This Thursday, March 2nd, Amanda Rysling (UMass Amherst) will be giving a colloquium talk at 1:30pm in Humanities 2, Room 259. Her talk is entitled “Preferential early attribution in segmental perception” and the abstract is given below.

Recognizing the speech we hear as the sounds of the languages we speak requires solving a parsing problem: mapping from the acoustic input we receive to the sounds and words we recognize as our language. The way that listeners do this impacts the phonologies of the world’s languages.

Most work on segmental perception has focused on how listeners successfully disentangle the effects of segmental coarticulation. An assumption of this literature is that listeners almost always attribute the acoustic products of articulation to the sounds whose articulation created those products. As a result, listeners usually judge two successive phones to be maximally distinct from each other in clear listening conditions. Few studies (Fujimura, Macchi, & Streeter, 1978; Kingston & Shinya, 2003; Repp, 1983) have examined cases in which listeners seem to systematically “mis-parse” (Ohala, 1981; et seq.), hearing two sounds in a row as similar to each other, and apparently failing to disentangle the blend of their production. I advance the hypothesis that listeners default to attributing incoming acoustic material to the first of two phones in a sequence, even when that material includes the products of the second phone’s articulation. I report studies which show that listeners persist in attributing the acoustic products of a second sound’s articulation to a first sound even when the signal conveys early explicit evidence about the identity of that second sound. Thus, in cases in which listeners could have leveraged articulatory information to begin disentangling the first sound from the second, they did not do so. I argue that this behavior arises from a domain-general perceptual bias to construe temporally distributed input as evidence of one event, rather than two.

These results support a new conceptualization of the segmental parsing problem. Since listeners necessarily perceive events in the world at a delay from when those events occurred, it may be adaptive to attribute the incoming signal to an earlier speech sound when no other determining information is available. There are cases in which listeners do not disentangle the coarticulated acoustics of two sequential sounds, because they are not compelled to do so. Finally, I argue that this has affected the phonologies of the world’s languages, resulting in, for example, predominantly regressive assimilation of major place features.

Join us this Tuesday, February 21st, for a colloquium talk by Sam Zukoff (MIT), at 1:30pm in Hum 2, room 259. His talk is entitled “Stress Restricts Reduplication” and the abstract is given below:

This paper considers the typology of reduplicant shape, and argues that a system with freelyrankable templatic constraints on reduplicant size/shape over-generates. A survey of Australian languages with quantity insensitive left-to-right alternating cyclic stress systems finds that monosyllabic prefixal reduplicants are not attested; all prefixal partial reduplication patterns in such languages are disyllabic. The disyllabic pattern allows for complete satisfaction of all otherwise undominated stress constraints, whereas any monosyllabic reduplicant would induce violation of one of these constraints. The typological absence of the monosyllabic pattern in these languages thus follows only if templatic constraints (“Reduplicant Size”) must be subordinated to otherwise undominated stress constraints (“Stress Requirements”). This is captured through a meta-ranking condition on the phonological grammar: StressReq >> RedSize (S>>R). The paper further explores how this meta-ranking is compatible with prosodically variable yet predictable reduplicant shape in Ponapean, and an apparently problematic case of monosyllabic reduplication in Ngan’gityemerri which turns out to be the exception that proves the rule.

Our second talk this week will be Thursday, February 23rd, given by Ryan Bennett (Yale), at 1:30pm in Hum 1, room 202. His talk is entitled “Idiosyncrasy and contextual variability in the prosody of functional morphemes” and the abstract is given below:

Dependent morphemes (affixes, clitics) may idiosyncratically select for prosodic properties of their hosts (Inkelas 1990, Zec 2005, etc.). For example, the English comparative suffix -er does not attach to stems greater than two syllables in size (smart-er vs. *intelligent-er). Violation of a prosodic subcategorization frame may lead to simple ungrammaticality (e.g. *pretentious-er). In other cases, subcategorization requirements are met by restructuring the prosody of a morpheme’s host. In this talk we consider several case studies in which functional morphemes idiosyncratically impose a particular prosodic structure on their hosts, sometimes with dramatic results.

In Macedonian, preverbal object clitics are typically unstressable ( ‘(s)he saw him’, *). But in the presence of wh-words or sentential negation, such clitics are parsed into the same prosodic word as the verb and may bear stress ( ‘Who saw him?’). In Kaqchikel, a variety of diagnostics indicate that absolutive agreement markers have a different prosodic parse depending on the presence or absence of outer aspect marking (e.g. [xin-b’e] ‘I went’ vs. [in=jwi’] ‘I am intelligent’). The puzzle here is understanding why the prosody of “inner” morphemes (e.g. object clitics) depends on the occurrence of a specific “outer” morpheme (e.g. wh-words).

We propose that these patterns arise from prosodic subcategorization: the “outer” morphemes in question have subcategorization requirements which force re-parsing of their hosts, including any dependent morphemes present in the same structure. We account for this behavior in a novel theory of subcategorization which makes extensive use of prosodic recursion, and which emphasizes the prosodic result of combining a dependent morpheme with its host. We then consider possible extensions of this framework to Chamorro and English, and conclude with the theoretical and methodological implications of our proposal.

This Thursday, February 16th, Elliott Moreton (UNC) will be giving a colloquium talk at 1:30pm in Hum 1, Room 210. His talk is entitled “Emergent positional privilege in blend formation”, and the abstract is included below:

In many languages, sounds in certain “privileged” positions preserve marked structure which is eliminated elsewhere. Does that happen because learners are predisposed towards grammars which protect those positions, or because sounds in those positions are less likely to suffer misperceptive sound change? To test directly for predisposition towards positional faithfulness, a lexical blending task was used to force a choice of which source word to be more unfaithful to. Given source words which could be blended in two ways (e.g., flamingo + mongoose -> “flamingoose” or “flamongoose”), participants preferentially matched the blend that preserved more second-word phonology (“flamongoose”) to a definition which made the second word privileged. The experiments tested for two kinds of faithfulness — to segments and to mainstress location — and in three privileged positions: morpho-semantic heads (vs. non-heads), nouns (vs. verbs), and proper nouns (vs. common nouns). Results from English and, in one experiment, Spanish speakers show both segmental and stress privilege effects in heads, proper nouns, and, to a lesser extent, nouns generally. We interpret these results as evidence for the universal availability of positional-privilege constraints protecting any phonological property of any privileged position.
