ECTistener software created and developed by EyeComTec (www.eyecomtec.com) is intended to analyze sound signals from any microphone. Depending on the length and volume of the signal ECTlistener emulates key strokes and sends control codes to the receiving software.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 and many other sounds. This allows them to communicate with their relatives friends service or medical staff.Nowadays there are many technical solutions that allow users to generate key strokes with different sounds or inhalation or exhalation of air. However all these solutions require special equipment and are not available for everyone at a reasonable price. Simultaneously EyeComTec are developing ECTlistener as an easy comfortable to use and affordable alternative for those solutions.To start the program the user needs only a personal computer equipped with a microphone which are freely available in any electronic or computer shop. ECTlistener can even work on very old personal computers with low productivity due to the programs low system requirements. Furthermore fast export or import of all settings the small size of the program and the ability to work without any installation allows the user to execute ECTlistener from any removable device for example flash card external hard drive etc.The program is really customizable and has a user-friendly interface. Initial settings take only few minutes to operate and program is ready to work! ECTlistener is free for any private use contains no advertising and supports many languages.
