Abstract / Description of output
Speech playback is harder to understand in noise. Near End Listening Enhancement algorithms try to overcome the problem by enhancing the speech signal before it is played by a device. Different strategies have been tried, achieving variable degrees of success in specific noise conditions. Such technologies, however, are often tested in artificial settings - with controlled noise sources and no reverberation. The purpose of this study is to compare a set of state-of-the-art algorithms based on different approaches (adaptive vs non-adaptive, with or without a compensation for reverberation) in simulated real- life scenarios. Binaural noise recordings and impulse responses of real environments have been used to create two representative scenarios in which speech playback may occur, namely a domestic and a public space. A preliminary study with N=24 subjects revealed the need for higher SNRs in the realistic settings (in comparison to controlled noise conditions) in order to obtain the same levels of intelligibility for plain speech. The goal of the main study is to assess the impact of noise adaptivity and reverberation awareness in realistic scenarios, in order to better understand how to make speech playback more robust to noise in real-life situations.
