Speech Planning of an Anthropomorphic Talking Robot for Consonant Sounds Production

چکیده
This paper describes the speech planning of the anthropomorphic talking robot WT-1R (Waseda Talker-No.1 Refined) for the production of consonant sounds. WT-1R has articulators (the tongue, lips, teeth, nasal cavity and soft palate) and vocal organs (the lungs and vocal cords), and can reproduce human vocal movement. Its total DOF (degrees of freedom) is 15. The vocal movement of WT-1R for vowels is steady. We produced Japanese vowels (/a/, /i/, /u/, /e/, /o/) using the first robot WT-1 in 2000. However, the vocal movement for consonant sounds is transient. We must control the 15-DOF talking robot coordinately in the space and time to reproduce the complicated phenomena of the consonant sounds. Therefore, because the Japanese voice generally consists of two phonemes of the first consonant sound and the last vowel, we proposed the speech planning of WT-1R by considering the phenomenon of the voice as three parts (steady consonant sound, transient consonant sound and vowel). WT-1R could produce Japanese vowels (/a/, /i/, /u/, /e/, /o/) and some consonant sounds (/s/, /h/, /m/, /p/ and /waseda/).

Mechanical Design of a Talking Robot for Natural Vowels and Consonant Sounds
Vocal movement isn't only a movement of the vocal organs. It is also a movement that produces acoustic signals received by hearing as linguistic information through hydroacoustic phenomena along with the formation of the vocal way. The purpose of this research is to make clear the human vocal mechanism from the view of engineering by simulating the vocal movement with a robot, and to create the...

The authors are developing a vocalization training system for the auditory-impaired. The training system employs a talking robot which has mechanical organs like a human. With an adaptive learning strategy using an auditory feedback control, the robot autonomously learns the vocalization to speak like a human, and then reproduces the speech articulation from inputted vocal sounds. In the previo...

The ultimate goal of our study is to create a new speech production system, in which an anthropomorphic hardware talking robot is handled so as to imitate human articulatory movement. We have developed a software motion simulator, which generates control parameter sequences for the talking robot Waseda Talker No. 2 (WT-2) using the trajectories of human articulatory organs during continuous utt...

We have developed a biomechanical vocal cord model for an anthropomorphic talking robot—the Waseda Talker Series. The model mimics the biomechanical structure of human vocal cords and is made of a soft rubber called Septon. It is able to reproduce vocal cord vibrations of the normal (modal) voice in a form similar to the human. We also developed a neural network based model for controlling the ...

A nterior teeth are used directly to articulate some speech sounds, such as the consonants /f/ and /v/, and indirectly to produce other speech sounds, such as the consonant /s/. Thus, it is not surprising to find that prostheses or devices placed near teeth, or replacing teeth, alter speech production. In general the literature dealing with speech changes following dental treatment focuses on a...
