- Computerized Visual Communication (C-VIC)
- A computer-based assistive technology system that enables people with aphasia to communicate by arranging icons and images on screen to form sentences, which can then be translated into spoken or writ…
- Concatenated Speech Synthesis (Concatenative Synthesis, Unit Selection Synthesis)
- A method of producing synthetic speech by connecting pre-recorded segments of human speech, typically diphones (transitions between phonemes) or demi-syllables, to form complete words and sentences. C…
- Concatenative Synthesis (Unit Selection Synthesis)
- A text-to-speech method that generates synthetic speech by concatenating (joining together) pre-recorded segments of human speech. These segments, called units, may be phonemes, diphones, syllables, o…
- Conceptual Model (Mental Model)
