Two studies are presented, in which emotional vocal recordings were made using a computer emotion induction task and an imagination technique. Concurrent recordings were made of a variety of physiological parameters, including electroglottograph, respiration, electrocardiogram, and surface electromyogram (muscle tension). Acoustic parameters pertaining to voice quality, including F0 floor, F0 r...

Voice mimic systems using articulatory codebooks require an initial estimate of the vocal tract shape in the vicinity of the global optimum. For this purpose, we need to gather a large set of corresponding articulatory and acoustic data in the articulatory codebook. Thus, searching and accessing the codebook becomes a di cult task. In this paper, the design of an articulatory codebook is presen...

Low transmission of heat is one of the major problems for heat exchanger fluids in many industrial and scientific applications. This includes cooling of the engines, high power transformers to heat exchangers in solar hot water panels or in refrigeration systems. In order to tackle these problems in thermal industries, nanofluids could play a significant role as excellent heat exchanger materia...

diesel exhaust particles are a complex mixture of thousands of gases and fine substances that contain more than 40 different environmental contaminants. being exposed to these exhaust particles (called soot) can cause lung damage and respiratory problems. diesel particulate filters are used in many countries for mobile sources as a legal obligation to decrease harmful effect of these fine parti...

This article discusses the use of phonetic features in automatic speech recognition. The phonetic features are derived from acoustic parameters by means of Kohonen networks. Behind the use of phonetic features instead of standard acoustic parameters lies the assumption that it is useful to help the system to focus on linguistically relevant signal properties. Previous experiments using very sim...

Two models of statistical dependence between acoustic model parameters of a large vocabulary conversational speech recognition (LVCSR) system are investigated for the purpose of rapid speakerand environment-adaptation from a very small amount of speech: (i) a Gaussian multiscale process governed by a stochastic linear dynamical system on a tree, and (ii) a simple hierarchical treestructured pri...

This paper presents a follow up of a study on the automatic detection of prosodic prominence in continuous speech. Prosodic prominence involves two different prosodic features, pitch accent and stress, that are typically based on four acoustic parameters: fundamental frequency (F0) movements, overall syllable energy, syllable nuclei duration and mid-tohigh-frequency emphasis. A careful measurem...

Background: speech acoustics. Aim: to acoustically analyze the substitution between /t/ and /k/ in the speech production of children with typical and deviant acquisition process in order to identify and quantify the presence of covert contrast. Method: the experiment involved the repetition of words that combined /t/ and /k/ with /a/ and /u/ in stressed position. Participants were 9 children di...
