Abstract: 5Provided is a voice encoding device which can accurately encode a spectrum shape of a signal having a strong tonality such as a vowel. The device includes: a sub-band constituting unit (151) which divides a first layer error conversion coefficient to be encoded10 into M sub-bands so as to generate M sub-band conversion coefficients; a shape vector encoding unit (152) which performs encoding on each of the M sub-band conversion coefficient so as to obtain M shape encoded information and calculates a target gain of each of the M sub-band conversion coefficients: a gain vector forming unit (153) which forms one gain vector by using M target gains; a gain vector encoding unit (154) which encodes the gain vector so as to obtain gain encoded information; and a multiplexing section unit (155) which multiplexes the shape encoded information with the gain encoded information.20Figure 2

Abstract: OBJECT PROVIDED IS A SPEECH ENCODING DEVICE WHICH CAN ACCURATELY ENCODE A SPECTRUM SHAPE OF A SIGNAL HAVING A STRONG TONALITY SUCH AS A VOWEL. OVERCOMING MEANS A SUBBAND FORMING SECTION (151) DIVIDES A FIRST LAYER ERROR CONVERSION COEFFICIENT WHICH IS THE TARGET TO BE ENCODED, INTO M SUB-BANDS SO AS TO GENERATE M SUB-BAND CONVERSION COEFFICIENTS; A SHAPE VECTOR ENCODING SECTION (152) PERFORMS ENCODING ON EACH OF THE M SUB-BAND CONVERSION COEFFICIENT SO AS TO AQUIRE M SHAPE ENCODED INFORMATION AND CALCULATES A TARGET GAIN OF EACH OF THE M SUB-BAND CONVERSION COEFFICIENTS; A GAIN VECTOR FORMING SECTION (153) FORMS ONE GAIN VECTOR BY USING M TARGET GAINS; A GAIN VECTOR ENCODING SECTION (154) ENCODES THE GAIN VECTOR SO AS TO AQUIRE GAIN ENCODED INFORMATION; AND A MULTIPLEXING SECTION (155) MULTIPLEXES THE SHAPE ENCODED INFORMATION WITH THE GAIN ENCODED INFORMATION.
