Abstract: Speech synthesizing apparatus is provided in which different sounds are required for a plurality of channels. The channels are polled in turn on a cyclic scanning basis, the scan for each channel occupying a channel sampling period during which an instantaneous value is generated for the amplitude of a voiced sound component. Values representing instantaneous amplitudes of each of a plurality of unvoiced sounds are separately generated in turn during the period occupied by the scanning of all the channels and these values are stored. A selected one of the unvoiced sound values is extracted from the store as required for a particular channel during the sampling period for that channel, so that an updated value for the unvoiced sound is available on each occasion that that particular channel is sampled. The voiced and unvoiced sound values are then combined during the appropriate sampling periods. The required sound combinations are specified by parameters expressed in digital form for each channel separately.

Abstract: Speech synthesizing apparatus is provided using digital coded values specifying parameters of a sound to be reproduced. The apparatus has a voiced sound generator using digital values specified by input parameters to represent three formant waveforms respectively which are sampled at substantially constant intervals, the parameters each expressing in relation to the sampling interval the frequency of the formant concerned. At each sampling, the input parameters are arranged to derive for each formant waveform respectively a value representative of the instantaneous amplitude of that waveform in relation to the others, the three values obtained then being combined to produce a resultant value representing an instantaneous amplitude output of a voiced sound component waveform. This output waveform is subjected to modification by attenuation and the addition, if required, of an unvoiced sound component before being passed through an analogue converter to a sound reproducing transducer.

Abstract: Sound Analyzing Apparatus is described for extracting from a speech signal certain basic formant waveforms present in the signal and then examining the formant waveforms to identify the frequency components of the waveforms, using a histogram format in a digital processor. This frequency analysis is accomplished by rectifying the formant waveform, detecting the occurrence of peaks in the resultant waveform and evaluating the time intervals between successive peaks. The apparatus is also biased to reject as invalid those time intervals when peaks of less than a predetermined magnitude occur. Since the formant waveform is typically a succession of damped waves, the frequencies detected are classified into ranges and a running average of the allocation of the frequency components over the ranges is developed over successive sampling periods in order to provide a histogram output illustrative of the final analysis.
