Abstract
Abstract A voice recognition system comprises input means for generating at least one input signal in response to input sounds, a balance line (351a) coupled to the input means for transmitting the input signal from the input means, balance/unbalance converting means (351) for causing the input signal transmitted through the balance line to be transmitted through an unbalance line (351b) and recognizing means for recognizing the input sounds represented by signals on the unbalance line.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
71 words
A voice recognition system, comprising: input means for generating at least one input signal in response to input sounds; a balance line coupled to said input means for transmitting said input signal from said input means; balance/unbalance converting means for causing said input signal transmitted through said balance line to be transmitted through an unbalance line; and recognizing means for recognizing said input sounds represented by signals on said unbalance line.
Claim 2
Dependent Claim
71 words
A voice recognition system, comprising: input means for generating at least one input signal in response to input sounds; a balance line coupled to said input means for transmitting said input signal from said input means; balance/unbalance converting means for causing said input signal transmitted through said balance line to be transmitted through an unbalance line; and recognizing means for recognizing said input sounds represented by signals on said unbalance line.
Claim 3
Dependent Claim
27 words
The voice recognition system of claim 1, said system further including communication means for transmitting an address signal in response to the recognition of said input sounds.
Claim 4
Dependent Claim
28 words
The voice recognition system of claim 2, wherein said communication means includes means for selecting one of a plurality of communication channels for broadcast of said address signal.
Claim 5
Dependent Claim
51 words
The voice recognition system of claim 1, wherein said balance/unbalance converting means includes an operational amplifier, coupled to said balance line for comparing one output signal of said balance line with the other output signal of said balance line to produce an output signal to be transmitted through said unbalance line.
Claim 6
Dependent Claim
52 words
A voice recognition system, comprising: input means for generating at least one input signal in response to input signal; a high-pass filter means coupled to said input means for eliminating low frequency components out of said input signal; and recognizing means coupled to said high-pass filter means for recognizing said input sounds.
Claim 7
Dependent Claim
52 words
A voice recognition system, comprising: input means for generating at least one input signal in response to input signal; a high-pass filter means coupled to said input means for eliminating low frequency components out of said input signal; and recognizing means coupled to said high-pass filter means for recognizing said input sounds.
Claim 8
Dependent Claim
51 words
A voice recognition system, comprising: input means for generating at least one input signal in response to input sounds; signal level control means coupled to said input means for maintaining said input signal at a magnitude; and recognizing means coupled to said signal level control means for recognizing said input sounds.
Claim 9
Dependent Claim
51 words
A voice recognition system, comprising: input means for generating at least one input signal in response to input sounds; signal level control means coupled to said input means for maintaining said input signal at a magnitude; and recognizing means coupled to said signal level control means for recognizing said input sounds.
Claim 10
Dependent Claim
74 words
A voice recognition system, comprising input means for generating at least one input signal in response to input sounds; adjusting means coupled to said input means for adjusting a level of the speech signal from said input means by an adjustment factor; control means for selecting said adjustment factor of said adjusting means on the basis of a level control signal; and recognizing means coupled to said adjusting means1 for recognizing said input sounds.
Claim 11
Dependent Claim
74 words
A voice recognition system, comprising input means for generating at least one input signal in response to input sounds; adjusting means coupled to said input means for adjusting a level of the speech signal from said input means by an adjustment factor; control means for selecting said adjustment factor of said adjusting means on the basis of a level control signal; and recognizing means coupled to said adjusting means1 for recognizing said input sounds.
