 For some locales, Speech service defines its own phonetic alphabets, which ordinarily map to the [International Phonetic Alphabet (IPA)](https://en.wikipedia.org/wiki/International_Phonetic_Alphabet). The eight locales that support the Microsoft Speech API (SAPI, or `sapi`) are en-US, fr-FR, de-DE, es-ES, ja-JP, zh-CN, zh-HK, and zh-TW. For those eight locales, you set `sapi` or `ipa` as the `alphabet` in [SSML](speech-synthesis-markup.md#use-phonemes-to-improve-pronunciation). 
 
 See the sections in this article for the phonemes that are specific to each locale.
