Speech is considered an efficient communication channel. This implies that the organization of utterances is such that more speaking effort is directed towards important parts than towards redundant parts. Based on a model of incremental word recognition, the importance of a segment is defined as its contribution to word-disambiguation. This importance is(More)

Several recent studies have shown that speech production develops in an organized way, already in the first twelve months of life. This development is determined by several factors such as anatomical growth and physiological constraints. Studying the sound production of deaf infants and comparing this with that of normally hearing infants, can give more(More)
It is proposed that some of the variation in speech is the result of an effort to communicate efficiently. Speaking is considered efficient if the speech sound contains only the information needed to understand it. This efficiency is tested by means of a corpus of spontaneous and matched read speech, and syllable, word, and N-gram frequencies as measures of(More)
As a result of the cooperation in the Intas 915 project, annotated speech corpora have become available in three different languages for both read and spontaneous speech of some 4-5 male and 4-5 female speakers per language (6-10 minutes per speaker). These data have been used to study the effects of redundancy on acoustic vowel reduction, in terms of vowel(More)
