[Complex voice assessment--Polish version of the Voice Handicap Index (VHI)].

The aim of this work was to present own modification of Jacobson's The Voice Handicap Index, the self-estimation scale of the voice as a one part of the complex voice evaluation. The VHI contains three groups of questions of physical, emotional and functional subscales, which specify complaints during phonation scored in 4 points (0-4). The presented our own modification of the VHI may be useful in everyday clinical practice.

[A proposal to adapt the voice handicap index to the singing voice].

OBJECTIVES: The voice handicap index by Jacobson et al doesn't render the difficulties experienced by singers. The aim of this study is to adapt the V.H.I. to the singing voice and evaluate it's reliability and coherence. In order to obtain this first scale, we went through three stages. MATERIAL ET METHOD: The first consisted in the modification of the existing items and the creation of new ones. The second was to measure the stability by a test - retest and the coherence of the adapted and the new items. This was done on groups of dysodic singers and professional voice users. The third stage consisted in evaluating the reliability and the coherence of 31 items on a homogeneous population of 132 classical singers with and without vocal impairment. The subjects were divided in three groups. The first group was composed of 95 normophonic singers, the second included 37 dysphonic singers and the third group was the control group, composed of 20 non singers without vocal complaints. RESULTS: The statistical results show a good stability of the test - retest (ICC=0.949; Rho: 0.912; Bland et Altman [-010.19, +13.23]). The internal coherence of each sub scale (Cronbach's alpha) is good (>0.70). The correlations between the three sub scales are moderate between the functional and the emotional sub scale: 0.58; between the emotional and the physical: 0.64; and between the functional and the physical: 0.78). Each sub scale is measuring a specific dimension; still they are homogeneous between one another. Four variables have a significative influence on the results: the pathology (p<0.001), being a professional singer (p<0.001), the repetition (p=0.003), being a chorister (p=0.002). CONCLUSION: The VH.I adapted to the singers, appears to be reliable, valid and adapted to the population of dysodic classical singers.

[Functional voice quality assessment in curative microsurgery of laryngeal malignancies. Postoperative voice rehabilitation based on the "laryngeal double valve function"].

According to Negus and Pressman the sphincter systems of the vocal folds and the ventricular folds form a respiratory "laryngeal double valve function". Correspondingly, we found a physiological phonation system of the glottis and a pathological-compensatory one of the supraglottis. They appear to be regulated through an automatic phonatory control system with the glottal phonatory function evidently acting as sensor level. In order to confirm this hypothesis, objective voice analyses with glottal-relevant parameters of 26 voice-rehabilitated patients after minimally invasive laser surgery of glottal carcinomas are presented and integrated into a "hoarseness diagram" with the coordinates roughness and breathiness. Using statistically deliminated acoustic dusters, our data show a qualitative hierarchy of different postoperative phonation mechanisms. They demonstrate the influence of the vibratory capacity of glottal and supraglottal structures on the quality of the vibratory closure. Both functional parameters evidently determine the resulting voice quality in the sense of our hypothesis.

Thinking the voice: neural correlates of voice perception.

The human voice is the carrier of speech, but also an "auditory face" that conveys important affective and identity information. Little is known about the neural bases of our abilities to perceive such paralinguistic information in voice. Results from recent neuroimaging studies suggest that the different types of vocal information could be processed in partially dissociated functional pathways, and support a neurocognitive model of voice perception largely similar to that proposed for face perception.

High-speed imaging of the voicing source in laryngectomees during production of voiced-voiceless distinctions for stop consonants.

This study presents results from high-speed imaging recordings of the voice source, that is the pharyngo-esophageal segment, in four laryngectomized men. The subjects were asked to produce VCV-syllables with voiced and voiceless stop consonants during simultaneous high-speed imaging recordings and audio recordings. A general and detailed visuo-perceptual analysis of the shape and vibratory pattern in the pharyngo-esophageal (PE-) segment was made, as well as acoustical measurements of voice onset time (VOT) and closure duration for each syllable. The syllables were also audio-perceptually evaluated by five expert listeners. Results show that the subjects had a high overall intelligibility as judged by the listeners. All four subjects were able to make opening gestures in the PE-segment while producing voiceless stop consonants. In cases where misperceptions were predominant, the acoustical analysis with spectrograms and the detailed analysis of the vibration in the PE-segment gave information about probable causes of the mishearings.

The role of F1 in the perception of voice onset time and voice offset time.

An important speech cue is that of voice onset time (VOT), a cue for the perception of voicing and aspiration in word-initial stops. Preaspiration, an [h]-like sound between a vowel and the following stop, can be cued by voice offset time, a cue which in most respects mirrors VOT. In Icelandic VOffT is much more sensitive to the duration of the preceding vowel than is VOT to the duration of the following vowel. This has been explained by noting that preaspiration can only follow a phonemically short vowel. Lengthening of the vowel, either by changing its duration or by moving the spectrum towards that appropriate for a long vowel, will thus demand a longer VOffT to cue preaspiration. An experiment is reported showing that this greater effect that vowel quantity has on the perception of VOffT than on the perception of VOT cannot be explained by the effect of F1 frequency at vowel offset.

Normative voice range profiles of male and female professional voice users.

Normative voice range profiles (VRP) are calculated for a group of male and female teachers, based on 43 and 46 recordings, respectively. All individuals had healthy voices. These normative VRPs contain 95% prediction intervals for both frequency and intensity. They are based on a series of mathematical transformations of the original individual VRPs in order to maintain in the normative VRPs the typical oval VRP shape, including the dip between modal and falsetto register. The normative VRPs presented are directly applicable in the clinical practice of otolaryngologists and speech-language pathologists.

Voice outcome measures: correlations with patients' assessment of their condition and the effectiveness of voice therapy.

This study investigated correlations between voice outcome measures. Participants' ratings from the Voice Handicap Index (VHI) and a self-rating scale of vocal impairment (SRS) were compared with perceptual assessment (using GRBAS) and acoustic analysis of sustained vowels and connected speech. The measures were taken from ten female participants, pre- and post-therapy. Correlations between pre-therapy measures were generally stronger than between post-therapy measures; and parameters significantly related to participants' assessment of their condition differed from those related to participants' perceptions of improvement. Within the framework of the importance of multidimensional outcome measures, it is recognized that interdimensional relationships need not necessarily exist. For certain parameters, this appeared to be the case.

Voice restoration with the advantage tracheoesophageal voice prosthesis.

OBJECTIVES: To determine whether the Blom-Singer indwelling Advantage tracheoesophageal voice prosthesis (TEP) extends prosthesis life span significantly in patients with documented premature device failure due to fungal colonization. STUDY DESIGN AND SETTING: Data were collected in a prospective manner on a total of 42 standard indwelling TEP users who exhibited early device failure, that is, between 2 weeks and 6 months, due to fungal colonization of the flap valve despite appropriate use of oral antifungal agents. There were 29 men and 13 women, whose ages ranged from 36 years 10 months to 86 years 8 months. METHODS: Baseline data were derived from the average number of days 3 previous standard indwelling prostheses functioned before leaking. An Advantage indwelling TEP was placed after the third change, oral antifungal agents stopped, and routine care implemented, that is, flush and brush the device in situ twice each day. Each participant was assigned to 1 of 3 groups. Group 1 had device failure equal to or less than 2 months (n = 12). Group 2 had device failure between 2 and 4 months (n = 19). Group 3 had device failure between 4 and 6 months (n = 11). RESULTS: Groups 1 and 2 exhibited significantly longer device life span, that is, 77 and 82 days, respectively (P < 0.01), and group 3 exhibited device life span that was longer but not significantly so, that is, 12 days (P > 0.05), after the change from standard to Advantage TEP. Individual data indicated that the majority of participants, that is, 32 of 42 (76.2%), experienced longer device life span after changing to the Advantage prosthesis. Specifically, 9 of 12 (75.0%) users in group 1, 17 of 19 (89.5%) users in group 2, and 6 of 11 (54.5%) users in group 3 exhibited longer device life span. The combination of using an Advantage TEP, discontinuing oral antifungal agents, and reducing the number of both TEP changes and clinic visits resulted in overall cost benefits for both the user and the health care system. The cost benefit for group 1 was dollar 520.00; group 2, dollar 393.00; and group 3, dollar 204.25. CONCLUSIONS: The Advantage TEP extended device life span significantly for standard indwelling device users with documented premature device failure due to fungal colonization, reduced costs associated with tracheoesophageal voice restoration rehabilitation, and enhanced user satisfaction by eliminating use of oral antifungal agents and reducing clinic visits. SIGNIFICANCE: Use of an Advantage indwelling voice prosthesis is warranted from both cost and user satisfaction perspectives when early and repeated device failure occurs as a result of fungal colonization. EBM RATING: B-3.

Using quality function deployment to capture the voice of the customer and translate it into the voice of the provider.

BACKGROUND: Health care has a number of historical barriers to capturing the voice of the customer and to incorporating customer wants into health care services, whether the customer is a patient, an insurer, or a community. Quality function deployment (QFD) is a set of tools and practices that can help overcome these barriers to form a process for the planning and design or redesign of products and services. The goal of the project was to increase referral volume and to improve a rehabilitation hospital's capacity to provide comprehensive medical and/or legal evaluations for people with complex and catastrophic injuries or illnesses. HIGH-LEVEL VIEW OF QFD AS A PROCESS: The steps in QFD are as follows: capture of the voice of the customer, quality deployment, functions deployment, failure mode deployment, new process deployment, and task deployment. The output of each step becomes the input to a matrix tool or table of the next step of the process. CASE STUDY EXAMPLE: In 3 1/2 months a nine-person project team at Continental Rehabilitation Hospital (San Diego) used QFD tools to capture the voice of the customer, use these data as the basis for a questionnaire on important qualities of service from the customer's perspective, obtain competitive data on how the organization was perceived to be meeting the demanded qualities, identify measurable dimensions and targets of these qualities, and incorporate the functions and tasks into the delivery of service which are necessary to meet the demanded qualities. DISCUSSION: The future of providing health care services will belong to organizations that can adapt to a rapidly changing environment and to demands for new products and services that are produced and delivered in new ways.

Voices during sex: application of voice therapy to sexuality.

Negative cognitions are capable of interfering with the natural flow of excitement and sexual desire at any point prior to, during, or following a sexual encounter. The source of these inimical thought patterns can be found in internalized parental attitudes that are transmitted intergenerationally and that also form the basis of sexual stereotyping. This paper describes the application of Voice Therapy methods to the resulting sexual problems manifested in many couple relationships. Clinical material excerpted from group sessions illustrate the content of the "voice" process--the negative cognitions--and demonstrate the angry affect that accompanies the verbalization of such thoughts and attitudes. Exposing self-attacks and critical thoughts about one's partner has proved to have positive results in terms of improved sexual relationships. Also discussed are those prevailing cultural views that function to reinforce each individual's "voice," thereby contributing to much of the sexual distress experienced in personal relationships.

The delayed trigger voice key: an improved analogue voice key for psycholinguistic research.

Many researchers rely on analogue voice keys for psycholinguistic research. However, the triggering of traditional simple threshold voice keys (STVKs) is delayed after response onset, and the delay duration may vary depending on initial phoneme type. The delayed trigger voice key (DTVK), a stand-alone electronic device that incorporates an additional minimum signal duration parameter, is described and validated in two experiments. In Experiment 1, recorded responses from a nonword naming task were presented to the DTVK and an STVK. As compared with hand-coded reaction times from visual inspection of the waveform, the DTVK was more accurate than the STVK, overall and across initial phoneme type. Rastle and Davis (2002) showed that an STVK more accurately detected an initial [s] when it was followed by a vowel than when followed by a consonant. Participants' responses from that study were presented to the DTVK in Experiment 2, and accuracy was equivalent for initial [s] in vowel and consonant contexts. Details for the construction of the DTVK are provided.

Voice restoration after total laryngectomy with tracheoesophageal puncture and voice prosthesis.

Removal of the voice box or larynx is the usual treatment for advanced cancer of the larynx. Tracheoesophageal puncture (TEP) has become an accepted method for voice restoration following total laryngectomy. Eleven patients under went total laryngectomy with TEP at San Pablo Hospital Medical Center between March 1989 and October 1995. Seven patients were available for voice analysis. Eighty six percent of the patient was able to talk. This is the first report of TEP being perform in Puerto Rico and with a complete Hispanic population of patients. Results compare favorably with those reported in the medical literature.

Pitch matching accuracy of trained singers, untrained subjects with talented singing voices, and untrained subjects with nontalented singing voices in conditions of varying feedback.

At a physiological level, the act of singing involves control and coordination of several systems involved in the production of sound, including respiration, phonation, resonance, and afferent systems used to monitor production. The ability to produce a melodious singing voice (eg, in tune with accurate pitch) is dependent on control over these motor and sensory systems. To test this position, trained singers and untrained subjects with and without expressed singing talent were asked to match pitches of target pure tones. The ability to match pitch reflected the ability to accurately integrate sensory perception with motor planning and execution. Pitch-matching accuracy was measured at the onset of phonation (prephonatory set) before external feedback could be utilized to adjust the voiced source, during phonation when external auditory feedback could be utilized, and during phonation when external auditory feedback was masked. Results revealed trained singers and untrained subjects with singing talent were no different in their pitch-matching abilities when measured before or after external feedback could be utilized. The untrained subjects with singing talent were also significantly more accurate than the trained singers when external auditory feedback was masked. Both groups were significantly more accurate than the untrained subjects without singing talent.

Objective measures of voice production in normal subjects following prolonged voice use.

Laryngeal fatigue affects the physical sensations, effort, and perceptual quality of voice production. The underlying physiology of fatigue is not well understood. Acoustic, aerodynamic, and videostroboscopic data were measured in 10 normal speakers before and after prolonged voice use. Significant changes were found in the fundamental frequency of connected speech. Anterior glottal chinks were induced in a majority of subjects. Implications are discussed.

Effects of intensive voice treatment (the Lee Silverman Voice Treatment [LSVT]) on ataxic dysarthria: a case study.

This study examined the effects of intensive voice treatment (the Lee Silverman Voice Treatment [LSVT]) on ataxic dysarthria in a woman with cerebellar dysfunction secondary to thiamine deficiency. Perceptual and acoustic measures were made on speech samples recorded just before the LSVT program was administered, immediately after it was administered, and at 9 months follow-up. Results indicate short- and long-term improvement in phonatory and articulatory functions, speech intelligibility, and overall communication and job-related activity following LSVT. This study's findings provide initial support for the application of LSVT to the treatment of speech disorders accompanying ataxic dysarthria. Potential neural mechanisms that may underlie the effects of loud phonation and LSVT are addressed.

[Analysis of voice parameters after conservative treatment of laryngeal paralysis with conventional voice exercises or neuromuscular electrophonatory stimulation].

Two groups of patients with unilateral or bilateral paresis of the nervus laryngeus inferior were treated with conventional voice therapy or neuromuscular electrophonatory stimulation (NMEPS). A few had additional paresis of the nervus laryngeus superior. After therapy pareses resolved or were compensated for. Successful therapy outcome can be verified on the basis of voice quality parameters. Significant improvements for both therapy groups were observed in case of parameters indicating frequency irregularities and noise-to-harmonic ratio. Only the patients treated with NMEPS reached significantly better results in case of soft phonation index after resolution of paresis.
