Telephone dialling system for the blind
An almost blind client, unable to read even large telephone buttons, required a simple dialling system with pre-programmed numbers.
The telephone was electrically connected to a commercial pre-programmable speech-recording device mounted in a metal box which houses the control electronics, a speaker and microphone and has eight selector buttons. When the client selects a button the unit speaks the name of the person to be called. Once the correct person is found, the telephone handset is lifted and the button pressed a second time. The unit then speaks the name again and automatically dials the required number.
The client is now able to use the telephone to contact eight frequently called/important numbers without assistance.
