FORMANT ANALYSIS,

Hanne, John R. · Defense Technical Information Center (DTIC) · 1965

The investigation begins with a summary of some of the models which have been used to study speech. Closed representations of the output of a simple resonator which are synchronous with the fundamental frequency are examined as a basis of formant analysis. The representations are then discussed with respect to measured speech data. The representations are also used to specify the inherent accuracy limitations of two different formant tracking schemes. Finally, a feasibility study was made of a method of formant tracking which employs a fixed filter bank as an input to an automatic, zero crossing detector which is synchronous with the fundamental frequency. It was concluded that such a device could be built with an accuracy close to the three percent which has been reported for the human difference limen for formant frequency discrimination. (Author)

Formant-Amplitude Measurements

Gunnar Fant, K. Fintoft, Johan Liljencrants et al. · The Journal of the Acoustical Society of America · 1963

Five 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 harmonic of the voice fundamental passes through the formant center. This effect, as well as the over-all relations between the various measures, have been verified in human speech within an ensemble of sustained vowels uttered at a large variety of voice fundamental-frequency levels at constant articulation and constant voice effort. The first-formant amplitude is found to increase at a higher over-all rate than predicted from a vocal source of uniform pulses. A systematic departure from the theory of the model found in the second-formant amplitude of one of the subjects suggests a coupling between the vocal-cavity resonances and the vibrations of the vocal cords. Special requirements for formant-amplitude measurements of unvoiced sounds are discussed.

Formant-Informed Harmony

By STUDENT · 2026

This project introduces a structural model of musical harmony grounded in vocal formant theory. By aligning the harmonic spectra of musical chords with the formant frequencies of sung vowels, the model proposes a quantitative measure of spectral congruence to explain the perceptual coherence of simultaneous tones. Drawing from acoustic phonetics, auditory perception, and music theory, the study bridges symbolic harmonic analysis with the spectral characteristics of human vocalization. The model offers applications in music analysis, composition, pedagogy, and computational systems for automatic accompaniment generation. This project is part of the Structural Foundations cluster and contributes to the broader effort to ground symbolic structures in perceptual and cognitive principles.

Formant Extraction Hardware.

MS, Synthesis, Signal processing, Fourier transformation, Transfer functions, Pitch discrimination, Voice communications, Vocoders, Computer programmingFormants, *Formant analysis, Discrete Fourier transformA system for automatic extraction of speech formant frequencies, formant bandwidths, pitch, voicing and mean squared amplitude is described. The system operates on-line in one eighth real-time with a recorded speech signal and feeds the output parameters either into its own memory or to a computer interface for on-line analysis. The formant extraction system uses Atal's Adaptive Linear Predictive Coding algorithm for smoothing the speech spectrum, a discrete Fourier transform for obtaining the spectrum, and peak selection for finding the formants. Techniques for implementing the system on a 16-bit, fixed-point programmable processor and performance results are described. (Author)

Formant Weighted Cepstralfeature

For Lsp-Based Speech, Ho Young Hur, Hyung Soon Kim · 2001

In this paper, we propose a formant weighted cepstral feature for LSP-based speech recognition system. The proposed weighting scheme is based on the well-known property of LSPs that the speech spectrum has a peak when adjacent LSFs come close. By applying this scheme to pseudo-cepstrum (PCEP) conversion process [1], we can obtain formant weighted or peak enhanced cepstral feature. Results of speech recognition experiments using QCELP coder output show that the proposed feature set outperforms the conventional features such as LSP or PCEP. Moreover its performance also exceeds that of unquantized LPC cepstrum.

Average Formant Trajectories

Steven Sandoval, Rene L. Utianski, Heike Lehnert‐LeHouillier · 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 extracted at multiple time points during the duration of the vowel, rather than at a single point in time. The purpose of this study was to validate an automated method for extracting formant trajectories, using information across the time course of production, and subsequently characterize the formant trajectories of vowels using a large, diverse corpus of speech samples. Method Using software tools, we automatically extract the 1st 2 formant frequencies (F1/F2) at 10 equally spaced points over a vowel's duration. Then, we compute the average trajectory for each vowel token. The 1,600 vowel observations in the Hillenbrand database and the more than 50,000 vowel observations in the TIMIT database are analyzed. Results First, we validate the automated method by comparing against the manually obtained values in the Hillenbrand database. Analyses reveal a strong correlation between the automated and manual formant estimates. Then, we use the automated method on the 630 speakers in the TIMIT database to compute average formant trajectories. We noted that phonemes that have close F1 and F2 values at the temporal midpoint often exhibit formant trajectories progressing in different directions, hence highlighting the importance of formant trajectory progression. Conclusions The results of this study support the importance of formant trajectories over single-point measurements for the successful discrimination of vowels. Furthermore, this study provides a baseline for the formant trajectories for men and women across a broad range of dialects of Standard American English.
