This study proposes a two-pass spoken term detection (STD) method. The first pass uses a phoneme-based dynamic time warping (DTW)-based STD, and the second pass recomputes detection scores produced by the first pass using conditional random fields (CRF)-based triphone detectors. In the second-pass, we treat STD as a sequence labeling problem. We use CRF-based triphone detection models based on ...

OBJECTIVE The Heidelberg Phoneme Discrimination Test (HLAD), developed and standardized in 1998, is widely used in the differential diagnosis of dyslexia. Normative data have only been available for children of the 2nd and 4th grades, while norms for the 3rd grade are still missing. PATIENTS AND METHODS We assessed three HLAD subtests [auditory phoneme discrimination, kinesthetic phoneme disc...

OBJECTIVES The aim was to explore whether word-initial onset awareness is acquired before phoneme awareness and whether onset complexity influences performance on identification tasks. In addition, the relationship between onset and phoneme awareness and letter knowledge was investigated. METHOD In this study, 22 monolingual German-speaking preschool children aged 5;00-5;11 were tested. Onset...

Speech recognition has gradually improved over the years, phoneme recognition in particular. Phoneme recognition plays very important role in speech processing. Phoneme strings are basic representation for automatic language recognition and it is proved that language recognition results are highly correlated with phoneme recognition results. Nowadays, many recognizers are based on Artificial ne...

Collections of speech documents can be searched using speech retrieval, in which the documents are processed by a speech recogniser to give text that can be searched by standard text retrieval techniques. Recognition is the translation of speech signals into either words or subword units such as phonemes. We investigated the use of a phoneme-based recogniser to obtain phoneme sequences. We foun...

In this paper, we propose phoneme duration modeling methods with tree-based state tying. Two kinds of phone duration modeling methods are suggested. The first is context independent phoneme duration model in which duration parameters are stored in each phone. The second is context dependent duration model in which duration parameters are stored in each state being shared by context dependent ph...

In the present study, we examined the distribution and processing of information over time in auditory and visual speech as it is used in unimodal and bimodal word recognition. English consonant-vowel-consonant words representing all possible initial consonants were presented as auditory, visual, or audiovisual speech in a gating task. The distribution of information over time varied across and...

Two experiments sought to extend the demonstration of English-learning infants' abilities to segment nouns from fluent speech to a new lexical class: verbs. Moreover, we explored whether two factors previously shown to influence noun segmentation, stress pattern (strong-weak or weak-strong) and type of initial phoneme (consonant or vowel), also influence verb segmentation. Our results establish...

In a word-naming experiment, word-body consistency was crossed with grapheme-to-phoneme regularity to test predictions of current models of word recognition. In the latency and error data, a clear effect of consistency was observed, with the influence of regularity somewhat weaker. In addition, simulation data from three contemporary models of word recognition were obtained for the stimuli used...
