Optional. The pronunciation customizations are applied to the input. If
this is set, the input is synthesized using the given pronunciation
customizations.

The initial support is for en-us, with plans to expand to other locales in
the future. Instant Clone voices aren't supported.

In order to customize the pronunciation of a phrase, there must be an exact
match of the phrase in the input types. If using SSML, the phrase must not
be inside a phoneme tag.
