The Pronunciation lexicon of British place names, surnames and first names was produced by the University of Poitiers (France) through a funding from ELRA in the framework of the European Commission project LRsP&P (Language Resources Production & Packaging - LE4-8335). This lexicon is an SGML-encoded database of British proper names. All entries belong to one or several of the following categories: place-names (a quasi-exhaustive list of toponyms from England, Scotland and Wales), and surnames or first names (a selection of names based on an extensive survey of bibliographic sources in the field of British onomastics combined with lists compiled by the author of this lexicon).

The database is composed of 160,000 entries, breaking down as follows:

Place-names Number of entries Number of transcriptions
England 31,635 44,969
