There has been considerable research into perceptible correlates of emotional state, but a very limited amount of the literature examines the acoustic correlates and other relevant aspects of emotion effects in human speech; in addition, the vocal emotion literature is almost totally separate from the main body of speech analysis literature. A discussion of… (More)
Modern speech synthesis systems with very high intelligibility are readily available in a number of languages. However, the output from all present systems is still readily identifiable as being machine-generated-the output does not sound "natural". One aspect of naturalness is the variability introduced by the emotional state of the speaker, and related… (More)
Mesenchymal stem/stromal cells (MSCs) can regenerate tissues by direct differentiation or indirectly by stimulating angiogenesis, limiting inflammation, and recruiting tissue-specific progenitor cells. MSCs emerge and multiply in long-term cultures of total cells from the bone marrow or multiple other organs. Such a derivation in vitro is simple and… (More)
Applying an analysis of acted vocal emotions to improve the simulation of synthetic speech. Abstract: All speech produced by humans includes information about the speaker, including conveying the emotional state of the speaker. It is thus desirable to include vocal affect in any synthetic speech where improving the naturalness of the speech produced is… (More)
A system for producing synthetic speech which incorporates vocal emotion effects has been developed. This has been incorporated into a communication prosthesis for non-vocal people to give them more freedom of expression via a synthetic voice. A range of common emotions can be simulated by the system.
Mesenchymal stem/stromal cells (MSCs) and MSC-like multipotent stem/progenitor cells have been widely investigated for regenerative medicine and deemed promising in clinical applications. In order to further improve MSC-based stem cell therapeutics, it is important to understand the cellular kinetics and functional roles of MSCs in the dynamic regenerative… (More)
