The first time you open eyeHear, it will request permission to use speech recognition and to access the microphone. Both are required for eyeHear to operate properly. Don't worry, if you don't give eyeHear permission during this step, you can fix that later in the settings app.
Once you've give permission, eyeHear will show a brief explainer, and then you are ready to start captioning!
Captioning a Conversation
To begin captioning a conversation, tap and hold the anywhere on the screen except for the 3 icons. eyeHear will begin listening to what is said and print on screen in the largest possible letters what it thinks it hears. As you hold and eyeHear captions, it will continue to adjust the size of the text to fit on screen. The screen will remain slightly dimmed while eyeHear is captioning. Tap and hold the screen again to begin captioning again.
You can also type responses, or use the keyboard to edit responses for accuracy. Tapping the keyboard icon in the bottom right of the screen will invoke the keyboard mode. Tapping "done" on the keyboard will dismiss the keyboard mode. On iPad and with hardware keyboards, the "done" button may not appear, instead use the return or enter key on the keyboard.
When you begin captioning again, you will notice the previously captioned text disappears. Don't worry! eyeHear remembers that text until the app is quit. Tap the history icon, the clock winding backwards next to the theme button, to see a history of everything that has been said. This history is kept locally until the app is quit. You can send the entire history to another text application by tapping the share icon in the menu bar, or by swiping on a single entry and tapping share. Tapping the trash can icon will erase your entire conversation history.
eyeHear offers two high-contrast themes, light and dark. To switch between them, tap the icon of a T in a rounded box.
