Articulatory Speech Synthesizer

چکیده
The aim of this research was to develop a flexible, high quality articulatory speech synthesis tool. One feature of this research tool is the simulated annealing optimization procedure that is used to optimize the vocal tract parameters to match a specified set of formant characteristics. Another aspect of this study is the derivation of a new form of the acoustic equations. A transmission-line circuit model of the vocal system, which includes the vocal tract, the nasal tract with sinus cavities, the glottal impedance, the subglottal tract, the excitation source, and the turbulence noise source, was constructed. The acoustic equations of the vocal system were rederived for the proposed articulatory synthesizer. A digital time-domain approach was used to simulate the dynamic properties of the vocal system as well as to improve the quality of the synthesized speech.

Control of an articulatory speech synthesizer based on dynamic approximation of spatial articulatory targets
We present a novel approach to the generation of speech movements for an articulatory speech synthesizer. The movements of the articulators are modeled by dynamical third order linear systems that respond to sequences of simple motor commands. The motor commands are derived automatically from a high level schedule for the input phonemes. The proposed model considers velocity differences of the ...
متن کاملA Gesture-Based Concept for Speech Movement Control in Articulatory Speech Synthesis
An articulatory speech synthesizer comprising a three-dimensional vocal tract model and a gesture-based concept for control of articulatory movements is introduced and discussed in this paper. A modular learning concept based on speech perception is outlined for the creation of gestural control rules. The learning concept includes on sensory feedback information for articulatory states produced...
متن کاملKnowledge from Speech Production Used in Speech Technology: Articulatory Synthesis*
There appears to be a continuing trend toward incorporating knowledge of speech production into s~eech technology-text-to-speech synthesis (e.g., BIckley, Stevens, & Williams, 1994; Parthasarthy & Coker, 1992), low bit rate coding (see Schroeter & Sondhi, 1992), and automatic speech recognition (e.g., Rose, Schroeter, & Sondhi, 1994; Shirai & Kobayashi, 1986). For automatic speech recognition, ...
متن کاملImitating Conversational Laughter with an Articulatory Speech Synthesizer
In this study we present initial efforts to model laughter with an articulatory speech synthesizer. We aimed at imitating a real laugh taken from a spontaneous speech database and created several synthetic versions of it using articulatory synthesis and diphone synthesis. In modeling laughter with articulatory synthesis, we also approximated features like breathing noises that do not normally o...

We describe our research direction to build a 3-D articulatory speech synthesizer. We are employing a usercentred design approach to develop the synthesizer. The end result will be added to the open-source research community. The system infrastructure we are planning is expected to allow for easy integration of current and future research results in vocal tract modelling and vocal sound product...
متن کاملReal-Time Control of an Articulatory-Based Speech Synthesizer for Brain Computer Interfaces
Restoring natural speech in paralyzed and aphasic people could be achieved using a Brain-Computer Interface (BCI) controlling a speech synthesizer in real-time. To reach this goal, a prerequisite is to develop a speech synthesizer producing intelligible speech in real-time with a reasonable number of control parameters. We present here an articulatory-based speech synthesizer that can be contro...
