In contrast with for example audiovisual speech, the relation between visual and auditory properties of letters and speech sounds is artificial and learned only by explicit instruction. The arbitrariness of the audiovisual link together with the widespread usage of letter-speech sound pairs in alphabetic languages makes those audiovisual objects a unique subject for crossmodal research. Brain i...

introduction: the every possible attempt in voice disorders assessment is to gather samples which represent individual s’ actual voice in the daily speech. the researchers have found that voice characteristics in reading a passage are closer to daily speech. making texts has been started since early 20th century. the lack o f suitable text in farsi language makes it difficult to conduct requisi...

Voice-mail and video-mail systems for the Internet are becoming very popular, because the speech and video compression technology is greatly improved in these days. Asynchronous voice-mail system, however, does not seem attractive because it's not designed for discussions. We propose a network-based voice conference system which enables asynchronous and bi-directional discussions. The system di...

This paper describes the use of denoising techniques in the time domain applied to the outputs of filters corresponding to a Multi Resolution Analysis. The fact that energies of denoised samples are used for Automatic Speech Recognition (ASR) makes soft thresholding particularly attractive especially if Principal Component Analysis (PCA) is applied to the whole tree of energy features. This con...

Speaker verification based on phone modelling is examined in this paper. Phone modelling is attractive, because different phonemes have different levels of usefulness for speaker recognition, and because phone modelling essentially makes a speaker verification algorithm text independent. The speaker verification system used here is based on a two stage approach, where speech recognition (segmen...
