This paper explores the use of micro-prosody in improving the quality of synthesised speech in concatenated text to speech synthesis (TTS) systems. Micro-prosody are defined as prosodic signals within context-dependent triphone units and across neighbouring triphones. Micro-prosody parameters are modelled using a Markovian model whose state distributions depend on the current linguistic-prosodi...

Human perceptions of speaker characteristics, needed to perform automatic predictions from speech features, have generally been collected by conducting demanding in-lab listening tests under controlled conditions. Concurrently, crowdsourcing has emerged as a valuable approach for running user studies through surveys or quantitative ratings. Micro-task crowdsourcing markets enable the completion...

a parallel hybrid system of hmm and gmm modeling techniques was implemented and used in a telephony speaker verification and identification system. spectral subtraction and weighted projection measure were used to render this system more robust against additional noise. cepstral mean subtraction method was also applied for the compensation of convolution noise due to transmission channel degrad...

Speaker verification from talking a few words of sentences has many applications. Many methods as DTW, HMM, VQ and MQ can be used for speaker verification. We applied MQ for its precise, reliable and robust performance with computational simplicity. We also used pitch frequency and log gain contour for further improvement of the system performance.

This paper proposes a new spectral estimation method for automatic speech recognition. The spectrum estimated with the conventional data window of around 30 ms shows harmonic structure in the voiced portions of speech data. The harmonic frequency interval is often comparable to the formant frequency interval for female voices with high F0, which results in spectral estimation error. The new ide...

Piezoelectric MEMS microspeakers are promising candidates for miniaturized speakers, such as in-ear applications. Using lead-free scandium doped aluminium nitride (ScAlN) thin film instead of lead zirconium titanate helps these speakers to be environmental friendly, CMOS compatible and potentially more linear. The piezoelectric coefficient ScAlN is higher than undoped AlN, which leads improved ...

The micro-time context of group processes (such as argumentation) can affect a group’s micro-creativity (new ideas). Eighty high school students worked in groups of four on an algebra problem. Groups with higher mathematics grades showed greater microcreativity, and both were linked to better problem solving outcomes. Dynamic multilevel analyses of the groups’ 2951 turns of conversation statist...
