Robust Copy–Move Detection of Speech Recording Using Similarities of Pitch and Formant

IEEE Transactions on Information Forensics and Security, 2019
Copy–move forgery on very short speech segments, followed by post-processing operations to eliminate traces of the forgery, presents a great challenge to forensic detection.

On subglottal formant analysis

The Journal of the Acoustical Society of America, 1987
When subglottal pressure signals which are recorded during normal speech production are spectrally analyzed, the frequency of the first spectral maximum appears to deviate appreciably from the first resonance frequency which has been reported in the literature and which stems from measurements of the acoustic impedance of the subglottal system.

Formant estimation and tracking: A deep learning approach.

Journal of the Acoustical Society of America, 2019
Formant frequency estimation and tracking are among the most fundamental problems in speech processing. In the estimation task, the input is a stationary speech segment such as the middle part of a vowel, and the goal is to estimate the formant ...

The Speaker's Formant

Journal of Voice, 2006
The current study concerns speaking voice quality in two groups of professional voice users, teachers (n = 35) and actors (n = 36), representing trained and untrained voices. The voice quality of text reading at two intensity levels was acoustically analyzed. The central concept was the speaker's formant (SPF), related to the perceptual characteristics

The role of formant-frequency contours in the perceptual grouping of speech formants.

The Journal of the Acoustical Society of America, 2011
The perceptual organization of speech remains poorly understood. Recent research using sine-wave speech suggests that the ability of an extraneous formant to impair intelligibility depends on modulation of its frequency contour [Roberts et al., J. Acoust. Soc. Am. 128, 804–817].

The speaker's formant in male voices

Journal of Voice, 1997
Spectral analysis of vowels during connected speech can be performed using the spectral intensity distribution within critical bands corresponding to a natural scale on the basilar membrane. Normalization of the spectra provides the opportunity to make objective comparisons independent from the recording level. An increasing envelope peak between 3,150

Articulatory interpretation of the “singing formant”

The Journal of the Acoustical Society of America, 1974
The “singing formant” is a high spectrum envelope peak near 2.8 kHz characteristic of vowel sounds produced in male Western opera and concert singing. An acoustical model of the vocal tract is capable of generating such a peak provided that three conditions are met: (1) The cross-sectional area in the pharynx must be at least six times wider than that ...

Formant-Frequency Variation and Its Effects on Across-Formant Grouping in Speech Perception

2013
How 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.

The ?telephone effect? on formants: a response

Forensic Linguistics, 2002
This article is a response to Hermann Künzel's article ‘Beware of the telephone effect”: the influence of telephone transmission on the measurement of formant frequencies’ (Forensic Linguistics 8(1), 80–99). There, he shows convincingly that the evaluation of formant frequencies, notably F1, is affected by the band-pass filter effect of telephone ...
