Intonation Atom Based Emphasis Transfer
نویسندگان
چکیده
Speech to speech translation can benefit from translation of emphasis. We propose to use an intonation model to retrieve and transfer events associated with emphasis in the intonation. This model decomposes the F0 contour into basic intonation atoms using the matching pursuit algorithm. We investigate the role of these components in the perception of emphasis. Some of the most prominent local components are used to convert a neutral sentence to a sentence with emphasis on a specific word. The method is evaluated using parallel emphatic speech in the same language and listening tests are conducted to validate its efficacy. The results show that our intonation based approach to emphasis transfer elicits emphasis perception in neutral speech.

Weighted correlation based atom decomposition intonation modelling
Intonation modelling is an integral part of text-to-speech systems from their very beginnings. This has led to the proliferation of various intonation models, each with its own relative strengths and weaknesses. Only a few of these intonation models are based on physiology, despite the advantage that such models are language independent. We propose a new intonation model inspired by the physiol...
متن کاملUnified Prosody Model based on Atom Decomposition for Emphasis Detection
The prosody of the speech signal carries both linguistic and paralinguistic information. As such, there is a necessity of its modelling for the purpose of integrating it in speech technology systems. So far, there has been a multitude of proposed models focusing mainly on intonation, but a few also on energy and duration. The paper proposes an integrated approach to modelling the three dimensio...

متن کاملEmphasis recreation for TTS using intonation atoms
We are interested in emphasis for text to speech synthesis. In speech to speech translation, emphasising the correct words is important to convey the underlying meaning of a message. In this paper, we propose to use a generalised command-response (CR) model of intonation to generate emphasis in synthetic speech. We first analyse the differences in the model parameters between emphasised words i...
متن کاملIntonation modelling using a muscle model and perceptually weighted matching pursuit
We propose a physiologically based intonation model using perceptual relevance. Motivated by speech synthesis from a speech-to-speech translation (S2ST) point of view, we aim at a language independent way of modelling intonation. The model presented in this paper can be seen as a generalisation of the command response (CR) model, albeit with the same modelling power. It is an additive model whi...
