SpPhoneConverter

The SpPhoneConverter automation object supports conversion between phoneme symbols and phoneme IDs.

Each language supported by SAPI uses a set of phonemes which represent all the meaningful sounds in that language. Each phoneme has a symbolic representation of its sound, and a numeric ID; in most languages, phoneme IDs are assigned sequentially. Please see the American English Phoneme Representation page for further details.

The following table shows a few English words transcribed into phoneme symbols and phoneme ID's.
