Limited-Domain Speech-to-Speech Translation between English and Pashto

   Abstract

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.
