Abstract
Abstract A speech is processed by instantaneously converting sounds of the speech into a sequence of stenographs which are read in the form of first electric signals representative of the stenographs. The first electric signals are further converted into second electric signals representative of words corresponding to the sounds. The second electric signals are successively displayed on a display unit to provide visual displays indicative of the words. The visual displays may be either copied on a sheet by the use of a copying machine or printed on a recording sheet by the use of a printer.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
225 words
A speech processing system comprising stenograph signal producing means for producing a sequence of stenograph signals representative of a sequence of stenographs, respectively, and processing means coupled to said stenograph signal producing means for processing said stenograph signal sequence into an output signal, said stenograph signal producing means comprising: a stationary support with a writing zone and an extension zone being defined relative thereto; a recording medium; drive means for transporting said recording medium relative to said support along a transport direction in sequence through said writing zone and said extension zone, whereby said stenograph sequence is manually written on said recording medium at said writing zone; a movable support; guide means for enabling movement of said movable support over and adjacent to said recording medium along said transport direction in said writing zone; manually operable means for producing a drive signal upon manual operation thereof; said drive means being electrically coupled to said manually operable means for driving said recording medium along said transport direction in response to said drive signal so as to move said recording medium towards said writing zone; and scanning means placed over said recording medium at said extension zone for reading said stenograph sequence on said recording medium to produce a sequence of first electric signals adopted to be provided as said stenograph signal sequence to said processing means.
Claim 2
Dependent Claim
225 words
A speech processing system comprising stenograph signal producing means for producing a sequence of stenograph signals representative of a sequence of stenographs, respectively, and processing means coupled to said stenograph signal producing means for processing said stenograph signal sequence into an output signal, said stenograph signal producing means comprising: a stationary support with a writing zone and an extension zone being defined relative thereto; a recording medium; drive means for transporting said recording medium relative to said support along a transport direction in sequence through said writing zone and said extension zone, whereby said stenograph sequence is manually written on said recording medium at said writing zone; a movable support; guide means for enabling movement of said movable support over and adjacent to said recording medium along said transport direction in said writing zone; manually operable means for producing a drive signal upon manual operation thereof; said drive means being electrically coupled to said manually operable means for driving said recording medium along said transport direction in response to said drive signal so as to move said recording medium towards said writing zone; and scanning means placed over said recording medium at said extension zone for reading said stenograph sequence on said recording medium to produce a sequence of first electric signals adopted to be provided as said stenograph signal sequence to said processing means.
Claim 3
Dependent Claim
126 words
A speech processing system as claimed in claim 1, wherein said processing means comprises: normalizing means coupled to said scanning means for normalizing said first electric signals into a sequence of normalized signals, respectively; pattern storage means for storing a plurality of reference signals representative of patterns corresponding, respectively, to said stenographs; comparing means coupled to the normalizing means and the pattern storage means for comparing each of said normalized signals with the stored plurality of reference signals to detect coincidence between said normalized signals and said reference signals, and to produce an intermediate electric signal corresponding to a reference signal detected by the comparing means to be coincident with a normalized signal; and output means for producing said intermediate electric signal as said output signal.
Claim 4
Dependent Claim
59 words
A speech processing system as claimed in claim 2, wherein said output means comprises: converting means coupled to said comparing means for converting said intermediate electric signal into a word signal indicative of a word specified by said intermediate electric signal; and display means coupled to said converting means for visually displaying said word signal as said output signal.
Claim 5
Dependent Claim
87 words
A speech processing system as claimed in claim 3, wherein said output means comprises: converting means coupled to said comparing means for converting said intermediate electric signal into a word signal indicative of a word specified by said intermediate electric signal; display means coupled to said converting means for visually displaying said word signal to provide a visual display corresponding to said word; and copying means coupled to said display means for copying said visual display on a predetermined copy sheet to visually display said output signal.
Claim 6
Dependent Claim
32 words
A speech processing system as claimed in claim 2, wherein said output means comprises: recording means for recording said intermediate electric signal on a preselected recording medium to produce said output signal.
Claim 7
Dependent Claim
69 words
A speech processing system as claimed in claim 4, wherein said intermediate electric signal is indicative of a phonetic character; said converting means comprising means for supplying said intermediate electric signal to said display means without conversion of said intermediate signal for causing said display means to display said phonetic character as said output signal when said converting means cannot convert said intermediate electric signal into said word signal.
