N2 - This paper introduces a new approach to speech noises analysis and synthesis. The different types of speech noises are reviewed together, with their first order statistics. A theoretical framework is formulated for speech noises analysis in terms of time-frequency energy concentrations (spectral peaks, amplitude and phase modulation). This framework is based on the linear acoustic theory of speech production, and on the theory of random modulation. A synthesis scheme using random timed wavelets is proposed. It is based on the statistical properties of shot noise. Experiment,al results on synthesis of speech noises are given.
