To acquire one's native phonological system, language-specific phonological categories and relationships must be extracted from the input. The acquisition of the categories and relationships has each in its own right been the focus of intense research. However, it is remarkable that research on the acquisition of categories and the relations between them(More)
We summarize the accomplishments of a multidisciplinary workshop exploring the computational and scientific issues surrounding zero resource (unsupervised) speech technologies and related models of early language acquisition. Centered around the tasks of pho-netic and lexical discovery, we consider unified evaluation metrics, present two new approaches for(More)
The basic representational hypothesis in phonology is that segments are coded using a universal set of discrete features. We propose a method for quantitatively measuring how well such features align with arbitrary segment representations. We assess artic-ulatory, spectral, and phonotactic representations of English consonants. Our procedure constructs a(More)
In this paper we introduce an inductive bias for language acquisition under a view where learning of the various levels of linguistic structure takes place interactively. The bias encourages the learner to choose sound systems that lead to more " semantically coherent " lexicons. We quantify this coherence using an intrinsic and unsupervised measure of(More)
We investigate the idea that the languages of the world have developed coherent sound systems in which having one sound increases or decreases the chances of having certain other sounds, depending on shared properties of those sounds. We investigate the geometries of sound systems that are defined by the inherent properties of sounds. We document three(More)
