# XSpeechSynthesizerInstalledVoicesCallback

A função de retorno de chamada implementada pelo cliente que recebe informações sobre uma voz quando [XSpeechSynthesizerEnumerateInstalledVoices](/pt-BR/reference/system/xspeechsynthesizer/functions/xspeechsynthesizerenumerateinstalledvoices) é chamada.

## Sintaxe

```cpp theme={null}
bool XSpeechSynthesizerInstalledVoicesCallback(  
         const XSpeechSynthesizerVoiceInformation* information,  
         void* context  
)  
```

### Parâmetros

*information*   \_In\_\
Tipo: [XSpeechSynthesizerVoiceInformation\*](/pt-BR/reference/system/xspeechsynthesizer/structs/xspeechsynthesizervoiceinformation)

Um ponteiro para uma estrutura [XSpeechSynthesizerVoiceInformation](/pt-BR/reference/system/xspeechsynthesizer/structs/xspeechsynthesizervoiceinformation) que contém os detalhes da voz enumerada no momento.

*context*   \_In\_\
Tipo: void\*

O ponteiro de contexto que foi fornecido na chamada inicial para [XSpeechSynthesizerEnumerateInstalledVoices](/pt-BR/reference/system/xspeechsynthesizer/functions/xspeechsynthesizerenumerateinstalledvoices).

### Valor retornado

Tipo: bool

Retorna **true** se [XSpeechSynthesizerEnumerateInstalledVoices](/pt-BR/reference/system/xspeechsynthesizer/functions/xspeechsynthesizerenumerateinstalledvoices) deve continuar enumerando e **false** se [XSpeechSynthesizerEnumerateInstalledVoices](/pt-BR/reference/system/xspeechsynthesizer/functions/xspeechsynthesizerenumerateinstalledvoices) deve parar de enumerar.

## Comentários

* Enquanto a função **XSpeechSynthesizerInstalledVoicesCallback** retornar **true**, a função de retorno de chamada **XSpeechSynthesizerInstalledVoicesCallback** será chamada por [XSpeechSynthesizerEnumerateInstalledVoices](/pt-BR/reference/system/xspeechsynthesizer/functions/xspeechsynthesizerenumerateinstalledvoices) uma vez para cada mecanismo de síntese de fala instalado, ou *voz*. Se a função **XSpeechSynthesizerInstalledVoicesCallback** retornar **false**, **XSpeechSynthesizerEnumerateInstalledVoices** interromperá a enumeração das vozes instaladas restantes.

* Para identificar e exibir informações sobre cada voz instalada no dispositivo atual, use os dados fornecidos pela estrutura [XSpeechSynthesizerVoiceInformation](/pt-BR/reference/system/xspeechsynthesizer/structs/xspeechsynthesizervoiceinformation) em *information*.

* Para obter um exemplo que demonstra como usar a função de retorno de chamada **XSpeechSynthesizerInstalledVoicesCallback**, consulte [XSpeechSynthesizerEnumerateInstalledVoices](/pt-BR/reference/system/xspeechsynthesizer/functions/xspeechsynthesizerenumerateinstalledvoices).
