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 …

Due to the limits of Arizona's secondary education system, English teachers often have to teach Standard English without regard for students' dialects and home languages.

I also present some ways that educators can be …

The more tools investigators have to assist them, the better. 911 calls are often the least influenced form of linguistic evidence, in the sense that the caller has not yet been influenced by lawyers, law enforcement, etc.. This paper analyzes the reliability of using the Considering Offender Probability in Statements (COPS) scale and concordance program to evaluate veracity in 911 homicide calls. To do this, six 911 homicide calls from Mesa, Arizona were transcribed, evaluated based on the COPS scale, and put through a concordance program. The results showed …
