Speech constitutes much of the communicated information; most other perceived audio signals do not carry nearly as much information. Indeed, much of the non-speech signals maybe classified as ‘noise’ in human communication. The process of separating conversational speech and noise is termed voice activity detection (VAD). This paper describes a new approach to VAD which is based on the Wavelet ...

In Emotion Recognition in Conversations (ERC), the emotions of target utterances are closely dependent on their context. Therefore, existing works train model to generate response utterance, which aims recognise leveraging contextual information. However, adjacent generation ignores long-range dependencies and provides limited affective information many cases. addition, most ERC models learn a ...

BACKGROUND Circulatory assist devices are applied to support patients with end-stage heart failure or circulatory collapse. Extracorporeal membrane oxygenation (ECMO) and ventricular assist device (VAD) are the two devices that are commonly used in these situations. However, in patients undergoing ECMO, complications occur more frequently and are more severe than in those with VAD, especially i...

In this paper, a voice activity detection (VAD) method is proposed based on Gaussian mixture models (GMMs) by exploiting the spatial selectivity in dual-microphone environments. In other words, each GMM is constructed according to the direction-ofarrival (DOA) to detect speech intervals. Based on the assumption that the target speech is located in front of dual-microphones, the VAD is performed...

Background: Vitamin A deficiency (VAD) is still a public health problem across the globe and also in Burkina Faso, especially for under-five-years-old children. Since less information is available about the prevalence of VAD among the primary school children, this study aimed to study this area. Methods: A randomised double-blind placebo-controlled trial was conducted to assess the effect of hi...

In jurisdictions where voluntary assisted dying (VAD) is legal, eligibility assessments, prescription and administration of a VAD substance are commonly performed by senior doctors. Junior doctors’ involvement limited to range more peripheral aspects patient care relating VAD. the Australian state Victoria, has been legal since June 2019, all health professionals have right under legislation co...

BACKGROUND Neuropsychiatric deficits can induce marked disability in patients with dementia and increase caregiver distress. Several studies have found that neuropsychiatric symptoms are common both in patients with Alzheimer's disease (AD) and patients with vascular dementia (VaD). However, there are few studies of the neuropsychiatric disturbances in large clinical samples of patients with mi...

BACKGROUND Disaster relief personnel tend to be exposed to excessive stress, which can be a cause of mental disorders. To prevent from mental disorders, frequent assessment of mental status is important. This pilot study aimed to examine feasibility of stress assessment using vocal affect display (VAD) indices as calculated by our proposed algorithms in a situation of comparison between differe...
