摘要:基于語音狀態模型的語音增強算法是當前語音信號處理的研究熱點。把通常的LPC語音模型修正后,將得到兩個語音模型:時變AR 模型、時變雙AR模型。但是利用這些模型增強語音時,都沒有考慮到語音的清音、濁音區別。為此本文引入了語音清濁音狀態空間模型,這種模型在描述語音方面比時變AR模型、時變雙AR模型要強,而且物理含義明顯 同時在用含噪語音信號預測純凈語音信號時,引入遺忘因子和粒子濾波算法以降低計算復雜性,減小運算量。實驗證明,增強后的語音信號信噪比有一定提高.且優于傳統的LPC模型.

TOOL (Tiny Object Oriented Language) is an easily-embedded, object-oriented, C++-like-language interpreter. The language, and indeed a significant part of the core of the TOOL engine, is based on the BOB project, a work that was originally developed by David Betz covered in previously published issues of Dr. Dobb s Journal.
