Abstract
Abstract A voice recognition interval scoring system comprises a pitch extractor (3) for extracting at least a fundamental pitch of the wave of a voice or a musical sound, a processor (CPU) for transducing pitch data generated by the pitch extractor into a musical interval, a memory (4) for storing the result of the processor, and a note indicator (5) with a musical sound generator (6) for visually or audibly expressing the content of the memory.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
74 words
A voice recognition interval scoring system characterised by comprising: pitch extracting means (3) for extracting at least the fundamental pitch of the wave of a voice or a musical sound; transducing means (CPU) for transducing pitch data generated by said pitch extracting means into a musical interval; memory means (4) for storing the result of said transducing means; and interval reproducing means (5,6) for visually or audibly expressing the content of said memory means.
Claim 2
Dependent Claim
74 words
A voice recognition interval scoring system characterised by comprising: pitch extracting means (3) for extracting at least the fundamental pitch of the wave of a voice or a musical sound; transducing means (CPU) for transducing pitch data generated by said pitch extracting means into a musical interval; memory means (4) for storing the result of said transducing means; and interval reproducing means (5,6) for visually or audibly expressing the content of said memory means.
Claim 3
Dependent Claim
32 words
A voice recognition interval scoring system as claimed in claim 1 characterised in that said interval reproducing means includes a musical sound generator (6) for producing a plurality of musical sound waves.
Claim 4
Dependent Claim
29 words
A voice recognition interval scoring system as claimed in claim 1 or 2 characterised by further comprising correcting means (7) for correcting interval data stored in said memory means.
Claim 5
Dependent Claim
40 words
A voice recognition interval scoring system as claimed in claim 3 characterised in that said correcting means includes a switch (94,95,96,97) for selecting an address of said memory means and a switch for changing the interval of the address selected.
Claim 6
Dependent Claim
39 words
A voice recognition interval scoring system as claimed in any preceding claim characterised by comprising an external switch for setting reproduction at an octave-shift action when the content of said memory means is produced by said interval reproducing means.
Claim 7
Dependent Claim
45 words
A voice recognition interval scoring system as claimed in any preceding claim characterised by including a tempo generator (8), said pitch extracting means operating in response to a tempo signal from said tempo generator and being inhibited until said voice or musical sound is applied.
Claim 8
Dependent Claim
126 words
A voice recognition interval scoring system as claimed in any preceding claim characterised in that said pitch extracting means comprises an inverting circuit (32) for inverting the wave of said voice or said musical sound, a first peak hold circuit (33), a second peak hold circuit (34) and a flip-flop (35) controlled by said first peak hold circuit and said second peak hold circuit, said first peak hold circuit in operation detecting a positive peak of said wave of said voice or said musical sound, said second peak hold circuit in operation detecting a positive peak of the output of said inverting circuit so that a period of said voice or said musical sound is detected by measuring the period of the output of said flip-flop.
