Twenty-three formulas, closely related to Dixon's theorem in the theory of the generalized hypergeometric series, are obtained. Twenty-six limiting cases are also deduced.
ManyEars is an open framework for microphone array-based audio processing. It consists of a sound source localization, tracking and separation system that can provide an enhanced speaker signal for improved speech and sound recognition in real-world settings. ManyEars software framework is composed of a portable and modular C library, along with a graphical… (More)
This paper presents WISS, a speaker identification system for mobile robots integrated to ManyEars, a sound source localization, tracking and separation system. Speaker identification consists in recognizing an individual among a group of known speakers. For mobile robots, performing speaker identification in presence of noise that changes over time is one… (More)
Localization of sound sources in adverse environments is an important challenge in robot audition. The target sound source is often corrupted by coherent broadband noise, which introduces localization ambiguities as noise is often mistaken as the target source. To discriminate the time difference of arrival (TDOA) parameters of the target source and noise,… (More)
BACKGROUND The Canadian Cardiology Society recommends that patients should be seen within 2 weeks after an emergency department (ED) visit for heart failure (HF). We sought to investigate whether patients who had an ED visit for HF subsequently consult a physician within the current established benchmark, to explore factors related to physician… (More)
To be used on a mobile robot, speech/non-speech discrimination must be robust to environmental noise and to the position of the interlocutor, without necessarily having to satisfy low-latency requirements. To address these conditions, this paper presents a speech/non-speech discrimination approach based on pitch estimation. Pitch features are robust to… (More)
Sound source localization is an important challenge for mobile robots operating in real life settings. Sound sources of interest, such as speech, are often corrupted by broadband coherent noise sound source(s) that are non-stationary during transitions between steady-state segments. The interfering noise introduces localization ambiguities leading to the… (More)
