Title: Method and device for conducting programming of computer by audible command
Inventor: RONARUDO ERU KORII
IPC: G10L15/26
Filed: 1991-07-30
Abstract: PURPOSE: To program a computer by an instruction extracted from a voice command vocalized by a user. CONSTITUTION: An instruction is inputted by a voice from a microphone 6. Both of hardware and software have two modes, i.e., a training mode and an execution mode. In the training mode, the hardware is teached by a user so as to relate a displayed specific instruction to a user's voice command. When the digital display of a received voice coinsides with one of stored voice commands in the execution mode, the software starts operation corresponding to the coincident command and sends the started operation to an output circuit in order to execute it. The output circuit translates the corresponding operation recalled by the software to a suitable analog, digital or hybrid signal at timing suitable to the invented application to execute a requested function.
