Spectrum reconstruction for automatic speech recognition
Jean Laroche,Jordan Cohen +1 more
TL;DR: In this article, transform domain reconstruction of noise-corrupted portions of an acoustic signal to emulate speech which is obscured by the noise replacement transform values for the noise corrupted portions are determined utilizing the portions of the acoustic signal which contain speech.
Journal Article
On the Stability of Time-Varying Recursive Filters
TL;DR: In this paper, the problem of the bounded-input/bounded-output stability of time-varying recursive filters is discussed, and two simple criteria based on the state transition matrix can be derived that guarantee the stability of the time-evariant filter.
Patent
Method for enhancing audio signals
TL;DR: In this paper, a frequency band of an audio input signal is analyzed to determine if a transient is present. When transients are detected, modifications are made to the intensity levels corresponding to the frequency band for a brief time period.
Patent
Synthesis of time-domain signals using non-overlapping transforms
TL;DR: In this paper, a template is determined for the selected sinusoid based on the computed parameter values and a selected window function and the template is added to a frequency-domain frame.

A dynamic programming approach to audio segmentation and speech/music discrimination
M.M. Goodwin,Jean Laroche +1 more
TL;DR: The design of the dynamic program cost functions is considered; the algorithm is able to derive effective cost functions without relying on significant prior information about the structure of the expected data clusters.
