the role of orthography in difficult speech perception tasks has already been proved (dehaene & cohen, 2011). since the processing of heterographic homophones is believed to be more difficult than other words (hino & colleagues, 2013), the present study aimed at identifying the role of orthography and word forms in perception of such words during top-down processes, such as speech perception. a...

storaging or transmission of speech signals at very low bit rate is a hot area in the field of speech processing. we used stochastic inter-frame interpolators and vector quantization (vq) as a new method for developing a high quality 1200 bps speech vocoder. the objective and subjecgtive test results show that performance of the new vocoder is compairable with 4800 bps standard vocoders (as celp).
