports to Twitter and movies. The process of adapting each API to a robust dialog system is difficult and time-consuming, as it requires not only programming but also anticipating what is mostly likely to be asked and how it is likely to be asked. We present a crowd-powered system...

Proper use of an anonymity system requires adequate understanding of how it functions. Yet, there is surprisingly little research that looks into user understanding and usage of anonymity software. Improper use stemming from a lack of sufficient knowledge of the system has the potential to lead to deanonymization, which may hold severe personal consequences for the user. We report on the unders...
