Package nzilbb.encoding

Class DISC2CMU

  • All Implemented Interfaces:
    Function<String,​String>, UnaryOperator<String>
    public class DISC2CMU
extends PhonemeTranslator
    Translates CELEX-DISC-encoded transcriptions like tr{nskrIpSVn to CMU-encoded phonemic transcriptions like T R AE N S K R IH P SH AH N.

    The CMU encoding is assumed to use only the phonemes used by the CMU Pronouncing Dictionary: http://www.speech.cs.cmu.edu/cgi-bin/cmudict.

    Thanks to Stefanie Jannedy for this mapping.

    There are differences between the ARPAbet2DISC translation and this one, primarily that this translation is strict; phonemes that are not explicitly present in the phone set are dropped, where ARPAbet2DISC includes extra phonemes, includes some extensions to ARPAbet and DISC, and passes through unknown phonemes unchanged.
