# Dictionary Facilities

DECtalk Software has two pronunciation dictionaries — a large internal (built-in) dictionary and a user-defined dictionary. With the large built-in dictionary, you can easily use many proper names and normally unpronounceable sequences, such as uppercase initials, in applications. With the user dictionary build tool, you can load application-specific words or cultural or language-specific terms into the user dictionary. A sample user-dictionary file is installed with the software.
