We are looking for a mathematical model of monophonic sounds with independent time and phase dimensions. With such a model we can resynthesise a sound with arbitrarily modulated frequency and progress of the timbre. We propose such a model and show that it exactly fulfils some natural properties, like a kind of timeinvariance, robustness against non-harmonic frequencies, envelope preservation, ...

For many centuries "rMias been the conventional wisdom that 'language' is one of the essential features that differentiates humans from other primates. However, the past quarter-century has witnessed an explosion in our understanding of the linguistic, psychological, physiological, and developmental aspects of language, and with these advances the uniqueness of language among Homo sapiens has f...

Adaptation to the user is of great importance in a language training system since the user, making unfamiliar, socially unacceptable sounds, must be made to feel self-confident in order to obtain best results. The Fluency project aims at creating a pronunciation trainer for foreign language learning. It uses automatic speech recognition (CMU’s SPHINX II) and is guided by basic principles in for...

For statistical learning to aid in language learning, learners must resolve statistical information along multiple dimensions of the same linguistic signal. Given that infants show evidence of lexical knowledge while they are still learning how to categorize speech, infant learners are likely presented with at least two statistical learning problems simultaneously. In an effort to approximate t...

In listening to speech, one typically reduces the number and variety of the many sounds with which he is bombarded by casting them into one or another of the phoneme categories that his language allows. Thus, a listener will identify as b, for example, quite a large number of acoustically different sounds. Although these differences are likely to be many and various, some of them will occur alo...

Specific Language Impairment (SLI) is a developmental disorder affecting language learning across a number of domains. These difficulties are thought to be related to difficulties processing auditory speech, given findings of imperfect auditory processing across nonspeech tones, individual speech sounds and syllables. However the relationship of auditory difficulties to language development rem...
