“…The presence of vocal tremor in the acoustic signal is better perceived in the phonation of sustained sounds than in running speech [5,6]. This is coherent with the nature of voice tremor, that is, instabilities in the voice production system are better noticed when a stable phonation task is performed.…”

Vocal tremor has been simulated using a high-dimensional discrete vocal fold model. Specifically, respiratory, phonatory, and articulatory tremors have been modeled as instabilities in six parameters of the model. Reported results are consistent with previous knowledge in that respiratory tremor mainly causes amplitude modulation of the voice signal while laryngeal tremor causes both amplitude and frequency modulation. In turn, articulatory tremor is commonly assumed to produce only amplitude modulations but the simulation results indicate that it also produces a high-frequency modulation of the output signal. Furthermore, articulatory tremor affects the frequency response of the vocal tract and it might thus be detected by analyzing the spectral envelope of the acoustic signal.

“…However, the question of what type of voice sample is most appropriate for acoustic and/or perceptual analysis has been controversial, resulting in a number of studies examining the relative suitability of sustained vowels versus samples of continuous speech (e.g., Lederle, Barkmeier-Kraemer, & Finnegan, 2012;Maryn & Roy, 2012;Moon, Chung, Park, & Kim, 2012;Zraick, Wendel, & Smith-Olinde, 2005). Arguments in favor of measuring voice quality from sustained vowels contend they are relatively time invariant; free from influences of phonetic context and thereby unaffected by intonation, stress, or speaking rate; easy to elicit, produce, and analyze; more easily controlled; and less affected by the dialect of the speaker and/or listener than continuous speech is (Maryn, Corthals, Van Cauwenberge, Roy, & De Bodt, 2010a;Zraick et al, 2005).…”

“…Further, speech elicited in specific phonetic contexts, such as those used in the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V; Kempster, Gerratt, Verdolini Abbott, Barkmeier-Kraemer, & Hillman, 2009), can reveal the existence and nature of some voice disorders (e.g., vocal tremor [Lederle et al, 2012] and adductory spasmodic dysphonia) that may occur more commonly under certain circumstances (at voicing onsets and/or offsets, for example, Awan et al, 2010;Roy, Gouse, Mauszycki, Merrill, & Smith, 2005). However, most acoustic studies of quality assessment from continuous speech use means and/or standard deviations for acoustic measures calculated across the entire sample of speech, and perceptual studies usually assess the overall extent of dysphonia (e.g., Awan, Roy, & Dromey, 2009;de Krom, 1994;Halberstam, 2004;Lederle et al, 2012;Lowell, Colton, Kelley, & Hahn, 2011;Maryn et al, 2010a;Maryn & Roy 2012;Moon et al, 2012;Parsa & Jamieson, 2001;Revis, Giovanni, Wuyts, & Triglia, 1999;Watts & Awan, 2011;Zraick et al, 2005;see Lowell, 2012, or Maryn, Roy, De Bodt, Van Cauwenberge, & Corthals, 2009 This approach limits the extent to which such measures can index quality variations in continuous speech rather than simply overall levels of dysphonia.…”

Purpose:The question of what type of utterance-a sustained vowel or continuous speech-is best for voice quality analysis has been extensively studied but with equivocal results. This study examines whether previously reported differences derive from the articulatory and prosodic factors occurring in continuous speech versus sustained phonation. Method: Speakers with voice disorders sustained vowels and read sentences. Vowel samples were excerpted from the steadiest portion of each vowel in the sentences. In addition to sustained and excerpted vowels, a 3rd set of stimuli was created by shortening sustained vowel productions to match the duration of vowels excerpted from continuous speech. Acoustic measures were made on the stimuli, and listeners judged the severity of vocal quality deviation. Results: Sustained vowels and those extracted from continuous speech contain essentially the same acoustic and perceptual information about vocal quality deviation. Conclusions: Perceived and/or measured differences between continuous speech and sustained vowels derive largely from voice source variability across segmental and prosodic contexts and not from variations in vocal fold vibration in the quasisteady portion of the vowels. Approaches to voice quality assessment by using continuous speech samples average across utterances and may not adequately quantify the variability they are intended to assess.

“…Participants were instructed to "guess" if they were unsure which item in the pair was shakier. Shaky was selected as the descriptor based on Lederle et al (2012) and Lester and Story (2015).…”

“…These acoustical modulations lead to the perception of a "shaky" sounding voice (Lederle et al, 2012) and increased effort when speaking (Sulica and Louis, 2010). Behavioral treatment of vocal tremor primarily focuses on training voluntary voice adjustments that reduce the perceptual severity of vocal tremor (Barkmeier-Kraemer et al, 2011).…”

The purpose of this study was to investigate the effects of physiological adjustments on listeners' perception of the magnitude of modulation of voice and to determine the characteristics of the acoustical modulations that explained listeners' judgments. This research was carried out using singers producing vibrato as a model of vocal tremor. Twenty healthy adults participated in a perceptual study involving pair-comparisons of the magnitude of "shakiness" with singers' samples, which differed by fundamental frequency, vocal quality, and vowel. Results revealed that listeners perceived a higher magnitude of voice modulation when female samples had a pressed vocal quality. Acoustical analyses were performed with voice samples to determine the features that predicted listeners' judgments. Based on regression analyses, listeners' judgments were predicted to some extent by modulation information in frequency bands across the spectrum.
