요약The labiodental fricative f and interdental fricative θ have an asymmetrical relationship both synchronically and diachronically: θ is rarer than f typologically (UPSID), θ has more variable acoustic cues than f (McGuire and Babel, 2012), θ is more confusable for f than f is for θ (Miller and Nicely, 1955), θ f is common diachronically while f θ is rare or unattested (Honeybone, 2016), and θ is synchronically more volatile across dialects than f (Kjellmer, 1995). But why?The dissertation has six chapters. In chapter 1, we lay out the basic facts about f and θ: their synchronic typology (1.1), their production and perception (1.2), their diachronic behaviour (1.3), and their acquisition (1.4).In chapter 2, we consider two possible explanations for a bias in favour of f and against θ at the level of the individual learner (2.1). One is formal markedness (Trubetzkoy, 1939), encoded as an analytic bias (Moreton, 2008); and one is a channel bias, in line with Evolutionary Phonology (Blevins, 2004). We present a series of artificial language learning experiments aimed at distinguishing the two explanations with a sociolinguistic task combined with a perception test (2.2).In chapter 3, we investigate the mechanism behind channel bias, specifically the asymmetry in confusability between f and θ. First, we run an experiment testing the perception of f and θ by speakers of English and Greek (3.1). Second, we propose the asymmetric overlap hypothesis: that the two fricatives differ in their variance in acoustic space, so θ overlaps with f more than f overlaps with θ (3.2). We discuss the connection between the asymmetric overlap hypothesis and the results of the English-Greek perception experiment, and directions for testing a relationship between acoustic variance and asymmetric misperception.The second half of the dissertation discusses a series of mathematical and computational models to explore how a theory of misperception by individual listeners can scale up into a theory about typology. In Chapter 4, we investigate how misperception of individual tokens can lead to the existence of new I-languages in which all lexical items undergo the same change, following the Neogrammarian hypothesis. We conclude that a theory deriving Neogrammarian regularity from features of the human perceptual system is the most plausible candidate (4.5), and discuss how to incorporate observed cases of lexical diffusion into a theory of phonetically regular misperception (4.6).In Chapter 5, we discuss the incrementation of a change through a speech community stratified by age (5.1), and present a computational model of incrementation in a simulated model population (5.2), showing how the existence of individual new I-languages can lead to a whole community undergoing a sound change.Finally, Chapter 6 lays out a model of phonological typology as a discrete-time stochastic process of random sound changes acting on an inventory of phonemes (6.1). We find that the model derives a relationship between crosslinguistic and within-language frequency (6.2) and offers a diachronic explanation for the clustering of different kinds of 'markedness' discussed in Chapter 2 (6.3). We finish by discussing the assumptions of the model (6.4) and the wider history of the typological distribution of f and θ (6.5).
