The program was created for disabled people (paralyzed or those with extremely reduced mobility) and works in conjunction with other programs (e.g. ECTkeyboard symbol matrix). By using a personal computer with a microphone and both ECTlistener and ECTkeyboard, patients can type text letter-by-letter by using individualized vocal prompts such as moans, loud breathing, sniffing, blowing and many other sounds. This allows them to communicate!
