I use the qtspeech for qt5.12 with raspbian buster os , raspberry pi4.
but no sound out put ....
raspberry pi 4 can play video, mp3 , by the web online ,or VLC.. ..
I use the 3.5mm headphone. -
Hi,
What is red warning in the application output console about ?
-
@SGaist yes , the red warning comes out from console of QtCreator when I run the demo.
do I need to adapt the qtspeech with the audio driver of raspbian? if so , how to do that? -
I think it may be need proper audio driver, could anyone tell me what is the audio dirver of qtspeech on the rasperry pi 4?

@stevewu Start the app in a terminal after setting QT_DEBUG_PLUGINS
export QT_DEBUG_PLUGINS=1 ./hello_speak
and post the output here.

@jsulm thank you so much , I do as you said ,run the app in a terminal , and it is OK, sound comes out..
I have another question about the qtspeech----how to change the voice , about male , female ,or age ?
maybe I need to open another topic.... -
