OBJECTIVES It has been decided to identify the most frequent diseases of the larynx in people occupationally exposed to a considerable voice load and to assess the feasibility of using videostroboscopy to diagnose voice disorders and their organic effects in order to improve the reliability of certification of occupational vocal organ diseases as well as to evaluate the functioning of new regul...

Vocal control systems have been identified in all major groups of jawed vertebrates. Although steroid hormones are instrumental in the long-term development and maintenance of neural structures underlying vocalization, it is unknown whether steroids rapidly modulate the neural activity of vocal motor systems. The midshipman fish generates advertisement and agonistic calls that mainly differ in ...

Sperm whales (Physeter macrocephalus) are unusual in that there is good evidence for sympatric populations with distinct culturally determined behaviour, including potential acoustic markers of the population division. In the Pacific, socially segregated, vocal clans with distinct dialects coexist; by contrast, geographical variation in vocal repertoire in the Atlantic has been attributed to dr...

This study aims at investigating the interface between emotion and intonation patterns (more specifically, duration and pitch amplitude of speech). To this end, the acoustic properties of spectral parameters related to speech prosody are investigated. The results of acoustic and Statistical analysis show that mean level and range of FO in the contours vary strongly as a function of the degree o...

The authors investigated indication for phonosurgery for treatment of unilateral vocal fold paralysis based on laryngeal tomographs taken during sustained phonation of the vowel/u/, using a computed radiography system. As pre-operative quantitative indices, the thickness ratio (the ratio of the frontal sectional area of the paralyzed vocal fold to that of the other side, TR) and the level diffe...

Key words: swimming, diving, moving in 3 dimensions, mimicking, song, dance, prosody, articulate language, semi-aquatic past. Articulate language depends on very different abilities, such as vocal dexterity, vocal mimicking and the acquirement by children of the very different and arbitrary phonology and grammatical structure of any language. A vast array of experiments confirm that children ac...

This paper presents a statistical method that estimates a sequence of discrete musical notes from a temporal trajectory of vocal F0s. Since considerable effort has been devoted to estimate the frame-level F0s of singing voices from music audio signals, we tackle musical note estimation for those F0s to obtain a symbolic musical score. A naı̈ve approach to musical note estimation is to quantize t...

For quantifying vocal load over extended periods of time in real-life situations, the best adapted tools are voice dosimeters or voice accumulators. Such devices measure the frequency (F0), the intensity (SPL) and the duration of speech occurrences, generally using an accelerometer attached to the base of the neck. Growing attention has been focused on evaluating patterns of vocal behavior beca...

Introduction: Unilateral vocal cord paralysis (UVCP) is not an uncommon finding. Several procedures are available to manage glottal insufficiency. We conducted a clinical trial to evaluate the outcome of fat injection laryngoplasty.   Materials and Methods: Liposuctioned lower abdomen fat was injected for augmentation of paralyzed vocal cord in 20 patients with UVCP. Autologous fat was harveste...

A two-part study examined recognition of speech produced in quiet and in noise by normal hearing adults. In Part I 5 women produced 50 sentences consisting of an ambiguous carrier phrase followed by a unique target word. These sentences were spoken in three environments: quiet, wide band noise (WBN), and meaningful multi-talker babble (MMB). The WBN and MMB competitors were presented through in...
