Class DISC2IPA

  • All Implemented Interfaces:
    Function<String,​String>, UnaryOperator<String>
    public class DISC2IPA
extends PhonemeTranslator
    Translates CELEX-DISC-encoded transcriptions like tr{nskrIpS@n to IPA-encoded phonemic transcriptions using Unicode characters like tɹænskɹɪpʃən.

    This supports straight round-trip conversion with IPA symbols used by IPA2DISC. The 1-to-1 mappings are:
