Charlie's Personalized AAC System

Charlie Rivera’s personalized AAC system was the evolving communication setup used by Charlie Rivera as fatigue, aphasia, and reduced biological speech made spoken communication increasingly unreliable. He first used TD Snap and later transitioned to Grid 3 at a different stage of his life.

Overview

The system combined robust AAC software, Charlie’s English and Spanish vocabulary, a synthetic voice created from his own speech, and recorded message-bank audio. Its configuration changed over time rather than remaining tied to one software platform or one stage of disability.

Charlie used the system alongside biological speech, sign language, gesture, and writing. AAC became his primary reliable voice in later life but did not replace those other methods.

Components and Configuration

Charlie’s earlier electronic setup used TD Snap on a portable iOS device. It supported stored phrases, symbol- and text-based communication, and synthesized speech.

He later moved to Grid 3 on a Windows-based system. The transition allowed more extensive customization as his communication and access needs changed.

Vocabulary and Language

The vocabulary included English and Spanish, spelling access, common medical and care language, names of loved ones, boundaries, music terminology, affectionate language, profanity, jokes, and phrases Charlie selected himself. Logan Weston and Ava Keller helped organize the selected vocabulary, but Charlie remained the author of what the system said.

Stored phrases preserved Charlie’s own register rather than translating his needs into generic clinical wording. “Let me nap, chaos goblins” became a family favorite because it communicated a serious boundary in the humorous language Charlie actually used.

Voice and Output

While Charlie could still sustain the necessary speech, he completed a standardized voice-banking recording script. Those recordings were used to create a synthetic voice that approximated his earlier speaking voice for flexible text-to-speech output.

Archival recordings served a different purpose. Selected clips of Charlie’s actual speech, signature phrases, and laughter became message-banked audio that could be played without requiring the synthetic voice to reproduce their timing or emotional texture. His custom laugh messages included several distinct recordings rather than one generic laugh.

Communication Use

Charlie used the system during family conversations, medical care, public events, travel, creative work, and periods when speaking cost more energy than he could sustain. Early use supplemented speech during flares. Later use carried most conversation, with occasional biological words or whispers used when he chose and could manage them.

Acquisition, Assessment, and Training

Ava and Logan helped Charlie trial, organize, and adapt the system as chosen family. Charlie was never Ava’s formal patient, and the work did not occur through a clinical treatment relationship. Ava contributed AAC expertise, Logan contributed detailed knowledge of Charlie’s health and physical access, and Charlie made the decisions about language, voice, humor, and use.

History and Replacement

TD Snap belonged to the earlier stage of Charlie’s AAC use. Grid 3 became the later system as he needed deeper customization. The later system retained his selected vocabulary, personalized synthetic voice, and message-banked recordings.

Associated People and Organizations

Ava Keller

Ava contributed AAC knowledge and helped organize vocabulary, voice banking, message banking, and the later access transition. Her role was an informal chosen-family collaboration, not a clinician-patient relationship.

Logan Weston

Logan contributed detailed knowledge of Charlie’s health and communication needs and worked with Ava and Charlie on system changes.
