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.
| Words | Phoneme Symbols | Phoneme IDs |
|---|---|---|
| one | w, ah, n | 46, 12, 33 |
| two | t, uw | 41, 44 |
| three | th, r, iy | 42, 38, 28 |
| four | f, ao, r | 24, 13, 38 |
| five | f, ay, v | 24, 16, 45 |
