An AAC board should make meaningful communication easier, not ask someone to learn a caregiver's filing system. TapTalk works best when the communicator helps choose the words, images, placement, and voice that feel useful.
Begin with frequent, powerful language
Include words and phrases for needs, choices, people, places, feelings, yes, no, stop, more, and help. Add personal interests so the board supports conversation, not only requests.
Keep locations predictable
Group related tiles, but avoid moving familiar words without a good reason. Test tile size, contrast, volume, and the number of choices with the communicator in real settings.
Model without taking control
Use the board alongside speech and give enough time for a response. Do not demand a specific mode of communication or speak over the person. A speech-language professional can help with individual access and communication needs.
