“…It would therefore be interesting to investigate the possibility of covert phonetic contrasts on children's apparent omission of third person singular -s. This suggests that further acoustic analysis, both of the input children hear (cf. Newman, Clouse, & Burnham, 2001) and of child productions, would provide further evidence of this morpheme in children's underlying phonological representations.…”

Phonological Constraints on Children's Production of English Third Person Singular -sPurpose: Children variably produce grammatical morphemes at early stages of development, often omitting inflectional morphemes in obligatory contexts. This has typically been attributed to immature syntactic or semantic representations. In this study, the authors investigated the hypothesis that children's variable production of the 3rd person singular morpheme -s interacts with the phonological complexity of the verb stem to which it is attached. Method: To explore this possibility, the authors examined longitudinal data from the spontaneous speech of 6 English-speaking children between ages 1;3 and 3;6 (years; months) and elicited imitations from a cross-sectional study of 23 two-year-olds (mean age of 2;2). Results: The results showed that children produced third person singular morphemes more accurately in phonologically simple coda contexts (e.g., sees) as compared with complex coda contexts (e.g., needs). In addition, children produced -s more accurately in utterance-final position as compared with utterance-medial position. Conclusions:The results provide strong support for the role of phonological complexity in explaining some of the variability in children's production of third person singular -s. This finding suggests that future research will need to consider multiple factors, including phonological and positional effects, in constructing a comprehensive developmental theory of both grammatical competence and processes of speech planning and production.

“…However, it is known that speakers of a language exhibit individual differences for a variety of phonetic categories, for both production (Hillenbrand et al 1995, Peterson and Barney 1952, Newman et al 2001, Allen et al 2003, Byrd 1992, Zue & Laferriere 1979, Espy-Wilson et al 2000, Hashi et al 2003 and perception (Liberman et al, 1957;Theodore et al, 2013). Fitting the model to aggregate rather than individual participants' data could affect our inferences about where individual phonemes are located on the τ continuum.…”

A unified account of categorical effects in phonetic perception

Categorical effects are found across speech sound categories, with the degree of these effects ranging from extremely strong categorical perception in consonants to nearly continuous perception in vowels. We show that both strong and weak categorical effects can be captured by a unified model. We treat speech perception as a statistical inference problem, assuming that listeners use their knowledge of categories as well as the acoustics of the signal to infer the intended productions of the speaker. Simulations show that the model provides close fits to empirical data, unifying past findings of categorical effects in consonants and vowels and capturing differences in the degree of categorical effects through a single parameter.

“…The /p-b/ VOT contrast and the /s-∫/ contrast were chosen because they have previously been used to examine speaker variability in speech production (e.g. Allen, Miller, & DeSteno, 2003;Newman, Clouse, & Burnham, 2001;Theodore, Miller, & DeSteno, 2009). The 36 keywords were divided into three sets, and each set of 12 was used for a different picture theme (i.e.…”

The renewed focus of attention on investigating spontaneous speech samples in speech and language research has increased the need for recordings of speech in interactive settings. The DiapixUK task is a new and extended set of picture materials based on the Diapix task by Van Engen et al. (Language and Speech, 53, 510-540, 2010), where two people are recorded while conversing to solve a 'spot the difference' task. The new task materials allow for multiple recordings of the same speaker pairs due to a larger set of picture pairs that have a number of tested features: equal difficulty across all 12 picture pairs, no learning effect of completing more than one picture task and balanced contributions from both speakers. The new materials also provide extra flexibility, making them useful in a wide range of research projects; they are multi-layered electronic images that can be adapted to suit different research needs. This article presents details of the development of the DiapixUK materials, along with data taken from a large corpus of spontaneous speech that are used to demonstrate its new features. Current and potential applications of the task are also discussed.Keywords Speech corpora . Spontaneous speech . Test design Speech produced during an interaction differs from read speech in lexical and grammatical content (e.g. Blauuw, 1994), in segmental phonetic characteristics and in prosodic characteristics (e.g. Lann & Van Bergem, 1993), which explains why these two speech styles are perceptually distinguishable even if they contain the same speech material. Despite these differences, many studies still use read speech to investigate research topics such as the acoustic-phonetic characteristics of different speaking styles. Undoubtedly, spontaneous interactive speech recordings are challenging to process and analyse, but the increased ability to generalise results from these data to naturally occurring speech makes this challenge worth overcoming. Of the studies that have investigated interactive speech, many have used problem-solving tasks to elicit speech in a controlled setting, in an attempt to record conversations with similar topics and structures. This article describes the development of a set of materials (DiapixUK) which extend the recently developed Diapix task (Van Engen et al., 2010)-an easy way to collect spontaneous dialogs between two speakers, while having some control over the lexical content of the discourse. The task involves two people conversing to find differences between two versions of the same picture. The three picture pairs designed by Van Engen et al. are suited to American English participants, and the picture content cannot be easily altered. The new DiapixUK picture materials make this methodology suitable to the needs of a wider range of researchers and are also potentially suitable for use in clinical settings. The 12 new picture pairs, which have been standardised and shown to be of equal difficulty, provide ample material for the elicitation of interactive speech over...
