Koala Chinese Learning uses the built-in system voices on your iPhone／iPad. If read-aloud has no sound, sounds unnatural, or you can't find the recommended voice, follow the steps below to check and download voices.

We recommend the following voices:

• Cantonese: WingChoose the Premium／Enhanced quality version.
• Mandarin: TingtingChoose the Enhanced quality version.
• English: AvaChoose the Premium quality version.

Tap into each language and use the green play button to test the voice.

If it plays correctly, the voice is already installed and ready to use.
