Abstract       This paper presents a phoneme recognition method based on distinctive phonetic
               features (DPFs). The method comprises three stages. The first stage extracts 3 DPF
               vectors of 15 dimensions each from local features (LFs) of an input speech signal
               using three multilayer neural networks (MLNs). The second stage incorporates an
               Inhibition/Enhancement (In/En) network to obtain more categorical DPF
               movement and decorrelates the DPF vectors using the Gram-Schmidt
               orthogonalization procedure. Then, the third stage embeds acoustic models (AMs)
               and language models (LMs) of syllable-based subwords to output more precise
               phoneme strings. The proposed method provides a higher phoneme correct rate
               as well as phoneme accuracy with fewer mixture components in hidden Markov
               models (HMMs).
