Indonesian and English captions, translated as the video plays

Wuai is a free app for Windows and Android that captions the videos you watch and translates the captions in real time, on your device. These screenshots show it turning Indonesian speech into English captions and English speech into Indonesian captions, on Windows and on Android.

Indonesian captions as a Indonesian video plays

Recorded in Wuai on Windows with Plus, the free speech model, not sped up: Indonesian speech with Indonesian captions, such as “Tapi kalau misalnya kamu keluar dari Jawa”, and no translation. Each line comes a moment after it is said; turn on Wait for captions and the video waits for it. Video: WIKITONGUES- Nila speaking Indonesian by Wikitongues, CC BY 3.0, on Wikimedia Commons.

A Indonesian video with English captions

Wuai on Windows: a Indonesian video with English captions, “And Jakarta is a very metropolitan city.” over “Dan Jakarta adalah kota”.
