Qt TextToSpeech

The module enables a Qt application to support accessibility features such as text-to-speech, which is useful for end-users who cannot access the application's visual interface. In addition to assistive technologies like screen readers, the most common use case for text-to-speech is when the end-user is driving or operating machinery. In such a scenario, an application can use text-to-speech to read out incoming notifications, or to provide turn-by-turn navigation instructions.

On Linux, the module can use the Speech Dispatcher daemon (libspeechd), or flite. On other platforms, it uses the native system APIs to access the platform-specific text-to-speech engines.

Using the Module

QML API

The QML types of the module are available through the QtTextToSpeech import. To use the types, add the following import statement to your .qml file:

 import QtTextToSpeech

C++ API

Using a Qt module requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including CMake and qmake.

Building with CMake

Use the find_package() command to locate the needed module component in the Qt6 package:

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

For more details, see the Build with CMake overview.

Building with qmake

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
