additionalLanguageCodes property
Additional codes for languages available for the specified voice in addition to its default language.
For example, the default language for Aditi is Indian English (en-IN)
because it was first used for that language. Since Aditi is bilingual and
fluent in both Indian English and Hindi, this parameter would show the code
hi-IN
.
