Filed:

Jun 13, 1979

Appl. No.:

6/048238

Inventors:

Brian L. Scott - Denton TX
Lee H. Hardesty - Denton TX

Assignee:

Scott Instruments Company - Denton TX

International Classification:

G10L 100

US Classification:

179 1SC

Abstract:

Voice pitch is detected by passing a speech signal from a microphone 10 through a filter array 20 to a summing amplifier 22. The summing amplifier 22 provides a composite signal of the acoustic components of the speech signal and this composite signal is input to a multiplier 26 and from the multiplier 26 to a multiplier 36 having an output connected to a comparator 42. The comparator 42 compares the output of the multiplier 36 with a hysteresis signal, then provides an output to a phase locked loop 46. The phase locked loop 46 provides a first voltage output in analog form to a bar graph display 50 and provides a square wave output that is applied to a frequency-to-voltage converter 52 for driving a digital display 54.

Inventors:

Brian L. Scott - Denton TX

Assignee:

Scott Instruments Company - Denton TX

International Classification:

G09B 2100

US Classification:

434114

Abstract:

A speech signal is input to a microphone (10) and applied through a signal compressor (14) to a filter array (18) consisting of a high pass channel (20), a midfrequency channel (22) and a low pass channel (24). The outputs of the filter array (18) are precision rectified in rectifiers (28), (36) and (46). The rectified signals are applied to voltage controlled power drivers (54) and (56), where the output of the midfrequency channel (22) and the low frequency channel (24) are applied to the power driver (54) and the output of the high frequency channel (20) and the low frequency channel (24) are applied to the power driver (56). The power driver (54) drives vibrators (58) and (60) and the output of the power driver (56) drives a vibrator (62). To drive the vibrators (58) and (60), a random frequency signal at the output of a one shot multivibrator (38) is amplitude modulated by the output of the midfrequency channel (22). To drive the vibrator (62) the same random frequency signal is amplitude modulated by the output of the high pass channel (20).

Assignee:

Scott Instruments Corporation - Denton TX

International Classification:

H04R 2500

US Classification:

179107FD

Abstract:

A real time cochlear implant processor (10) receives an audio input signal and extracts spectrum segments by operation of bandpass filters (18, 20). In each channel temporal circuitry detects the zero slope points of the filtered audio input signal and generates a control signal which operates a gate (66). Amplitude circuitry includes a reference voltage source for providing positive and negative polarity signals for a first mode of operation. The reference signals are routed through the gate (66) by the control signals. In a second mode of operation the audio input signal, after logarithmic amplification, is passed through the gate (66) by operation of the control signals. In a third mode of operation the audio input signal is squared through infinite clipping and the resulting signal is gated by the control signals through the gate (66). The outputs of the channels are combined in a summing circuit (78) and passed through a buffer (82) to produce a driver signal for an auditory implant electrode. The pulse outputs from the plurality of channels have different amplitudes where the higher frequency channels have lower amplitude pulses.

International Classification:

G10L 302

US Classification:

381 38

Abstract:

A method and apparatus for generating a signal transformation useful in signal processing. According to the preferred embodiment, a signal, e. g. , a speech waveform, is first converted into a sequence of digital data samples, and a reference position along a first sub-part of the sequence is then selected. A "weighted" histogram corresponding to the reference position is then generated according to a correlation function. Thereafter, a new reference position is selected, for example, at a sub-part of the sequence located a pitch period of the signal from the original reference position, and an additional histogram is generated for this sub-part. The plurality of histograms comprise the transformation of the signal, which retains a substantial part of the informational content of the original signal. Therefore, the transformation is then used as the signal itself in signal processing applications such as speech compression and synthesis.

Assignee:

Board of Trustees, Leland Stanford Jr., University

International Classification:

G10L 1500

US Classification:

704275

Abstract:

Voice activation of functions on a network such as the Internet are accomplished using a speech recognition system running synchronously with standard desktop-based Internet functions. This synchronous operation allows voice-based control to be exercised for all operations on the Internet. System functions are based on a unique combination of a local web browser, a remotely-located speech/web server, and control links between a web browser and a speech/web server. The control links provide a mechanism for controlling a speech server from a web page and a mechanism for driving both the local, as well as a remote, web browser.

International Classification:

G09B 702

US Classification:

434309

Abstract:

A method of human-machine interactive instruction with the aid of a digital computer is disclosed. The first step is providing the computer with a data base of a series of questions and answers which can be reproduced and thereafter individualized by student use by (i) providing the digital computer with a keyboarded typed question, (ii) providing the computer with a keyboarded typed answer, (iii) speaking the correct answer a plurality of times to generate relational signals for master template of the correct answer in digital form, and (iv) correlating the master template with the corresponding keyboarded typed answer. The second step is providing a human machine voice display interactive tutorial process, by for each question and answer in the data base of questions and answers, sequentially (i) displaying a typed question, (ii) displaying the corresponding correct typed answer, (iii) initiating the articulation of the correct answer by a user, (iv) processing the so-spoken answer by converting it from an audio signal into relational signals in digital form, (v) determining whether the processed spoken answer in digital form corresponds to the master template for that answer, and (vi) adjusting the master template to individualize it for the speaker if the processed spoken answer in digital form does not correspond to the master template.

Assignee:

Scott Instruments Company - Denton TX

International Classification:

G10L 500

US Classification:

381 41

Abstract:

A method and apparatus for processing a signal to extract selected information therefrom is provided. According to the method, an input signal is converted into a sequence of data samples, and these data samples are applied sequentially through a convolver having first and second sections, the output of the first section forming the input of the second section. A data sample in the second convolver section is then compared to each data sample in the first convolver section to produce an output signal of a plurality of data points, each of the data points representative of a midpoint position within the convolver between a pair of compared data samples. This comparison step is repeated for each data sample in the second convolver section and the output signals form a histogram from which the selected information is extracted. This method may be advantageously utilized in a speech recognition process for extracting various features from an input speech signal.
