Fields
`customPronunciations`	`object (CustomPronunciations)` 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.
Union field `input_source`. The input source, which is either plain text or SSML. `input_source` can be only one of the following:
`text`	`string` The raw text to be synthesized.
`markup`	`string` Markup for HD voices specifically. This field may not be used with any other voices.
`ssml`	`string` The SSML document to be synthesized. The SSML document must be valid and well-formed. Otherwise the RPC will fail and return `google.rpc.Code.INVALID_ARGUMENT`. For more information, see SSML.
`multiSpeakerMarkup`	`object (MultiSpeakerMarkup)` The multi-speaker input to be synthesized. Only applicable for multi-speaker synthesis.
`prompt`	`string` This system instruction is supported only for controllable/promptable voice models. If this system instruction is used, we pass the unedited text to Gemini-TTS. Otherwise, a default system instruction is used. AI Studio calls this system instruction, Style Instructions.
