Symbolic vs. acoustics-based style control for expressive unit selection
نویسندگان
چکیده
The present paper addresses the issue of flexibility in expressive unit selection speech synthesis by using different style selection techniques. We select units from a mixed-style unit selection database, using either forced style switching, no control, symbolic target cost, or acoustic target cost as a style selection criterion. We assess the effect of selection technique, feature weight and relative weight of target vs. join costs on a set of objective measures for style specificity and smoothness.

متن کاملExpressive Speech Synthesis for Czech Limited Domain Dialogue System – Basic Experiments
This paper describes a development of limited domain expressive speech synthesis for the Czech language. Our current speech synthesis system is based on unit selection methods and produces high quality speech in a neutral speaking style. This work focuses on modifications made in the synthesis algorithm to integrate expressivity into generated speech. There is also introduced a listening test, ...
متن کاملExpressive Control of Singing Voice Synthesis Using Musical Contexts and a Parametric F0 Model
Expressive singing voice synthesis requires an appropriate control of both prosodic and timbral aspects. While it is desirable to have an intuitive control over the expressive parameters, synthesis systems should be able to produce convincing results directly from a score. As countless interpretations of a same score are possible, the system should also target a particular singing style, which ...
متن کاملSymbolic prosody driven unit selection for highly natural synthetic speech
In the effort to obtain synthetic speech with the quality near to natural, and potentially, to be able to build expressive synthesis, the unit selection approach has become very important. To increase the naturalness of our native TTS system ARTIC we employed the specific version of the approach. It is driven by the high–level symbolic prosody description, defined according to the phenomena of ...
متن کاملInvestigating HMMs as a parametric model for expressive speech synthesis in German
The paper investigates the potential of HMM based synthesis to support the parameterisation of expressive speech in German. First, we review the assets of HMMs in the perspective of previous works in speech modelling and speech transformation. It is shown that HMMs define a flexible parametric model of the speech acoustics, which readily integrates several levels of speech modelling, such as di...
