Qt TextToSpeech

The Qt TextToSpeech module enables a Qt application to read out text by using speech synthesis. This is especially useful in scenarios where the end-user cannot access the application's visual interface, for example, when driving or operating machinery. In such setups, the module can be used to read out incoming notifications or to provide turn-by-turn navigation instructions.

The module does not provide a text-to-speech engine itself. Instead, it uses engines native to the operating system. See Qt TextToSpeech 引擎 for more details about this.

使用模塊

QML API

模塊的 QML 類型是可用的透過 QtTextToSpeech 導入。要使用類型，添加以下 import 語句到 .qml 文件：

import QtTextToSpeech

C++ API

使用 Qt 模塊的 C++ API 要求直接 (或透過其它依賴) 鏈接到模塊庫。幾個構建工具對此有專用支持，包括 CMake and qmake .

構建采用 CMake

使用 find_package() 命令定位所需模塊組件在 Qt6 包：

find_package(Qt6 REQUIRED COMPONENTS TextToSpeech)
target_link_libraries(mytarget PRIVATE Qt6::TextToSpeech)

更多細節，見構建采用 CMake 概述。

采用 qmake 構建

要配置采用 qmake 構建模塊，添加模塊作為值為 QT 變量在工程的 .pro 文件：

QT += texttospeech
