Of course! Semper uses your phone's built-in text-to-speech (TTS) engine to read items to you.
To enable this:
1. Make sure you have the latest version of Google TTS installed - https://play.google.com/store/apps/details?id=com.google.android.tts
2. Set it to default in your phone's settings > language and input > text-to-speech
3. In the Semper app, navigate to the add-ons tab (the 3rd tab)
4. Install the "Review & Speech" add-on and set review screens to enabled
You should now see review screens with a small audio icon after every puzzle you solve. Just tap the audio icon to hear how the word is pronounced.
If the language you're learning does not appear on your phone you could search for a different TTS app which provides TTS for that language, as soon as it is installed Semper will start using it and read items in your favorite language.
