QTextTospeech can't found engines

._Miro_.

@jsulm If I do the find command:

sudo find / -name "flite" -type d

I have this output:

/usr/share/doc/flite
/usr/local/include/flite
/usr/include/flite

jsulm

@_Miro_ You need to search for flite library files...

and

 export LD_LIBRARY_PATH=/usr/lib/aarch64-linux-gnu:$LD_LIBRARY_PATH ?

Because, I have the same thing

@_Miro_ said in QTextTospeech can't found engines:

export LD_LIBRARY_PATH=/usr/lib/aarch64-linux-gnu:$LD_LIBRARY_PATH ?

This is not needed for standard locations.
You can also check what happens when plug-ins are loaded. See https://doc.qt.io/qt-6/debug.html QT_DEBUG_PLUGINS

._Miro_.

@jsulm When I load the plugin, only speechd is found in the keys

@_Miro_ said in QTextTospeech can't found engines:

/usr/lib/aarch64-linux-gnu/qt5/plugins/texttospeech

I guess the texttospeech plug-in was built without Flite support?

._Miro_.

@jsulm I don't understand: <<. I assume the texttospeech plugin was built without Flite support? >>

Actually, I can't load the engine for example:

QTextToSpeech *tts = new QTextToSpeech("flite");

return -> Text-to-speech plug-in "flite" is not supported.

jsulm

@_Miro_ You have /usr/lib/aarch64-linux-gnu/qt5/plugins/texttospeech/libqtexttospeech_speechd.so but no /usr/lib/aarch64-linux-gnu/qt5/plugins/texttospeech/libqtexttospeech_flite.so (or whatever the exact lib name is for Flite).

Bonnie

There seems no flite support according to the doc of 5.15 https://doc.qt.io/qt-5/qtspeech-index.html

The module depends on Speech Dispatcher (libspeechd) on the Linux platform.

._Miro_.

@jsulm I finally found my mistake, I'm missing the install

qtspeech5-flite-plugin

Thank you
