چکیده

We propose a way of synthesizing Thai vowels, monophthong and diphthong which consist of nine short-long vowel pairs and three short-long vowel pairs respectively. By adjusting the fundamental frequency or pitch contour, the five tonal of these vowels can be synthesized, leading to a total of 120 phonemes. We evaluate the synthesized monophthongs by comparing the first and second formants to standard in terms of different percentages, which result in 9.89% and 7.44% respectively. For the synthesis of diphthongs, we slide from one vocal-tract vowel to another using linear, logarithmic, or exponential functions.

Identifying underlying articulatory targets of Thai vowels from acoustic data based on an analysis-by-synthesis approach

This paper investigates the estimation of underlying articulatory targets of Thai vowels as invariant representation of vocal tract shapes by means of analysis-by-synthesis based on acoustic data. The basic idea is to simulate the process of learning speech production as a distal learning task, with acoustic signals of natural utterances in the form of Mel-frequency cepstral coefficients (MFCCs...

The Articulatory TBU: Gestural Coordination of Lexical Tone in Thai

Recent literature in Articulatory Phonology (AP) has promoted the idea that tone is an articulatory gesture, similar to those that make up consonants and vowels (Prieto and Torreira 2007, Gao 2008). When treated as gestures, tones should be co-selected and coordinated like other articulatory gestures. The co-selection of T(one) gestures with C(onsonant) and V(owel) gestures is reminiscent of th...

Analysis and modeling of syllable duration for Thai speech synthesis

This paper describes the analysis results on the control factors of Thai syllable duration, and a statistical control model using linear regression technique. The analyses have been carried out both at a syllable level and at a phrase level. In a syllable level duration control, the effects of five Thai tones and syllable structures are investigated. To analyze syllable structure effects statis...

Synthesis of Thai Monophthongs by Articulatory Modeling

The objective of this paper is to propose a synthesis of some Thai monophthongs by basic articulatory synthesis. In this paper we first describe human speech production mechanism. After that we mention articulatory synthesis method. Our basic idea is to model the human articulators and vocal cords. The articulators are usually modeled with a set of area functions between glottis and mouth in or...

Modeling Consonant-Vowel Coarticulation for Articulatory Speech Synthesis

A central challenge for articulatory speech synthesis is the simulation of realistic articulatory movements, which is critical for the generation of highly natural and intelligible speech. This includes modeling coarticulation, i.e., the context-dependent variation of the articulatory and acoustic realization of phonemes, especially of consonants. Here we propose a method to simulate the contex...
