The majority of the links on this page point to external websites included in the large list of many hundreds of links from Joaquim Llisterri (Autonomous University of Barcelona) or other collections of links contained therein.
The links on this page here were hand-selected to be maximally useful as a supplement a graduate-level course in linguistic phonetics where English is the medium of instruction. The links are grouped by the different areas in which they typically arise in such a context.
The overall goal is to be a well-organized portal to only the most important resources, not to comprehensively index the contents of each site. As such, there is generally only one link per domain (at the highest level of the website relevant for phonetics).
Also, due to the nature of YouTube and Wikipedia, nothing from those sites is linked here. However, a large body of excellent material can be found there (e.g. videos of the cardinal vowels and laryngeal anatomy on YouTube).
Mixed in with the external links are a handful of PDFs and webpages developed and hosted locally at Indiana University. PDFs in this category are marked as [Internal, PDF]. Likewise, webpages that pop up in a separate window are marked with [Internal, Pop-up].
