Deep learning-based approaches have demonstrated promising performance for speech enhancement (SE) tasks. However, these approaches generally require large quantities of training data and computational resources for model training. An alternate hierarchical extreme learning machine (HELM) model has been previously reported to perform SE and has demonstrated satisfactory results with a limited amount of training data. In this study, we investigate application of the HELM model to improve the quality and intelligibility of bone-conducted speech. Our experimental results show that the proposed HELM-based bone-conducted SE framework can effectively enhance the original bone-conducted speech and outperform a deep denoising autoencoder-based bone-conducted SE system in terms of speech quality and intelligibility with improved recognition accuracy when a limited quantity of training data is available.

Abstract

Deep learning-based approaches have demonstrated promising performance for speech enhancement (SE) tasks. However, these approaches generally require large quantities of training data and computational resources for model training. An alternate hierarchical extreme learning machine (HELM) model has been previously reported to perform SE and has demonstrated satisfactory results with a limited amount of training data. In this study, we investigate application of the HELM model to improve the quality and intelligibility of bone-conducted speech. Our experimental results show that the proposed HELM-based bone-conducted SE framework can effectively enhance the original bone-conducted speech and outperform a deep denoising autoencoder-based bone-conducted SE system in terms of speech quality and intelligibility with improved recognition accuracy when a limited quantity of training data is available.
