The effect of a voiced lip trill on estimated glottal closed quotient.
  • C. Gaskill, M. Erickson
  • Psychology, Medicine
  • Journal of voice : official journal of the Voice…
  • 1 November 2008
TLDR
Most participants showed a tendency for a reduction in CQ during the lip trill, with a more pronounced change in the untrained participants, which is similar to other studies on vocal fold vibration. Expand
A Rule of Thumb: The Bandwidth for Timbre Invariance Is One Octave
TLDR
Listeners could not determine whether two different notes separated by an octave or more were played by the identical or a different wind instrument and similarly were unable to determine whether a vowel sung at different pitches separated by more was sung by the same soprano or mezzo-soprano. Expand
Discrimination functions: can they be used to classify singing voices?
TLDR
The ability to correctly choose the odd person varied greatly depending on pitch factors, suggesting that the traditional concept of an invariant timbre associated with a singer is inaccurate and that vocal timbre must be conceptualized in terms of transformations in perceived quality that occur across an individual singer's range and/or registers. Expand
The effect of an artificially lengthened vocal tract on estimated glottal contact quotient in untrained male voices.
TLDR
The results indicate that the use of resonance tubes can have a distinct effect on glottal closure, but the mechanism behind this change remains unclear. Expand
Sound Source Identification: The Possible Role of Timbre Transformations
Timbre is typically investigated as a perceptual attribute that differentiates instruments at one pitch. Yet the perceptual usefulness of timbre is that it allows listeners to recognize oneExpand
The interaction of formant frequency and pitch in the perception of voice category and jaw opening in female singers.
  • M. Erickson
  • Psychology, Medicine
  • Journal of voice : official journal of the Voice…
  • 1 March 2004
TLDR
Listeners appeared to need agreement between all four formants to perceive voice categories, and when upper and lower formants are inconsistent in frequency, listeners were unable to judge voice category, but they could use the inconsistent patterns to form perceptions about degree of jaw opening. Expand
Dissimilarity and the classification of male singing voices.
  • M. Erickson
  • Psychology, Medicine
  • Journal of voice : official journal of the Voice…
  • 1 May 2008
TLDR
Using stimuli produced across the singing range by singers from different voice categories, this study sought to examine how timbre and pitch interact in the perception of dissimilarity in male singing voices and found that inexperienced listeners appeared to rely more heavily on pitch in making Dissimilarity judgments than did experienced listeners.

Simultaneous effects on vowel duration in American English: a covariance structure modeling approach.
  • M. Erickson
  • Mathematics, Medicine
  • The Journal of the Acoustical Society of America
  • 21 November 2000
TLDR
Results suggest that covariance structure analysis can be used as a complementary technique in linguistic and phonetic research and suggest whether a single population model of vowel duration fits observed data better than a dual population model. Expand
Effects of voicing and syntactic complexity on sign expression in adductor spasmodic dysphonia.
  • M. Erickson
  • Medicine
  • American journal of speech-language pathology
  • 1 November 2003
TLDR
ADSD signs were significantly more frequent in predominantly voiced sentences than in predominantly voiceless sentences, regardless of level of syntactic complexity, which has important implications for the assessment of ADSD. Expand
Dissimilarity and the classification of female singing voices: a preliminary study.
  • M. Erickson
  • Psychology, Medicine
  • Journal of voice : official journal of the Voice…
  • 1 June 2003
TLDR
Using stimuli produced across the singing range by singers from different voice categories, this study sought to examine how timbre and pitch interact in the perception of dissimilarity and provided a glimpse of the timbre transformation of voice categories across pitch. Expand
