Let f(n) be a sampled voice signal. Our goal is to identify the voiced (V) portions of f (as opposed to the silence (S) and unvoiced (UV) portions). In the following discussion, the sampling rate is 22050 Hz, quantized at 8 bits. A window of length of 880 is twice the maximum period of the minimum frequency of 50 Hz we will track in the time domain. We use the algorithm described below to provi...

Mannion and Davies' article recognises whistleblowing as an important means of identifying quality and safety issues in healthcare organisations. While 'voice' is a useful lens through which to examine whistleblowing, it also obscures a shifting pattern of uncertain 'truths.' By contextualising cultures which support or impede whislteblowing at an organisational level, two issues are overlooked...

In the healthcare context, whistleblowing has come to the fore of political, professional and public attention in the wake of major service scandals and mounting evidence of the routine threats to safety that patients face in their care.

Preprocessing of speech signals is considered a crucial step in the development of a robust and efficient speech or speaker recognition system. In this paper, we present some popular statistical outlier-detection based strategies to segregate the silence/unvoiced part of the speech signal from the voiced portion. The proposed methods are based on the utilization of the 3 σ edit rule, and the Ha...
