Previously, we proposed a speaker recognition system using a combination of MFCC-based vocal tract feature and phase information which includes rich vocal source information. In this paper, we investigate the efficiency of combination of various vocal tract features (MFCC and LPCC) and vocal source features (phase and LPC residual) for normal-duration and short-duration utterance. The Japanese ...

In laryngeal paralysis, the stiffness of the denervated vocal fold is decreased. This leads to deviant vibratory patterns involving 2 asymmetric vocal folds and results in abnormal vocal quality. Follow-up studies of medialization thyroplasty patients have noted that decrement in vocal quality after medialization is often because of continuing vocal fold atrophy. Vocal cord atrophy from denerva...

A 49-year-old female presented with an aggressive pelvic angiomyxoma (AAM). The completely resected specimen revealed the usual myxedematous tumor with a nodule inside it. Histopathologically, the myxedematous area consisted of bland spindle-shaped cells in the background of blood vessels of varying calibers, and the nodule was composed of tumor cells with epithelioid features. In the nodule, c...

PVA roller brushes are widely used for cleaning after the CMP process, one of semiconductor manufacturing processes. The brush features protrusions called nodules and rotates on wafer in cleaning. This article introduces a model that uses to remove nanoscale impurities. evanescent fields prism enable us observe contact behavior clarify there is little volume near surface during sliding. We clas...

OBJECTIVES/HYPOTHESIS This study intends to objectively quantify and compare the regression rates of vocal lesions in patients receiving either vocal fold steroid injection (VFSI) or vocal hygiene education (VHE). Potential influence of occupational vocal demands on the treatment outcome was also investigated. STUDY DESIGN Retrospective case series. METHODS This study enrolled 176 patients ...

Songbirds are one of the few groups of animals that learn the sounds used for vocal communication during development. Like humans, songbirds memorize vocal sounds based on auditory experience with vocalizations of adult "tutors", and then use auditory feedback of self-produced vocalizations to gradually match their motor output to the memory of tutor sounds. In humans, investigations of early v...

Juvenile xanthogranuloma (JXG) is a benign manifestation of non-Langerhans cell histiocytosis characterized by yellowish cutaneous nodules. Its occurrence in the larynx is very rare, but laryngeal JXG may cause severe respiratory distress. We report a patient with isolated laryngeal JXG treated by laryngomicrosurgery, and this is the first report of JXG extending to vocal fold. A 3-year-old gir...

OBJECTIVE To identify the relationship between vocal self-assessment, the assessment of voice by a speech-language pathologist (SLP), and the effect of voice on the quality of life of patients with benign thyroid diseases. STUDY DESIGN Cross-sectional study. SETTING University hospital. SUBJECTS AND METHOD A total of 67 women with a mean age of 44.7 ± 14.8 years and a diagnosis of benign ...

BACKGROUND In our daily experience, the differentiation between a cold and hot nodule is a very important factor for further clinical management of the patient. In this study, we compared the characteristics of incidentally found thyroid nodules detected on computed tomography (CT) to thyroid scintigraphy (TS). METHODS Diagnostic reports from chest CT with intravenous contrast and TS examinat...

OBJECTIVES To review the Early Lung Cancer Action Project experience and the medical literature from 1993 to 2003 on detection of the small, noncalcified pulmonary nodule by CT in order to formulate a management algorithm for these nodules. DESIGN Prospective noncomparative study of smokers without prior malignancy and a review of the medical literature of CT screening of lung cancer. INTER...
