The speech of non-native (L2) speakers of a language contains phonological rules that differentiate them from native speakers. These phonological rules characterize or distinguish accents in an L2. The Shibboleth program creates combinatorial rule-sets to describe the phonological pattern of these accents and classifies L2 speakers into their native language. The training and classification is done in Shibboleth by support vector machines using a Gaussian radial basis kernel. In one experiment run using Shibboleth, the program correctly identified the native language (L1) of a speaker of unknown origin 42% of the time when there were six possible L1s in which …

The field of authorship determination, previously largely falling under the umbrella of literary analysis but recently becoming a large subfield of forensic linguistics, has grown substantially over the last two decades. As its body of research and its record of successful forensic application continue to grow, this growth is paralleled by the demand for its application. However, methods which have undergone rigorous testing to show their reliability and replicability, allowing them to meet the strict Daubert criteria put forth by the US court system, have not truly been established. In this study, I set out to investigate how a list …
