 | `ph` | A string containing phones that specify the pronunciation of the word in the `phoneme` element. If the specified string contains unrecognized phones, text-to-speech rejects the entire SSML document and produces none of the speech output specified in the document.<br/><br/>For `ipa`, to stress one syllable by placing stress symbol before this syllable, you need to mark all syllables for the word. Or else, the syllable before this stress symbol will be stressed. For `sapi`, if you want to stress one syllable, you need to place the stress symbol after this syllable, whether or not all syllables of the word are marked.| Required |

 ## Custom lexicon
 
 You can define how single entities (such as company, a medical term, or an emoji) are read in SSML by using the [phoneme](#phoneme-element) and [sub](#sub-element) elements. To define how multiple entities are read, create an XML structured custom lexicon file. Then you upload the custom lexicon XML file and reference it with the SSML `lexicon` element.
