The tilt intonation model
نویسنده
چکیده
The tilt intonation model facilitates automatic analysis and synthesis of intonation. The analysis algorithm detects intonational events in F0 contours and parameterises them in terms of the continuously varying Tilt parameters. We describe the analysis system and give results for speaker independent spontaneous dialogue speech. We then describe a synthesis algorithm which can generate F0 contours given a tilt parameterisation of an utterance. We give results showing how well the automatically produced contours match natural ones. The paper concludes with a discussion of the linguistic relevance of the tilt parameters and show that this is both a useful and natural way of representing intonation.

Analysis and synthesis of intonation using the Tilt model.
This paper introduces the Tilt intonational model and describes how this model can be used to automatically analyze and synthesize intonation. In the model, intonation is represented as a linear sequence of events, which can be pitch accents or boundary tones. Each event is characterized by continuous parameters representing amplitude, duration, and tilt (a measure of the shape of the event). T...
متن کاملUsing decision trees within the tilt intonation model to predict F0 contours
This paper presents an intonation generation system for use in a text-to-speech synthesis system. The intonation generation system uses classification trees to predict intonation event location and regression trees to predict parameters relating to the F0 shape for the predicted events. The decision trees model intonation within the Tilt intonation model, which provides a parameterized descript...

This paper has done a study and experimental analysis on different intonation events of Assamese speech. Assamese is a North East Indian language and spoken by lacks of people in India. The researchers need intonation model to identify language specific intonation events, which are necessary for synthesis process of that particular language. The paper shows outcomes of some experiments done wit...
متن کاملThe Function of Pitch Range Variations in Samples of Emotional Expressions in Persian
This study aims at investigating the interface between emotion and intonation patterns (more specifically, duration and pitch amplitude of speech). To this end, the acoustic properties of spectral parameters related to speech prosody are investigated. The results of acoustic and Statistical analysis show that mean level and range of FO in the contours vary strongly as a function of the degree o...
متن کاملTraining the tilt intonation model using the JEMA methodology
This paper focuses on the estimation of the Tilt intonation model [1]. Usually, Tilt events are detected using a first estimation which is improved using gradient descent techniques. To speed up the search we propose to use a closed form expression for some of the Tilt parameters. The gradient descent search is used only for the time related parameters because a close expression cannot be found...
