Voice recognition system having a check scheme for registration of reference data
First Claim
1. A voice recognition system comprising:
- first input means for inputting a voice in the form of pressure waves and converting said voice into an electrical signal;
processing means for processing said electrical signal to produce a voice pattern of a predetermined format;
second input means for inputting an identification information of said voice;
storing means for storing said voice pattern as a reference pattern selectively; and
checking means for checking said identification information to determine whether or not said voice has a predetermined sound element at or near the end thereof, thereby causing said voice pattern to be stored in said storing means if said voice has been found to have no predetermined sound element and then to check said voice pattern to determine whether or not said voice pattern has a corresponding component of said predetermined sound element if said voice has been found to have said predetermined sound element.

Abstract
A voice recognition system includes a microphone for converting a voice in the form of pressure waves into an electrical voice signal and a keyboard for inputting the phonetic spelling of the voice. A check mechanism is connected to the keyboard to determine whether or not the voice has a predetermined sound element, which is difficult to be detected, such as /u/, /i/, /n/ and explosives like /p/, /t/, /k/ and /b/, at or near the end thereof. If the check mechanism has determined the presence of such a predetermined sound element, then it checks the corresponding voice pattern to see whether the corresponding component is present in the pattern or not. If not, a warning may be issued to request reinputting of the voice, thereby insuring the fact that the voice pattern to be registered as a reference voice pattern is always accurate.

12. A voice recognition system comprising:
-
first input means for inputting a voice in the form of pressure waves and converting said voice into an electrical signal; processing means for processing said electrical signal to produce a voice pattern of a predetermined format; second input means for inputting an identification information of said voice; first storing means for storing said voice pattern as a reference pattern selectively; second storing means for storing at least one explosive voice pattern; checking means for checking said identification information to determine whether or not said voice has a voiceless interval near the end thereof and if so to determine whether or not said voice pattern has said voiceless interval near the end thereof; and coupling means for coupling said voice pattern with a corresponding explosive voice pattern stored in said second storing means to define a complete voice pattern before being stored in said first storing means as a reference pattern. - View Dependent Claims (13, 14, 15, 16, 17)
