Although the confusion of individual phonemes and features have been studied and analyzed since Miller and Nicely [8], there has been little work done on extending this to a predictive theory of word-level confusions. The PGPfone alphabet is a good touchstone problem for developing such word-level confusion metrics. This paper presents some difficulties incurred, along with their proposed solut...

This study explored the neural systems underlying the perception of phonetic category structure by investigating the perception of a voice onset time (VOT) continuum in a phonetic categorization task. Stimuli consisted of five synthetic speech stimuli which ranged in VOT from 0 msec ([da]) to 40 msec ([ta]). Results from 12 subjects showed that the neural system is sensitive to VOT differences ...

The study investigated effect of phonological regularity of phonetic compound characters on writing and its development. Students from grade 2, 4 and 6 with normal non-verbal IQ, Chinese reading ability and visual-spatial perceptual abilities were recruited. Writing to dictation on 16 characters, embedded in compound words, with phonological regularity, character frequency and stroke number con...

A patient who already had Wernicke's aphasia due to a left temporal lobe lesion suffered a severe deterioration specifically of auditory language comprehension, subsequent to right temporal lobe infarction. A detailed comparison of his new condition with his language status before the second stroke revealed that the newly acquired deficit was limited to tasks related to auditory input. Further ...

This study proposes a framework of automatic analysis and recognition of accentual patterns. In the first place we present the results of analyses which aimed at identification of acoustic cues signaling prominent syllables and different pitch accent types distinguished at the surface-phonological level. The resulting representation provides a framework of analysis of accentual patterns at the ...

There is an increasing need for automatic procedures to generate and validate phonetic transcriptions. As the production of manual phonetic transcriptions tends to be time-consuming, error-prone and costly, procedures have been developed to derive phonetic transcriptions automatically by means of automatic speech recognition technology. Such automatic phonetic transcriptions are usually validat...

Speaker variability has a significant impact to the state-of-the-art speech recognition systems. Traditionally speaker clustering is performed without considering individual or class phonetic similarities across different speakers. In fact, clustered speaker groups may have very different degrees of variations for different phonetic classes. In this paper, speaker clustering is performed at sub...

We present SingaKids-Mandarin, a speech corpus of 255 Singaporean children aged 7 to 12 reading Mandarin Chinese, for a total of 125 hours of data (75 hours of speech) and 79,843 utterances. This corpus is phonetically balanced and detailed in human annotations, including phonetic transcriptions, lexical tone markings, and proficiency scoring at the utterance level. The reading scripts span a d...
