Abstract: 196,273. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Weinberger, J.). April 17, 1922, [Convention date]. Duplex signalling; eliminating undesired signals; tone or group frequency tuning-arrangements.-Two or more signals received upon the same or different aerials are conveyed to a distant collecting station over a single line. Signals from the aerial system 1 are passed into detecting-sets 2, 3 and emerge as two audible tone-frequencies say of 700 and 1200 cycles respectively. The lower frequency is passed through a known filter circuit comprising inductances 20, 21, 22 in series and capacities 16, 17, 18 in shunt, the system having a cut-off frequency of preferably 850 so as to allow for slight variations in the lower signal frequency. The higher frequency is passed through a high-pass filter 23 - - 27 which cuts out all frequencies below 1,050 cycles. The two frequencies are then passed through transformers 6, 14 to the common line 5. Similar filter circuits may be arranged at the far end in asscciation with the phones 7, 8. In this way each signal is kept distinct, moderate fluctuations of wave-length occurring at the transmitter do not seriously affect the loudness of the signal, and the effect of atmospherics is rendered. A similar arrangement may be used to transmit more than two signals simultaneously, suitable band filters being used in place of the high and low pass circuits shown.

Title: Apparatus for the analysis of waveforms
Inventor: WRIGHT ESMOND PHILIP GOODWIN
IPC: G10L25/09
Filed: 1964-03-06
Abstract: 1,012,765. Automatic speech recognition; electric selective signalling. STANDARD TELEPHONES & CABLES Ltd. March 6, 1964, No. 9638/64. Headings G4H and G4R. [Also in Division G1] Apparatus for analyzing waveforms, e.g. for speech recognition comprises means for detecting reversals of polarity in the waveform, the periods between reversals being measured by counting pulses produced by a time scale generator. In Fig. 1, the zero-crossings of the waveform are used to obtained a succession of time periods. In Fig. 2 the points at which the waveform crosses positive and negative threshold levels are used to eliminate spurious reversals due to noise. The time scale, Fig. 3, consists of a series of pulses initially crowded together but becoming more widely spaced. This enables the same degree of accuracy to be obtained for short or long periods. The alternate positive and negative periods are arranged to pass pulses to separate counters. Over a given interval the number of periods of the same length, i.e. producing the same count, is counted in a threshold counter which gives an output if the threshold is exceeded. The outputs of these channel counters is an analysis of the input waveform and may be used to recognize the components of the input word signal. In the system of Fig. 8, the speech input is normalized at 87 and then separated into components as follows: circuit 88 indicates whether the sound is voiced or not; circuits 89 and 90 extract the first and second formants; circuit 91 extracts the fundamental frequency; circuits 92, 93 extract frequency groups associated with unvoiced sounds and circuit 94 extracts a consonant signal. In addition a threshold circuit 95 indicates the presence of a speech signal and circuit 96 indicates, from this, that the word has ended. The fundamental frequency is used in circuit 99 to provide control signals for the measuring process described above and also segmentation signals which serve to sample the measurements obtained at appropriate instants. Circuit 97 analyses the voiced sounds (vowels) using the first formant and the second if necessary. Circuit 98 analyses the corresponding unvoiced sounds. Both these circuits use the counting system described above. The vowel, for example, appearing as a series of short " part vowels " which are counted and stored, being read out when a predetermined count is reached to phoneme recognition circuit 100. This circuit, which also receives signals from circuits 88 and 94, consists of an array of resistors, Fig. 10, between vertical lines connected to the part vowel stores D1, D2 &c. and horizontal lines connected to a threshold comparator. One of the horizontal lines will receive a higher signal and this will identify the sound. Successive phonemes pass to circuit 101 to identify the word when the end of word signal appears from circuit 96.
