Tabs and modes
| Tab | What it is for |
|---|---|
| Translate | Sign at the camera. Modes: ABC (letters), 123 (digits 0 to 9) and Signs (your taught signs). The top buttons open Conversation mode and show or hide the hand overlay. |
| Teach | Record new signs and delete old ones. |
| Vocabulary | Search, enable, disable and rename taught signs, and import or export sign packs. |
| Settings | The settings above. |
In 123 mode SignVox reads digits instead of letters. ASL uses the same handshape for some digits and letters (0 and O, 2 and V, 6 and W, 9 and F), so you choose the mode instead of SignVox guessing.
