Formant-Amplitude Measurements
The Journal of the Acoustical Society of America, 1963Five alternative measures of formant amplitude are defined from circuit-theory analysis of speech production. Each of these is studied analytically as a function of increasing voice fundamental frequency, assuming constant shape and size of voice-source pulses. Some of the formant-amplitude measures display periodic fluctuations with maxima each time a

One of the principal problem areas in the perfection of the formant-tracker speech-compression system lies in the extraction with the utmost of precision of the formant traces that are pertinent to the preservation in speech of the articulatory events. Under a current research effort [sponsored by the U. S.

This paper describes analysis and synthesis methods for a digital formant synthesizer. It is shown that synthetic speech generated using excitation pulses which resemble the true glottal volume-velocity excitation waveform is preferred over speech synthesized using a two-pole glottal filter and impulse excitation.

Perspectives of the ASHA Special Interest Groups, 2019
Purpose The use and study of formant frequencies for the description of vowels is commonplace in acoustic phonetics and in attempts to understand results of speech perception studies. Numerous studies have shown that listeners are better able to distinguish vowels when the acoustic parameters are based on spectral information ...

The attempt to build a talking machine has a long history and can even be traced back to a time before the beginning of the Christian era (Linggard, 1985). The first complete talking machine is due to von Kempelen (1791) and is described in a book of over 400 pages that also reports on the twenty or so years of experimentation that were needed to build

Auditory feedback shifts in one formant cause multi-formant responses.
The Journal of the Acoustical Society of America, 2010Talkers are known to compensate for experimentally-induced shifts in auditory feedback. In a typical experiment, talkers might hear their F1 feedback shifted (so that [ε] sounds like [æ], for example), and compensate by lowering F1 in their subsequent speech.

Adaptive control of vowel formant frequency: Evidence from real-time formant manipulation
The Journal of the Acoustical Society of America, 2006Auditory feedback during speech production is known to play a role in speech sound acquisition and is also important for the maintenance of accurate articulation. In two studies the first formant (F1) of monosyllabic consonant-vowel-consonant words (CVCs) was shifted electronically and fed back to the participant very quickly so that participants ...

This series of experiments examines the relation between the basic capabilities of the peripheral auditory system to process speech and the classification of speech at more central levels. Psychophysical techniques have been applied to determine listeners’ abilities to detect, discriminate, and identify speech sounds.

Formant-Frequency Variation and Its Effects on Across-Formant Grouping in Speech Perception
2013How speech is separated perceptually from other speech remains poorly understood. In a series of experiments, perceptual organisation was probed by presenting three-formant (F1+F2+F3) analogues of target sentences dichotically, together with a competitor for F2 (F2C), or for F2+F3, which listeners must reject to optimise recognition.
