A variety of approaches to language identiication, based on (a) acoustic features, (b) broad-category segmentation, and (c) ne phonetic classiication, are introduced. These approaches are evaluated in terms of their ability to distinguish between English and Japanese utterances spoken over a telephone channel. It is found that the best performance (86.3 % accurate classiication of utterances wi...

The purpose of this study was to evaluate whether increased utterance length and grammatical complexity are associated with changes in frequency of systematic speech errors (i.e., phonological processes, or sound changes affecting an entire class of sounds or sound sequence [Edwards & Shriberg, 1983]), and nonsystematic speech errors (i.e., a word or string of words that apparently deviates fro...

This study examines some intonational and rhythmical aspects of speech and their interactions. The intonational analysis framework is the ToBi system; the rhythmical analysis framework is based on patterns of jaw opening acoustically reflected by F2-F1 changes. According to recent studies on American English, contrastively emphasized mono-syllabic words, regardless of vowel height, have larger ...

this study is an attempt to answer three questions: first, whether there is a difference between the grammatical competence de- velopment of a group of children aged 2;6 vs. a group of children aged 3;6. second, whether there is a relationship between the children’s age and their mlu on the one hand and their speech and the caretakers’ speech on the other. third, whether or not the normal limit...

We introduce a novel method for bilingual phrase representation with Recurrent Neural Networks (RNNs), which transforms a sequence of word feature vectors into a fixed-length phrase vector across two languages. Our method measures the difference between the vectors of sourceand target-side phrases, and can be used to predict the semantic equivalence of source and target word sequences in the ph...

Slovak allows us to compare vowels and consonants (/l/ and /r/) in nuclear position for their implementation of phonemic length contrast in stressed as well as unstressed syllables of accented as well as unaccented words. We analyzed the acoustic data of seven speakers for the changes in the duration of the vocalic and consonantal nuclei induced by phonemic length contrast and phrasal accent fo...
