Weave Chat AAC offers a large variety of verbs (green), pronouns (yellow), questions (purple), nouns (tan/orange), adjectives (blue), and conversational words (pink). All color choices were made based on the Fitzgerald Key and new vocabulary is added weekly. Users can add their own custom images and categories in Settings —> Manage Custom Images. In addition, users can add their own custom phrases that can easily be accessed from their board; to add phrases, go to Settings —> Manage Phrases. Users can select a synthetic voice (dependent on their device settings) from Settings —> Change Voice Settings - here you can select your voice, vocal pitch, and rate of speech. Image and text size can be personalized from Settings —> Change Image & Text Size (select from default - small, medium, and large). Settings —> Configure Image Keyboard allows the user to turn on/off features that allow for the category text to be read aloud (synthetic voice for categories), to keep the user in the category after a image has been selected (stay on category after image selection), and disable the speech output for individual words so that it only reads aloud when the white text screen is touched (synthetic voice disabled for individual words). The AAC board can be modified in Settings —> Manage Board Builder. Here, the user can select from the default board (you must make a copy to edit it - to do this select “Add new keyboard” and then select “Hide Images” for Type of Keyboard); grid position boards (ranging in size from 1x2 - 7x15 rows/columns); and Board Builder (gives you the option to build a board from scratch). All boards are completely editable and all custom images and categories can be used from all boards. Lastly, Manage Pin Configuration allows the user to set a pin over all (or just some) aspects of customization to lock down features as needed.
