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 Engines for more details about this.
The QML types of the module are available through the
QtTextToSpeech
导入。要使用类型，添加以下 import 语句到 .qml 文件：
import QtTextToSpeech
Using a Qt module's C++ API requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including CMake and qmake .
使用
find_package()
command to locate the needed module component in the
Qt6
包：
find_package(Qt6 REQUIRED COMPONENTS TextToSpeech)
target_link_libraries(mytarget PRIVATE Qt6::TextToSpeech)
更多细节，见 构建采用 CMake 概述。
To configure the module for building with qmake, add the module as a value of the
QT
variable in the project's .pro file:
QT += texttospeech
