A novel stereophonic noise reduction method is proposed based upon a combination of cascaded subspace filters, with delay and advancing elements alternatively inserted between the adjacent cascading stages, and two-channel adaptive signal enhancers. Simulation results based upon real stereophonic speech contaminated by two correlated noise components show that the proposed method gives improved...

The measurement of the impact of skin diseases on patients' quality of life is important. This review explains the reasons for this, explains the main methods of measuring quality of life in dermatology and describes recent research in this area. Virtually all aspects of patients' lives can be affected by skin disease. It is important to be able to measure this effect for clinical, therapeutic ...

When users access information from text, they engage in strategic fixation, visually scanning the text to focus on regions of interest. However, because speech is both serial and ephemeral, it does not readily support strategic fixation. This paper describes two design principles, indexing and transcript-centric access that address the problem of speech access by supporting strategic fixation. ...

Three experiments are reported that use new experimental methods for the evaluation of text-to-speech (TTS) synthesis from the user’s perspective. Experiment 1, using sentence stimuli, and Experiment 2, using discrete ‘‘call centre’’ word stimuli, investigated the effect of voice gender and signal quality on the intelligibility of three concatenative TTS synthesis systems. Accuracy and search t...

Although jitter, shimmer, and turbulent noise characterize all voice signals, their perceptual importance has not been established psychoacoustically. To determine which of these acoustic attributes is important in listeners’ perceptions of pathologic voices, listeners used a speech synthesizer to adjust levels of jitter, shimmer, and noise so that synthetic voices matched natural pathological ...

The current study presents findings from a mixed-methods study of investigating the self-regulatory role of private speech (self-talk) on students’ translation quality. The aim of the study was to validate the adapted version of a self-verbalization questionnaire. The construct validity and reliability of the scale were supported by the CFA which revealed that all items reached the acceptable f...

This paper aims to investigate performance analysis and enhancements for the adaptive algorithms in speech enhancement and develop refined algorithms. The speech signal may get corrupted due to different types of noise. Hence, it becomes a challenge to maintain its high quality [2]. Noise Cancellation is a technique used for reducing undesired noise signal. Communication has become an integral ...

background: unsustainable development of human societies, especially in arid and semi-arid areas, is one of the most important environmental hazards that require preservation of groundwater resources, and permanent study of qualitative and quantitative changes through sampling. accordingly, this research attempts to assess and analyze the spatial variation of quantitative and qualitative indica...
