A significant body of evidence has accumulated indicating that vowel identification is influenced by spectral change patterns. For example, a large-scale study of vowel formant patterns showed substantial improvements in category separability when a pattern classifier was trained on multiple samples of the formant pattern rather than a single sample at steady state [J. Hillenbrand et al., J. Acoust. Soc. Am. 97, 3099-3111 (1995)]. However, in the earlier study all utterances were recorded in a… 
Modeling of vowel-inherent spectral change in spontaneous and elicited speech
A database of speech samples was collected to examining vowel formant patterns in spontaneous and read speech. Recordings were made from 220 long-time residents of Nova Scotia and Prince Edward
Amplitude variations in coarticulated vowels.
TLDR
Auditory spectra showed that the pattern of spectral amplitude variation as a function of contextual effects may still be encoded and represented at early stages of processing by the peripheral auditory system.
Modeling consonant-context effects in a large database of spontaneous speech recordings.
Given recent interest in the analysis of naturally produced spontaneous speech, a large database of speech samples from the Canadian Maritimes was collected, processed, and analyzed with the primary
The Relative Amplitude of Vowel Formants for Vowels in Asymmetrical Consonant Contexts
The objective of this research is to characterize the role of the relative intensity of speech segments in the auditory processing of vowels and consonants within larger prosodic domains such as
Identification of resynthesized /hVd/ utterances: effects of formant contour.
TLDR
Pattern recognition results showed that a simple approach to vowel specification based on duration, steady-state F0, and formant frequency measurements at 20% and 80% of vowel duration accounts for much but by no means all of the variation in listeners' labeling of the three types of stimuli.
Theories of Vowel Inherent Spectral Change
In many dialects of North-American English, in addition to vowels which are traditionally described as true and phonetic diphthongs, several vowels traditionally described as monophthongs also have
Formant Trajectories of English Vowels Produced by American Children
Formant values are the most important acoustic correlates of English vowels. Classical studies on English vowels reported the first three formant values measured at a single timepoint on a sustained
Cross-dialectal variation in formant dynamics of American English vowels.
TLDR
Results revealed expected variation in formant dynamics as a function of phonetic factors (vowel emphasis and consonantal context), however, for each vowel and for each measure employed, dialect was a strong source of variation in vowel-inherent spectral change.
Do Isolated Vowels Represent Vowel Targets in French? An Acoustic Study On Coarticulation
Coarticulatory effects of labial, dental, palato-velar and uvular places of articulation on vowel targets of ten French oral vowels /i, e, ɛ, a, u, o, ɔ, y, o, œ/ were examined. The average vowel
Some effects of duration on vowel recognition.
TLDR
Duration had a small overall effect on vowel identity since the great majority of signals were identified correctly at their original durations and at all three altered durations, and a simple pattern recognition model appears to be capable of accounting for several features of the listening test results.

Dynamic specification of coarticulated vowels.
TLDR
Dynamic spectral information, contained in initial and final transitions taken together, was sufficient for accurate identification of vowels even when vowel nuclei were attenuated to silence and appeared to be efficacious even when durational parameters specifying intrinsic vowel length were eliminated.
Acoustic characteristics of American English vowels.
TLDR
Analysis of the formant data shows numerous differences between the present data and those of PB, both in terms of average frequencies of F1 and F2, and the degree of overlap among adjacent vowels.
Identification of vowels in “vowelless” syllables
TLDR
Two vowel-perception experiments revealed the importance of dynamic spectral information at syllable onset and offset (in its proper temporal relation) in permitting vowel identification, and deprived of its durational variation, steady-state spectral information was a poor basis for identification.
General contrast effects in speech perception: Effect of preceding liquid on stop consonant identification
TLDR
The results of the present study suggest an explanation in terms of general auditory processes as opposed to recovery of or knowledge of specific articulatory dynamics.
On the sufficiency of compound target specification of isolated vowels and vowels in /bVb/ syllables.
TLDR
For speakers of Western Canadian English coarticulatory cues appear to play at best a minor role in the perception of vowels in /bVb/ context, while vowel-inherent factors dominate listeners' perception.
Vowel identification: orthographic, perceptual, and acoustic aspects.
TLDR
Results support recent finding that isolated vowels may be readily identified by listeners and show improvement in the fixed speaker context is correlated with improved statistical separation resulting from formant normalization, for the gated vowels.

TLDR
It is shown that time-varying information is necessary for accurate identification of coarticulated vowels and two hypotheses about the nature of the dynamic information specified over syllable onsets and offsets are discussed.
Spectral-shape features versus formants as acoustic correlates for vowels.
TLDR
In this study automatic vowel classification experiments were used to compare formants and spectral- shape features for monopthongal vowels spoken in the context of isolated CVC words, and it was concluded that spectral-shape features are a more complete set of acoustic correlates for vowel identity than are formants.
Identification of steady-state vowels synthesized from the Peterson and Barney measurements.
TLDR
To determine how well listeners can identify vowels based exclusively on static spectral cues, listeners were asked to identify steady-state synthesized versions of 1520 vowels using Peterson and Barney's measured values of F0 and F1-F3.

TLDR
The present work reviews theories and empirical findings that bear on the perception of English vowels, with an emphasis on the comparison of data analytic "machine recognition" approaches with results from speech perception experiments.
