This paper report that the implementation of the speaker direction detector using a small and low-priced micro controller called ”dsPIC” and propose the speaker localization method integrating the results from the multiple detectors. To confirm a basic performance of the proposed method, an experiment for estimating 6 locations at intervals of 1m using a pair of the speaker direction detectors ...

in a voice conversion system speech signal of a speaker (i.e. source speaker) is modified so that it sounds as if it had been pronounced by b speaker (i.e. target speaker). this process, sometimes, is called speaker conversion (changing speaker identity). achieved signal from speaker conversion system is desired to have high quality and very natural. to satisfy this, three major methods are pro...

Ultrasound wave is a kind of waves with the frequency higher than the human audible frequency. Although ultrasound was first used for military identification purposes, it has been used for decades for various other applications, especially medical applications. Medical applications of ultrasound include diagnostic and therapeutic applications, such as for the treatment of cancer. In this paper,...

The acoustic aspects that differentiate voices are difficult to separate from signal traits that reflect the identity of the sounds. There are two sources of variation among speakers: (1) differences in vocal cords and vocal tract shape, and (2) differences in speaking style. The latter includes variations in both target vocal tract positions for phonemes and dynamic aspects of speech, such as ...

based on how formal a conversation is, how much familiar the speaker and the listeners are with each other and how distant is the speaker's social status from the listener's one, the speaker uses certain forms of language known as styles of language. linguistic styles are different from language varieties. selection of the styles depends on definite social situations and the kind of r...
