This study aims at discussing the phonetic property of vowel quality in English, as exercised by both native speakers of General American English (AE) and non-native speakers of General American English of Serbian language background, all residents of the United States. Ten Serbian male speakers and four native male speakers of AE are recorded in separate experiments and their speech analyzed acoustically for any significant phonetic differences, looking into a set of monosyllabic English words representing nine vowels of AE. The general aim of the experiments is to evaluate the phonetic characteristics of AE vowels, with particular attention to F1 and F2 values, investigate which vowels differ most in the two groups of participants, and provide some explanations for these variations. A single most important observation that is the result of this vowel study is an evident merger of three pairs of vowels in the non-native speech: /i ɪ/, /u ʊ/, and /ɛ æ/.

AbstractIn many languages, declaratives and interrogatives differ in word order properties, and in syntactic organization more broadly. Thus, in order to learn the distinct syntactic properties of the two sentence types, learners must first be able to distinguish them using non-syntactic information. Prosodic information is often assumed to be a useful basis for this type of discrimination, although no systematic studies of the prosodic cues available to infants have been reported. Analysis of maternal speech in three Standard American English-speaking mother–infant dyads found that polar interrogatives differed from declaratives on the patterning of pitch and duration on the final two syllables, butwh-questions did not. Thus, while prosody is unlikely to aid discrimination of declaratives fromwh-questions, infant-directed speech provides prosodic information that infants could use to distinguish declaratives and polar interrogatives. We discuss how learners could leverage this information to identify all question forms, in the context of syntax acquisition.

Maternal Speech

Purpose Caregivers may show greater use of nonauditory signals in interactions with children who are deaf or hard of hearing (DHH). This study explored the frequency of maternal touch and the temporal alignment of touch with speech in the input to children who are DHH and age-matched peers with normal hearing. Method We gathered audio and video recordings of mother–child free-play interactions. Maternal speech units were annotated from audio recordings, and touch events were annotated from video recordings. Analyses explored the frequency and duration of touch events and the temporal alignment of touch with speech. Results Greater variance was observed in the frequency of touch and its total duration in the input to children who are DHH. Furthermore, touches produced by mothers of children who are DHH were significantly more likely to be aligned with speech than touches produced by mothers of children with normal hearing. Conclusion Caregivers' modifications in the input to children who are DHH are observed in the combination of speech with touch. The implications for such patterns and how they may impact children's attention and access to the speech signal are discussed.

The present study investigates the acoustic characteristics of Greek vowels produced by hearing-impaired children with profound prelingual hearing loss and cochlear implants. The results revealed a significant difference between vowels produced by hearingimpaired children and those produced by normal-hearing ones in terms of duration. Stressed vowels were significantly longer than non-stressed for both groups, while F0, F1 and F2 did not differ significantly between the two groups for any vowel, with the exception of /a/, which had significantly higher F1 when produced by hearingimpaired children. Acoustic vowel spaces were similar for the two groups but shifted towards higher frequencies in the low-high dimension and somehow reduced in the front-back dimension for the hearing-impaired group.
