Abstract: 1282295 Vocoder excitation detection INTERNATIONAL BUSINESS MACHINES CORP 29 Oct 1969 [29 Oct 1968] 52863/69 Heading H4R In a vocoder excitation function generator a sequence of excitation function signals, representing the magnitudes of a predetermined number of successive excitation function periods, is compared with a number of predetermined configurations, representing alternative variations in the excitation function period over the same predetermined number of periods, in order to generate a coded signal representing the predetermined configuration having the best match. The coded signal is transmitted, together with a starting value of pitch period at the commencement of a voiced sound, to enable selection of appropriate values of excitation function at the vocoder synthesizer. As described, Fig. 3, groups of six successive pitch periods are treated and compared with five alternative patterns of variation, a possible set being shown in Fig. 4 where P0 is the final value obtained with the previous configuration. The initial value P0, determined as the final value of the previous configuration, or the initial value of pitch period at the start of a voiced sound is fed from a gate circuit 6 via "and" gate 75 and "or" gate 74 to register 80. The value is then fed to register 82 where it serves as a basic value for the generation, in registers 83 to 87, of the possible values of pitch period in the predetermined configuration. The succeeding six values of pitch period are fed successively into subtraction device 8 to be compared with each successive value of each predetermined configuration and the results for each configuration fed into respective accumulators A1 to A5. After the six values of pitch period have been fed into the subtraction device 8 and the differences from the predetermined configuration stored in accumulators A1 to A5 the detector circuit 69 determines which accumulator contains the smallest value and indicates at its output the number of the predetermined configuration closest to the incoming configuration. This number is transmitted on line 71. A detector circuit is described for determining the minimum accumulator value in which the binary values stored in the accumulators are inspected and progressively shifted towards and out of the highest order bit position until one accumulator contains all zero's, that accumulator containing the lowest value and having its number transmitted as the number of the closest configuration.
