Language learners need to map a continuous, multidimensional acoustic signal to discrete abstract speech categories. The complexity of this mapping poses a difficult learning problem, particularly for second language learners who struggle to acquire the speech sounds of a non-native language, and almost never reach native-like ability. A common…

Purpose: Older native speakers of English have difficulty in understanding Spanish-accented English compared to younger native English speakers. However, it is unclear if this age effect would be observed among native speakers of Spanish. The current study investigates the effects of age and native language experience with Spanish on the ability…

When it comes to paying attention to the suprasegmental features of their speech, most learners of English seem to be unaware that such phenomena as stress, pitch, duration, and pausing can be of great importance regarding mutual intelligibility. Since they carry a considerable weight of establishing an intelligible conversation, it is argued that…

North Kyungsang Korean (NKK) is a pitch accent language in which each word has one of a restricted set of possible tonal patterns, and where the tonal pattern of a given lexical word is not fully predictable. This dissertation reports on a corpus study of accent patterns in existing words and the results of a study in which NKK speakers were asked…

Systematic differences among regional U.S. English speech are recognizable to native speakers to varying degrees. This has been demonstrated by researchers in perceptual dialectology who ask listeners to match a speaker to his or her dialect region. Machines have also been able to identify the regional origin of a speaker to some degree, although…

This paper outlines the ongoing construction of a speech corpus for use by applied linguists and advanced EFL/ESL students. In the first part, sections 1-4, the need for improvements in the teaching of listening skills and pronunciation practice for EFL/ESL students is noted. It is argued that the use of authentic native-to-native speech is…
