Resynthesis the correct tone utterance of a sentence from a corresponding arbitrary tone utterance
ثبت نشده
چکیده
The current paper presents a system that generates tones automatically from utterances and sentences. Users were asked to speak a sentence displayed on the screen with any arbitrary tone sequence (level and falling tones is preferred). The system records the utterance, determines the correct tone sequence from the sentence, determiners syllable boundaries by force-aligning the utterance, generates a new Northern Vietnamese tone F0 contour by Fujisaki model, then resynthesize the utterance with the new tone sequence. The system could be applied in teaching foreigners to speak Vietnamese with the correct tones or converting utterances of a Middle Vietnam or Southern Vietnam speaker to Northern tone system.

Quantitative analysis of intonation patterns in statements and questions in Cantonese
The aim of this study was to investigate intonation patterns in Cantonese using a quantitative approach. The commandresponse model was employed to explore the differences between intonations, and the effects of lexical tone on fundamental frequency (F0) contours of intonation. Two intonation types (statements and questions), with six tonal contrasts embedded at the final position of the utteran...
متن کاملTone, Utterance Length and F0 Scaling
One important strand of research into the scaling of fundamental frequency has been concerned with the hypothesis that utterance length is a determining factor of initial pitch height, with longer utterances involving a higher initial F0 than that found in shorter utterances. Most work in this vein has been done on ‘intonation’ languages, with very little investigation having been carried out o...
متن کاملEmotional Expressiveness of Successive Addition Boundary Tone in Mandarin Chinese
The aim of the present study is to explore the relationship between the form of Chinese ‘successive addition boundary tone’ [1,2] and its expressive function, and whether ‘SUccessive Addition Boundary Tones’ (SUABT) can uniquely encode pragmatic information. To this end, a perceptual experiment was conducted by attaching a successive falling tone to the F0 curve of the neutrally expressed utter...
متن کاملThe relationship between utterance type and F0 contour in German
In this study we investigate the intonational characteristics of the four utterance types statement, wh-question, yes/no-question and declarative question. Readings of two German scripted dialogues were examined to ascertain characteristic features of the F0 contour for each utterance type. Final boundary tone, nuclear pitch accent, F0 offset, F0 onset, F0 range, and the slopes of a topline and...
متن کاملImproved Prediction of Tone Components for F0 Contour Generation of Mandarin Speech Based on the Tone Nucleus Model
Improved prediction of tone components was realized in our method for synthesizing sentence fundamental frequency (F0) contours of Mandarin speech. The method is based on representing a sentence logarithmic F0 contour as a superposition of tone components on phrase components as in the case of generation process model (F0 model). The tone components are realized by concatenating their fragments...
