Purpose: To examine the voice and personality characteristics of patients diagnosed with organic dysphonia secondary to vocal fold immobility. Methods: The study comprised patients of both genders, attending the Clinic School of Speech Therapy of the Federal University of Paraíba, with otorhinolaryngological diagnosis of vocal fold immobility and speech therapy diagnosis of dysphonia. The self-assessment of voice was measured through a Vocal Screening Protocol and Voice Symptoms Scale (VoiSS), the voice was collected for auditory-perceptive evaluation, and the Factorial Personality Battery (FPB) was used. Descriptive statistical analysis was performed to determine the frequency, mean, and standard deviation of the studied variables. Results: Eight patients participated in the study, of both genders, with average age of 40.4±16.9 years. The more frequent risk factors were the personal ones (4.7±2.1). In the VoiSS, the patients presented a higher average in the limitation score (34.1±15.7). From the auditory-perceptive evaluation, moderate intensity of vocal deviation was obtained, with predominant vocal roughness (57.7±25.2). In the FPB, the patients had an average higher than the cutoff scores in neuroticism (3.8±1.4) and accomplishment (5.2±1.0). Conclusion: The predominant vocal parameter was roughness. The patients referred to a few risk factors that compromise the vocal behavior and presented the neuroticism and realization factors as a highlight in their personality. Thus, individuals with vocal fold immobility show personality characteristics that may be a reflection of their voice disorder, not a factor that determines their dysphonia.

Introduction. There are subjective and objective ways to examine the effects of vocal therapy in voice disorders. The most precise and objective check-up is the use of computer voice analysis. Objective. The aim of the research was to perform a detailed analysis of acoustic structure of the vowel A before and after voice treatment in patients with vocal fold nodules in order to obtain objective verification of the vocal rehabilitation success. Methods. We examined 30 female patients, aged 34.6?6.69 years, with vocal fold nodules. Acoustic parameters of voice were compared with the control group consisting of 21 subjects without voice pathology. In all persons the vowel A was recorded and analyzed before and after a month of vocal therapy. The success of the vocal therapy was tracked using computer analysis of vocal structure. Signal, noise and tremor parameters were processed. Results. Of the analyzed vowel A parameters: STD, PER, JITA, JITT, RAP, vFO, ShdB, SHIM, APQ, VTI, SPI, F0, NHR, FTRI, eleven improved (p<0.05 and p<0.01). Three parameters (F0, NHR, FTRI) changed showing improvement, but the obtained differences were not statistically significant (p>0.05). Conclusion. Based on the obtained results it was concluded that vocal therapy gave satisfactory results, but that it should be continually applied until full stabilization of the voice.

Insight Into

A study was undertaken to analyse the effect of short-term intubation on the voice. Children were examined laryngographically both pre- and postoperatively. Changes in larynx frequency distribution following intubation were documented using the technique of electrolaryngography; the resolution of these changes was similarly recorded. The results, in comparison with the frequency distributions associated with other disease states, give insight into the nature of the damage and its effect on vocal fold vibratory patterns. The technique therefore enables objective evidence of minor degrees of laryngeal trauma to be demonstrated and differentiated.

The Voice

The function of the voice organ is basically the same in classical singing as in speech. However, loud orchestral accompaniment has necessitated the use of the voice in an economical way. As a consequence, the vowel sounds tend to deviate considerably from those in speech. Male voices cluster formant three, four, and five, so that a marked peak is produced in spectrum envelope near 3,000 Hz. This helps them to get heard through a loud orchestral accompaniment. They seem to achieve this effect by widening the lower pharynx, which makes the vowels more centralized than in speech. Singers often sing at fundamental frequencies higher than the normal first formant frequency of the vowel in the lyrics. In such cases they raise the first formant frequency so that it gets somewhat higher than the fundamental frequency. This is achieved by reducing the degree of vocal tract constriction or by widening the lip and jaw openings, constricting the vocal tract in the pharyngeal end and widening it in the mouth. These deviations from speech cause difficulties in vowel identification, particularly at high fundamental frequencies. Actually, vowel identification is almost impossible above 700 Hz (pitch F5). Another great difference between vocal sound produced in speech and the classical singing tradition concerns female voices, which need to reduce the timbral differences between voice registers. Females normally speak in modal or chest register, and the transition to falsetto tends to happen somewhere above 350 Hz. The great timbral differences between these registers are avoided by establishing control over the register function, that is, over the vocal fold vibration characteristics, so that seamless transitions are achieved. In many other respects, there are more or less close similarities between speech and singing. Thus, marking phrase structure, emphasizing important events, and emotional coloring are common principles, which may make vocal artists deviate considerably from the score’s nominal description of fundamental frequency and syllable duration.

Objectives We determined the effectiveness of calcium hydroxylapatite (CaHA) paste in vocal rehabilitation. Methods We examined a retrospective case series of 39 adult patients who underwent CaHA paste injection for vocal fold rehabilitation over a 5-year period. The outcomes included the change in the Voice Handicap Index (VHI) score; procedure-related complications; and the need for follow-up voice procedures. Results The VHI scores demonstrated overall improvement, with a decrease from the preoperative mean of 61.2 ± 24.0 to a postoperative mean of 35.9 ± 26.3 (p = 0.0001) after a mean follow-up time of 17.8 ± 13.6 months. The procedure was more likely to succeed in patients with paralysis and/or paresis than in patients with glottic soft tissue defects. After injection, the VHI scores worsened in 3 of 7 patients (43%) in the soft tissue defect group, compared to only 2 of 28 (7%) in the paralysis and/or paresis group (p = 0.04). Four of 7 patients with soft tissue defects (57%) required secondary vocal procedures to improve the voice, compared to only 2 of 32 (6%) in the paralysis and/or paresis group (p = 0.006). Conclusions Injection of CaHA paste results in significantly improved vocal scores in the majority of patients. Use of the paste was less satisfactory in patients with soft tissue defects because of poor retention of the paste in the scarred vocal fold remnant.

Symptomatic unilateral laryngeal paralysis may be treated successfully by a wide variety of surgical techniques. These techniques share the concept that stabilization of the paralyzed vocal fold in a median position will improve glottic function. Medialization laryngoplasty with expanded polytetrafluoroethylene (ePTFE) incorporates the general principles of established medialization procedures, yet is unique in its simplicity. The technique does not require special instrumentation, employs incremental adjustment of vocal fold position, and utilizes an implantable material with a long history of patient safety. We describe this new technique and report on the outcome of our first 16 patients treated. No surgical or implant-related complications have occurred. Voice results were measured from preoperative and postoperative video and voice recordings by four independent observers using a standardized assessment tool. Voice grade and breathiness were evaluated on a four-point scale (0 = normal and 3 = abnormal, extreme). The mean overall grade improved from 2.3 ± 0.6 to 1.1 ± 0.6, and breathiness from 2.0 ± 0.8 to 0.4 ± 0.4. The technique is simple, the implant material has been in clinical use for decades, and the voice results are good to excellent.

Sixteen patients with paralytic dysphonia were treated with Teflon injection in the paralyzed vocal fold. Trained voice pathologists rated the pre- and postinjection voices on a 5-point scale for each of 11 voice characteristics. Among these, aphonia, breathiness, and hypofunction diminished significantly after injection. The perceptual evaluation was correlated with acoustic data from long-time-average spectrum analysis, fundamental frequency distribution analysis, and waveform perturbation analysis. In this acoustic assessment, systematic changes were found in the long-time-average spectra, which agreed well with the perceptual data. In 12 of 16 patients the voice was both perceptually and acoustically improved after Teflon injection.

Selection Of

In recent times, vocal fold problems have been increasing dramatically due to unhealthy social habits and voice abuse. Non-invasive methods like acoustic analysis of voice signals can be used to investigate such problems. Various feature extraction techniques are used to classify the voice signals into normal and pathological. Among them, long-time acoustical parameters are used by many researchers. The selection of best long-time acoustical parameters is very important to reduce the computational complexity, as well as to achieve better accuracy with minimum number of features. In order to select best long-time acoustical parameters, different feature reduction methods or feature selection methods are proposed by researchers. In this work, genetic algorithm (GA) based optimal selection of long-time acoustical parameters is proposed to achieve higher accuracy with minimum number of features. The classification is carried out using k-nearest neighbourhood (k-NN) classifier. In comparison with other works in the literature, the simulation results show that a minimum of 5 features are required to classify the voice signals by GA and a better accuracy of 94.29% is achieved.
