Chinese audio
Audio is Mandarin. A version with recorded female and male voices is being prepared. After release, voice and speed can be chosen in Pronunciation Settings. The Taiwan row shows Taiwan Mandarin traditional characters and zhuyin; playback reads the simplified Mandarin text above.
If playback fails, check the device volume and pronunciation settings, and tell us which word or sentence is affected.
Availability
The apps are being prepared for the App Store. Check the listings and in-app screens for features and prices after release.
