The LC-STAR US English phonetic lexicon was created within the scope of the LC-STAR project (IST 2001-32216) which was sponsored by the European Commission. The lexicon comprises 102,310 words, distributed over three categories: - a set of 51,119 common word entries. This set is extracted from a corpus of more than 37 million words distributed over 6 different domains (sports/games, news, finance, culture/entertainment, consumer information, personal communications). This was done with the aim of reaching a target for each domain of at least 95% self coverage. In addition to extracting word lists from the corpus, a list of closed set (function) word classes are included in the final word list. - a set of 51,111 proper names (including person names, family names, cities, streets, companies and brand names) divided into 3 domains. Multiple word names such as New_York are kept together in all three domains, and they count as one entry. The 3 domains consist of first and last names (27,244 different entries), place names (15,564 different entries), and organisations (10,751 different entries). - and a list of 6,807 special application words translated from English terms defined by the LC-STAR consortium. This list contains: numbers, letters, abbreviations and specific vocabulary for applications controlled by voice (information retrieval, controlling of consumer devices, etc.). The lexicon is provided in XML format and includes phonetic transcriptions in SAMPA. The database is stored on 1 CD.
