Enhanced pitch tracking and the processing of F0 contours for computer aided intonation teaching
نویسندگان
چکیده
A comparative evaluation of several pitch determination algorithms (PDAs) is presented. Fundamental frequency estimates, F0, are compared with laryngeal frequency estimates , Lx. An algorithm is presented which enables Lx contours to be generated from laryngograph data. We seek the most accurate method of F0 extraction in order to minimise errors propagating into subsequent prosodic analysis. The super resolution pitch determinator 3] performs well relative to the other PDAs studied. Modiica-tions made to this algorithm are described, which radically reduce the number of gross F0 errors and improve the clas-siication of voiced and unvoiced sections of speech. The raw F0 contours produced by this enhanced algorithm are processed to form schematised contours used in computer aided intonation teaching. The series of processes used in the schematisation is described.

The role of intonation in emotional expressions
The influence of emotions on intonation patterns (more specifically F0/pitch contours) is addressed in this article. A number of authors have claimed that specific intonation patterns reflect specific emotions, whereas others have found little evidence supporting this claim and argued that F0/pitch and other vocal aspects are continuously, rather than categorically, affected by emotions and/or ...
متن کاملIs there an emotion signature in into it be used in syn
Intonation is often considered to play an important role in the vocal communication of emotion. Early studies using pitch manipulation have supported this view. However, the properties of pitch contours involved in marking emotional state remain largely unidentified. In this contribution, a corpus of actor-generated utterances for 8 emotions was used to measure intonation (pitch contour) by ide...
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 کاملIntonation processing for TTS using stylization and neural network learning method
In this paper, we propose a new model for synthesizing fundamental frequency (F0) contours using a stylization and a neural network learning method. The F0 contour is described as the superposition of 4 layered features; global tune, word pitch bias, lexical tone, and the syllabic pitch pattern. We rstly stylize the F0 contour of speech material, and analyze stylized data by statistical approac...
