Objective speech quality measures, informal listening tests, and the results of automatic speech recognition experiments indicate a substantial benefit from AMS-based noise suppression, in comparison to unprocessed noisy speech.

Stern, Robust Recognition rates of the modern speech recognition systems are highly dependent on background noise levels and a choice of acoustic feature extraction method can have a significant impact on system performance. This paper presents a robust speech recognition system based on a front-end motivated by human cochlear processing of audio signals.

We describe an FFT-based companding algorithm for preprocessing speech before recognition. The algorithm mimics tone-to-tone suppression and masking in the auditory system to improve automatic speech recognition performance in noise.
We describe an FFT-based companding algorithm for preprocessing speech before recognition. Moreover, it is also very computationally efficient and suited to digital implementations due to its use of the FFT.
For speech processing of meetings we cannot assume uniformly distributed noise or xed speaker position over the entire duration of the meeting. Speaker localisation is therefore a necessary component of meeting analysis
For speech processing of meetings we cannot assume uniformly distributed noise or xed speaker position over the entire duration of the meeting. Speaker localisation is therefore a necessary component of meeting analysis. The primary goal of a speaker (or source) localisation system is accuracy.

Finally, we also discuss several issues concerning the use of signal processing algorithm based on models of the human auditory periphery, which so far have not yet provided substantial quantitative reductions in recognition error rate.
Speech recognition in noisy conditions is a major challenge for computer systems, but the human brain performs it routinely and accurately
Speech recognition in noisy conditions is a major challenge for computer systems, but the human brain performs it routinely and accurately. Automatic speech recognition (ASR) systems that are inspired by neuroscience can potentially bridge the performance gap between humans and machines. We present a system for noise-robust isolated word recognition that works by decoding sequences of spikes from a population of simulated auditory feature-detecting neurons.
Robust Distributed Speech Recognition Using Auditory Modelling. The features that represent the speech are sent by means of an error protected data channel to the classifier for processing. By Ronan Flynn and Edward Jones. Home Books Modern Speech Recognition Approaches with Case Studies. DSR avoids both the speech encoding and decoding stages associated with centralised recognition and so eliminates the degradations that originate from the speech compression algorithms.
New Era for Robust Speech Recognition: Exploiting Deep Learning. This book provides a comprehensive overview of the recent advancement in the field of automatic speech recognition with a focus on deep learning models including deep neural networks and many of their variants. This is the first automatic speech recognition book dedicated to the deep learning approach. In addition to the rigorous mathematical treatment of the subject, the book also presents insights and theoretical foundation of a series of highly successful deep learning models.
