    Abstract: The speech of 9 middle-class black, 9 middle-class white, 9 working-class black, and 9 workingclass white parents to their preschool children was examined during picture identification, free play, and a meal. The groups were found to be similar in the level and form of parental labeling. The groups differed in the information the parents supplied about objects in the various settings, in the parent's direction of the child's behavior, and in parental sensitivity to the child's age. Within the working-class groups, the frequency of vernacular features in the parents' speech correlated with the quality of information they provided.

    Abstract: The responses of single auditory-nerve fibers in anesthetized cats to tonal stimuli were recorded with microelectrodes. Sound-pressure levels were measured at the eardrum. After correcting for the effects of the middle ear, we were able to compare sensitivities of fibers with different characteristic frequencies. It is difficult to find a single response criterion that will serve as a satisfactory measure of sensitivity for all fibers. Data are presented to show the results of using several sensitivity measures for fibers with different rates of spontaneous activity and characteristic frequencies. The effects of previous stimulation and choice of stimulus parameters on the responses of these fibers are discussed.

    Abstract: A generalization of Laplace's formula applicable to vibrating surfaces was used to develop expressions for the equilibrium shape and position of drops and bubbles in a resonant rectangular chamber. Expanding various physical quantities in terms of spherical harmonics and applying the quantum-mechanical angular-momentum gradient formula leads to tractable expressions valid for large as well as small ka. New results for volume renormalization of drops and bubbles were also derived. The analysis takes into account acoustic radiation, surface tension, gravity, and compressibility effects. Salient features of this theory applicable to acoustic levitation will be presented. Calculated shape properties will be compared to existing results of one-dimensional theories. Also, the acoustic force dependence on ka, obtained from equilibrium position calculations, will be compared to Hasegawa's results. [Work supported by NASA.]

    Acoustical Society of America (ASA) ; 1974

    Abstract: Amplitude and phase characteristics of the two most audible combination tones (2f1 − f2) and (f2 − f1) were measured psychoacoustically on four subjects using the cancellation method. Digital stimulus generation allowed for exact phase control and continuous phase shifting. For equal level stimulus tones (f1 and f2) in cosine phase, the results generally corroborate earlier findings. That is, the amplitude of (2f1 − f2) and (f2 − f1) both decrease with increasing f2/f1 with slight changes as a function of stimulus level; (f2 − f1) phase remains relatively constant with respect to stimulus phase as a function of f2/f1, while (2f1 − f2) phase increases dramatically with increasing f2/f1. The present study covers a wide range of primary frequencies and frequency ratios; it also presents data for both (2f1 − f2) and (f2 − f1) from the same subject. Previously unreported combination-tone pitch shift as a function of cancellation-tone phase is also described.

    Equilibrium shape and location of a liquid drop acoustically positioned in a resonant rectangular chamber
    Acoustical Society of America (ASA) ; 1988

    Abstract: The effect of a standing wave field in a rectangular chamber on the shape and location of an acoustically positioned drop or bubble is calculated. The sample deformation and equilibrium position are obtained from an analysis of the spherical harmonic projections of the total surface stress tensor. The method of calculation relies on the assumed condition that the sample is only slightly distorted from a spherical form. The equilibrium location of a levitated drop is combined with a formula introduced by Hasegawa to calculate the ka dependence of the radiation force function. The present theory is valid for large as well as small ka values. Calculations in the small ka limit agree with previous theories and experimental results. Examples are presented for nonplane-wave modes as well as plane-wave rectangular modes.

    Acoustical Society of America (ASA) ; 1969

    Abstract: This paper describes a computer program that was written to analyze acoustical test data. It employs a fast Fourier subroutine to calculate the discrete Fourier coefficients that transform the time-domain data to the frequency domain. In order to achieve a more equal confidence level between the upper and lower 13 octaves, the digital data record is sampled at a high rate and the fast Fourier coefficients are calculated. Next the same digital data record is sampled at a much lower rate. This gives greater low frequency resolution to the lower 13 octaves. Consideration is given to digital windowing techniques for the purpose of comparison with analogous analysis methods and their effect on spectral representation.

    Abstract: Sixteen deaf children received therapy and were tested at four-month intervals with 15 one- and two-syllable words. These samples were judged on a 9-point similarity scale. A significant improvement was detected over the testing times. This testing procedure was described at the 79th Meeting of the Acoustical Society [C. W. Asp, J. Acoust. Soc. Am. 48, 87(A) (1970)] and some results were reported at the 84th Meeting [C. W. Asp, E. M. French, J. S. Berry, and J. E. Keller, J. Acoust. Soc. Am. 53, 349(A) (1973)] . Next, a spectrogram and a phonetic count were made of each sample which included the oral stimulus and response. For the group, there was a decrease in (1) mean F0, (2) range of F0,(3) voiced duration, (4) total duration, and (5) latency. There was an increase (improvement) in (1) syllable match and (2) phonetic count. Spectro-graphic measures were compared to similarity scores. Envelope match and syllable match had the highest correlation coefficients.

    Use of a Computer Voice-Response System for Wiring Communications Equipment
    Acoustical Society of America (ASA) ; 1973

    Abstract: Customarily, in wiring communications equipment, a production-line assembler reads and follows a complex printed list of instructions. His eyes and hands are consequently diverted from the assembly task, resulting in delays and errors. Having the wiring instructions spoken aloud, by a recorded tape, eliminates the difficulties. The tape may, of course, be recorded by a human speaker, but the procedure is burdensome. Frequent modification and updating of the instructions becomes tedious and inefficient. Also, the wire lists are typically designed by computer and exist originally in computer form. A logical step, therefore, is to have the computer speak the instructions (instead of print them), and to automatically record the computer speech on magnetic cassettes for production-line use by the assembler. We describe an automatic voice-response system implemented for this purpose. The system utilizes the Acoustics Research DDP-516 computer facility. A word library ia stored on fixed-head disk, either in data-reduced form (formant functions) or as DPCM digital waveform. A concatenation program, commanded by the input wire list, assembles, speaks, and automatically records each instruction. At this writing, eight assembly jobs have been completed for experimental use by the Western Electric Company. In the most recent, the technique has been extended from production-line assembly to central-office wiring for an ESS-1 installation.

    Abstract: Twenty young deaf children received daily auditory training and their speech reception/production was evaluated at four-month intervals with a similarity scale, a phonetic count, and a battery of acoustical measures. There was a significant improvement in similarity score for the group as a function of training. The similarity score was used to assign the children to groups. At the first evaluation, there were two groups: Group 1 had a good similarity score and Group 2 had a poor similarity score. After one year of training, Group 1 improved and had the best score; however, Group 2 split into three subgroups. Subgroup 2a showed fast progress, Group 2b had slow progress after one-year, and Group 2c had no progress. These four groups were also compared graphically for changes in phonetic count, mean F0, contour of F0, syllable match, voice duration, and latency. Groups 1 and 2a did noticeably better than Groups 2b and 2c on most of these measures. Phonetic count, mean F0, the contour of F0, and syllable match displayed differences among these four groups as a function of training.
