York, where we made high quality audio recordings of all members performing sygyt.</p>
<p>In collaboration with the MRI facility at York, we were able to capture dynamic 2D sagittal and

<h4>The intersections of infant speech perception and phonological typology</h3>
</div>
<!-- description -->
<div class="card-body">Patterns observed in language acquisition often resemble trends in the diachronic
history of languages. For example, Jakobson famously noticed the correlation between age of
acquisition of a particular consonant and how often the consonant is found in the world's languages.
Our research extends these ideas by examining the intersections of historical phonology, typology,
acoustics, and the nature of infant speech perception.

<h4>Acoustics of infant-directed speech</h3>
</div>
<!-- description -->
<div class="card-body">Supported by a Standard Research Grant from the SSHRC, we are transcribing the
Cross-Linguistic Corpus of Infant-Directed Speech (CCIDS), which is a collection of high-quality
recordings of mother-infant dyads in three less-studied languages: Sri Lankan Tamil, Tagalog, and
Korean. The goal of the completed CCIDS is to have accessible to linguists, psychologists, and
speech researchers, a phoneme-aligned and transcribed corpus for phonetic, phonological,
morphological and syntactic analysis.

<h4>Language and lower-level perception</h3>
</div>
<!-- description -->
<div class="card-body">The lab explores the relationship between speech processing and lower levels of
cognition, namely talker discrimination. Together with colleagues from York Psychology, UTSC, and
UBC, we're beginning to understand that listeners cannot avoid processing speech linguistically,
even when their task is listen for indexical characteristics of talkers' voices. We are also
interested in the interaction (if there is one), between language and speech processing and spatial
awareness, namely, whether pitch height (and by proxy linguistic tone) are represented by naive
listeners in two-dimensional space. We are also examining the role low-level acoustics in perceptual
learning of noise-vocoded words and sentences.
