| summary | In this talk I explore the idea that the functional units of speech are associated with specific phonetic targets that serve as articulatory/acoustic goals. The act of speaking is hypothesized as a process in which the phonetic targets are sequentially approached by an articulatory system that has various intrinsic biophysical constraints. As evidence, it will be demonstrated how surface acoustic forms are generated by target approximation, and how listeners, including infants with no prior phonetic knowledge, can uncover the phonetic targets through unsupervised learning. It will be further demonstrated how multiple layers of information can be encoded in parallel in the speech signal by manipulating the control parameters of the target approximation process. |
