 ## Viseme ID
 
-Viseme ID refers to an integer number that specifies a viseme. We offer 22 different visemes, each depicting the mouth shape for a specific set of phonemes. There's no one-to-one correspondence between visemes and phonemes. Often, several phonemes correspond to a single viseme, because they look the same on the speaker's face when they're produced, such as `s` and `z`. For more specific information, see the table for [mapping phonemes to viseme IDs](#map-phonemes-to-visemes).

 Speech audio output can be accompanied by viseme IDs and `Audio offset`. The `Audio offset` indicates the offset timestamp that represents the start time of each viseme, in ticks (100 nanoseconds).
 
 ### Map phonemes to visemes
 
-Visemes vary by language and locale. Each locale has a set of visemes that correspond to its specific phonemes. The [SSML phonetic alphabets](speech-ssml-phonetic-sets.md) documentation maps viseme IDs to the corresponding International Phonetic Alphabet (IPA) phonemes.

The [SSML phonetic alphabets](speech-ssml-phonetic-sets.md) documentation maps viseme IDs to the corresponding International Phonetic Alphabet (IPA) phonemes. The table below shows a mapping relationship between viseme IDs and mouth positions, listing typical IPA phonemes for each viseme ID.
