The corpus used is the lectures with Chinese as the host language and English as the guest language recorded for a real course offered in National Taiwan University. The techniques reported here have been successfully implemented and tested in a real lecture system now available on-line over the Internet. We also present the approaches of using word fragment as the subword unit for English, and analyse the difficult issues when code-switched lattice-based structures for subword units are used for tasks involving languages of quite different natures.[SDGs]SDG4conference paper10.1109/ASRU.2009.53729012-s2.0-77949367527https://www.scopus.com/inward/record.uri?eid=2-s2.0-77949367527&doi=10.1109%2fASRU.2009.5372901&partnerID=40&md5=7a43a5645068a2ce7cfc90c343a75ba0
