Please change the pronunciation sound of the words. Previously there was a normal voice, now it sounds like a whisper of a ghost - it is impossible to listen.
Thanks for reaching out!
Wokabulary uses the default system voice of your device. You can find information on how to change it here: https://support.wokabulary.com/article/34-change-voice-for-speech-output
Please check, which voice you have set in your prefences. If you hen still find Wokabulary uses another language, please get back to us at support@wokabulary.com
It can happen that the voice changes after a system update or when you set up a new device. As Anna wrote, Wokabulary relies on the system voices. These can be managed in System Settings. If the voice sounds bad, it usually is because no high quality voice is installed.
I am leaving this request open, so it is easier to find for other users.
