Microsoft Speech Platform
ISpPhoneticAlphabetConverter
New in SAPI 5.3
Enables applications to convert phonemes from SAPI to the Universal Phone Set (UPS) and from UPS to SAPI.
New applications should use the UPS phone set. To use this interface, applications must call SetLangId to set the language in use, hence the phone set, to which the SAPI phonemes belong. Then it can call the SAPI2UPS and UPS2SAPI methods to perform alphabet conversions.
When to Use
Legacy applications using SAPI phone sets can use this interface to convert existing pronunciations to the UPS phone set. These languages use a SAPI phone set:- English (en-US)
- Chinese (zh-CN)
- German (de-DE)
- Spanish (es-SP)
- French (fr-FR)
- Japanese (ja-JP)
