The main objective of this paper is to explore the effectiveness of perceptual features for performing isolated digits and continuous speech recognition. The proposed perceptual features are captured and code book indices are extracted. Expectation maximization algorithm is used to generate HMM models for the speeches. Speech recognition system is evaluated on clean test speeches and the experimental...
In this paper we introduce the SPHINX3-based Bengali Automatic Speech Recognition(ASR) system Shruti-II and an E-mail application based on it. This ASR system converts standard Bengali continuous speech to Bengali Unicode. Due to the limited availability of access to computer, visually impaired community can use speech as an input method for various computer-based application. This paper also demonstrates...
According to HMM's strong representation capability of speech signal and GMM's better transformation effect, a method for LSF conversion using HMM combined with GMM is proposed. The theoretical derivation and flow diagram of this algorithm are offered, and gauss model is introduced to achieve the prosodic features transformation. The experiment is applied on two segment speech, and the result reveals...
