The SRI CAST project has developed a prototype system for
near-real-time, spontaneous, bidirectional translation between spoken
American English and Pashto within the domain of doctor-patient
interaction. The final system is intended to run on a handheld device
(PDA), with its attendant memory and speed limitations. Pashto, an
Indo-Iranian language spoken in Afghanistan and western Pakistan,
presents many challenges to both data-intensive and knowledge-based
approaches to automatic translation because of its lack of language
resources, including both data and expert knowledge. Our principal
translation approach is knowledge-based, employing a bidirectional
parser/generator and quasi-logical forms, along the lines of previous
SRI projects such as the Spoken Language Translator. When this "deep"
translation approach fails we back off to two shallower methods: a
statistical translator and a simple word-by-word translator.
John Fry earned a BA in Linguistics and Computer Science from UCLA and a Ph.D. in Linguistics, with a minor in Computer Science, from Stanford University. His research interests are in the area of computer processing of spoken and written natural language.
