Introduction: Laryngopharyngeal reflux (LPR) is considered an important cause of voice disorder. We aimed to determine the frequency of LPR in patients with voice disorder and the association between Koufman Reflux Symptom Index (RSI), Reflux Finding Score (RFS), gastroesophageal reflux disease (GERD), and proximal acid reflux in these patients. Materials and Methods: We performed a prospective...

One of the most important human abilities is speech along with hearing. Speech is the primary way in which we attune to the society. Our voice can uncover several information about us to other people. It reveals our energy level, our emotions, our personality and our artistry. Voice abnormalities may cause social isolation or may create problems in the professional field. Due to this significan...

Intonation, when used in a narrow sense, refers to fundamental frequency (henceforth F0) patterns in speech that convey information beyond lexical meanings. In a broader sense, intonation also includes other suprasegmental patterns such as duration, intensity and voice quality, etc., that also convey non-lexical meanings. This article will focus mainly on the former, because, as will be seen, F...

This is a summary of variabilities and co-variation of prosodic parameters found in our studies of text reading and in the development of text-to-speech synthesis. In addition to F0, duration and intensity, the survey includes aspects of voice production and perception. The role of sub-glottal pressure is discussed. Speech parameters have been correlated with our continuously graded prominence ...

Based on German production data from the ‘Kiel Corpus of Spontaneous Speech’, we conducted two perception experiments, using an innovative interactive task in which participants gave real oral responses to resynthesized question stimuli. Differences in the time interval between stimulus question and response show that segmental reduction, intensity level, and the shape of the phrase-final rise ...

objectives: nasality is one of the important parameters in pathology of voice resonance. voice of normal adults has nasality to some extent. it appears that nasality, like other parameters of voice, can be affected by loudness which can be measured in experimental evaluations. this study was conducted to determine the effect of vocal loudness on nasalance of vowels in normal adults and to ident...

Speech therapy aiming at improving voice quality and speech intelligibility is often hampered by the lack of knowledge of the underlying deficits. One way to help speech therapists treating patients would be to supply synthetic benchmarks for pathological speech. These can be used to train therapists and evaluate and interpret automatic speech recognizers used for diagnosing pathological speech...

Seeing that speakers increase the intensity of their voice when speaking in loud noise (Lombard effect), this paper proposes a speech transformation approach to mimic this Lombard effect for improving the intelligibility of speech in noisy environments. The approach attempts to simulate the variations of duration, formant frequencies, formant bandwidth, fundamental frequency (F0), and energy in...

Sensory-substitution prosthetic systems are based on the idea of substituting visual stimulation with stimulation from another intact sense such as audition or touch. Although such systems have been studied for almost 40 years (Bach-y-Rita 1968), they are still poorly understood. Here we ask whether we learn to perceive simple spatial properties using The vOICe (Meijer 1992), a system for visua...
