The UDCast app recognizes vocal information received through your device’s microphone, and displays captions and sign-language interpretation on your device’s screen. It can also output voice guidance through your device’s earphones.
Before using UDCast for the first time…
(1) At the top UDCast screen, select Test. Then go to the reception area to confirm that your device is working properly.
(2) Before using, you must connect to the Internet and download the desired assistance data (voice guide, captions, and/or sign-language help).
