Speech intelligibility is in general lower for older adults than young adults in reverberant environments such as train stations or airports. We aim at to make speech announcements intelligible in public spaces. Speech spoken in noise, i.e., noiseinduced speech, is usually more intelligible than speech spoken in a quiet environment for young people when they are heard in noise, a phenomenon cal...

Clear speech is a speaking style adopted by speakers in an attempt to maximize the clarity of their speech and is proven to be more intelligible than casual speech. This work focuses on modifying casual speech to sound as intelligible as clear speech. First, we examine the role of speaking rate for intelligibility. Clear and casual speech signals are time-scale stretched, matching the average d...

In many schools, English is taught as international communication tool and the goal of English pronunciation training is generally to acquire intelligible enough pronunciation, which is not always native-sounding pronunciation. However, the definition of the intelligible pronunciation is not easy because it depends on the speaking skill of a speaker, the predictability of a content, and the lan...

Noise abatement in office environments often focuses on the reduction of background speech intelligibility and noise level, as attainable with frequency-specific insulation. However, only limited empirical evidence exists regarding the effects of reducing speech intelligibility on cognitive performance and subjectively perceived disturbance. Three experiments tested the impact of low background...

We propose a system to automatically assess the intelligibility of sung lyrics. We are particularly interested in being able to identify songs which are intelligible to second language learners, as such individuals often sing along the song to help them learn their second language, but this is only helpful if the song is intelligible enough for them to understand. As no automatic system for ide...

An intelligible program diagram called Logichart has been developed for Prolog visualization. Its syntax rules and layout rules are formalized in terms of an attribute graph grammar. This grammar consists of a context–free graph grammar whose productions are defined in such a way as to formalize the graph–syntax rules of Logichart diagrams, and semantic rules which are defined in such a way tha...

When a dataset involves multiple classes, there is often a need to express the key contrasting features among these classes in humanly understandable terms, that is, to pro"le the classes. Commonly, one class is contrasted from the rest by aggregating the latter into a pseudo-class; alternatively, classes are treated separately without coordinating their pro"les with those of the other classes....
