    　View Summary

    We developed a three-dimensional mechanical vocal cord model for Waseda Talker No. 7 (WT-7), an anthropomorphic talking robot, for generating speech sounds with various voice qualities. The vocal cord model is a cover model that has two thin folds made of thermoplastic material. The model self-oscillates by airflow exhausted from the lung model and generates the glottal sound source, which is fed into the vocal tract for generating the speech sound. Using the vocal cord model, breathy and creaky voices, as well as the modal (normal) voice, were produced in a manner similar to the human laryngeal control. The breathy voice is characterized by a noisy component mixed with the periodic glottal sound source and the creaky voice is characterized by an extremely low-pitch vibration. The breathy voice was produced by adjusting the glottal opening and generating the turbulence noise by the airflow just above the glottis. The creaky voice was produced by adjusting the vocal cord tension, the sub-glottal pressure and the vibration mass so as to generate a double-pitch vibration with a long pitch interval. The vocal cord model used to produce these voice qualities was evaluated in terms of the vibration pattern as measured by a high-speed camera, the glottal airflow and the acoustic characteristics of the glottal sound source, as compared to the data for a human.

    　View Summary

    We propose three methods for implementing an improved MPEG-2/4 Advanced Audio Coding (AAC) encoder. The naive implementation using only the informative part of the AAC standard results in coded audio signals with a significantly poor quality. However, the encoder implementation can be modified to improve coding efficiency. Some coding modules require more sophisticated methods for improving the quality. The first among the three methods is a grouping method in the short block mode of AAC. The second is a codebook selection method in the Huffman coding. The third is the scale-factor sectioning method in bit allocation to the frequency components. We also present the methods proposed in our previous papers. The efficiency of the proposed methods has been evaluated objectively and subjectively. We have confirmed that the proposed methods are capable of improving the quality of encoded streams. © 2008 The Acoustical Society of Japan.

    WT-5 (Waseda Talker No. 5), a new anthropomorphic talking robot have been developed with novel vocal cords based on human biomechanical structure. The mechanical vocal cord model has vocal folds with hollow to reproduce layer structure of human vocal cords. The vocal cords are formed by using the thermoplastic rubber "Septon", available from Kuraray Co. Ltd., which has similar elasticity to human tissue. The vocal cords self-oscillate driven by an air flow exhausted from a mechanical lung in similar manner to a human. With new mechanisms, the robot produces natural sounding voices closer to those of a human.

  • Three-dimensional electromagnetic articulography: A measurement principle

    T Kaburagi, K Wakamiya, M Honda

    JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA   118 ( 1 ) 428 - 443  2005.07  [Refereed]

    　View Summary

    A measurement principle of the three-dimensional electromagnetic articulographic device is presented. The state of the miniature receiver coil is described by five variables representing the position in the three-dimensional coordinate system and the rotation angles relative to it. When the receiver coil is placed in the magnetic field produced from the distributed transmitter coils, its state can be optimally estimated by minimizing the difference between the measured strength of the received signal and the predicted one using the known spatial pattern of the magnetic field. Therefore, the design and calibration of the field function inherently determine the accuracy in estimating the state of the receiver coil. The field function in our method is expressed in the form of a multivariate B spline as a function of position in the three-dimensional space. Because of the piecewise property of the basis function and the freedom in the selection of the rank and the number of basis functions, the spline field function has a superior ability to flexibly and accurately represent the actual magnetic field. Given a set of calibration data, the spline function is designed to form a smooth curved surface interpolating all of these data samples. Then, an iterative procedure is employed to solve the nonlinear estimation problem of the receiver state variables. Because the spline basis function is a polynomial, it is also shown that the calculation of the Jacobian or Hessian required to obtain updated quantities for the state variables can be efficiently performed. Finally, experimental results reveal that the measurement accuracy is about 0.2 mm for a preliminary condition, indicating that the method can achieve the degree of precision required for observing articulatory movements in a three-dimensional space. It is also experimentally shown that the Marquardt method is a better nonlinear programming technique than the Gauss-Newton or Newton-Raphson method for solving the receiver state problem.

    　View Summary

    We present a method that determines articulatory movements from speech acoustics using a Hidden Markov Model (HMM)-based speech production model. The model statistically generates speech spectrum and articulatory parameters from a given phonemic string. It consists of HMMs of articulatory parameters for each phoneme and an articulatory-to-acoustic mapping for each HMM state. For a given speech spectrum, maximum a posteriori estimation of the articulatory parameters of the statistical model is presented. The performance on sentences was evaluated by comparing the estimated articulatory parameters with the observed parameters. The average RMS errors of the estimated articulatory parameters were 1.50 mm from the speech acoustics and the phonemic information in an utterance and 1.73 mm from the speech acoustics only.

    　View Summary

    This paper describes the modeling and analysis of an elastic tongue mechanism of a talking robot WT-2 and the development of an acoustic simulator for the construction of the computational model of human speech production. WT-2 consists of lungs, vocal cords and articulators. It is essential to accurately estimate and analyze the shapes of these organs to develop an acoustic simulator However it was difficult to estimate and analyze the mechanisms, because they were composed of an elastic rubber to make various shapes and to seal the air and sound Therefore, we constructed a modeling method to simulate the shape of the elastic mechanisms. This method is applicable to all the elastic body. We developed an acoustic simulator using this modeling method in the process of constructing the speech production model.

    　View Summary

    Electromagnetic articulograph (EMA) devices are capable of measuring movements of the articulatory organs inside and outside the vocal tract with fine spatial and temporal resolutions, thus providing useful articulatory data for investigating the speech production process. The position of the receiver coil is detected in the EMA device on the basis of a field function representing the spatial pattern of the magnetic field in relation to the relative positions of the transmitter and receiver coils. Therefore, the design and calibration of the field function are quite important and influence the accuracy of position detection. This paper presents a nonparametric method For representing the magnetic field, and also describes a method for determining the receiver position from the strength of the induced signal in the receiver coil. The field pattern in this method is expressed by using a multivariate spline as a function of the position in the device's coordinate system. Because of the piecewise property of the basis functions and the freedom in the,,election of the rank and the number of the basis functions, the spline function has a superior ability to flexibly and accurately represent the field pattern, even when it suffers from fluctuations caused by the interference between the transmitting channels. The position of the receiver coil is determined by minimizing the difference between the measured strength of the received signal and the predicted one from the spline representation of the magnetic field, Experimental results show that the error in estimating, the receiver position is less than 0.1 mm for a 14 X 14-cm measurement area, and this error can be further reduced by using a spline-smoothing technique.

    This paper describes compensatory articulatory behavior in response to an unexpected perturbation of the oral cavity. A mechanical device was used to change dynamically the thickness of an artificial palate
    the thickness of the un-inflated artificial palate was increased or the thickness of the already inflated artificial palate was decreased. The palatal perturbations were introduced under conditions of normal and masked auditory feedback. Acoustic, perceptual, and speech movement changes were examined in response to the experimental conditions. An EMA system was used to look for evidence of compensatory articulation during the utterance of repeated CV syllables containing fricative /∫/ and affricate /t∫/. When perturbation by palatal inflation was randomly given just before the initial syllable in the repeated fricative syllable, there was frequent overshoot of the tongue in forming the constriction, causing speech errors in the first syllable with the fricative. Compensation by the tongue for the unexpected palatal inflation became evident around the second syllable and the speech error disappeared in the successive syllables. Even when auditory feedback was masked, rapid compensatory articulation of the tongue was observed around the second syllable, but speech errors randomly occurred in the successive syllables. This fact suggests that tactile feedback gathered by sensing contact between tongue and inflated artificial palate is primarily used to develop the rapid compensation, and that auditory feedback is used in finely adjusting articulation with a longer time lag. © 2002 Elsevier Science Ltd.

  • Determination of articulatory movements from speech acoustics using an HMM-based speech production model

    S Hiroya, M Honda

    2002 IEEE INTERNATIONAL CONFERENCE ON ACOUSTICS, SPEECH, AND SIGNAL PROCESSING, VOLS I-IV, PROCEEDINGS     437 - 440  2002  [Refereed]

    　View Summary

    We present a method that determines articulatory movements from speech acoustics using an HMM (Hidden Markov Model)-based speech production model. The model statistically generates speech acoustics and articulatory movements from a given phonemic string. It consists of HMMs of articulatory movements for each phoneme and an articulatory-to-acoustic mapping. For a given speech acoustics, maximum likelihood estimation of the articulatory parameters in the statistical model is presented. An experiment was conducted to evaluate the method on sentences, and estimated articulatory parameters were compared with the observed parameters. The rms error of the estimated articulatory parameters is about 2.12 mm on average.

    In this research, we investigate mechanism of pathological voice generation by means of mechanical speech production model. For this purpose, we develop a mechanical vocal cord model mimicking geometrical shape of pathological vocal cords and its laryngeal control structure. By using the model, we reproduce pathological vocal cord vibration for various vocal cord models with different shape and unbalanced laryngeal control. Then, we investigate the relationship between the geometrical and control parameters of the model and the characteristics of the vocal cord vibration and the acoustic consequence.

    The research project was aiming to clarify quantitatively speech production process and its control strategy by using a mechanical speech production model (Talking ROBOT) which is mimicking the human mechanism. We realized to reproduce speech sounds with various voice qualities such as breathy voice and creaky voice as well as laughter and laughing voice by using the laryngeal control of the model which is similar to the human control. We also examined the vocal cord vibration behavior and aero-acoustic phenomenon in generating these voice sounds by the direct measurement.

    　View Summary

    A scheme for communicative prosody generation was proposed to synthesize speech needed for conversational purposes. Using the correlation between communicative prosody and impression attributes of lexicons constituting output, the proposed scheme enables prosody control for conversational speech output. Perceptual experiments showed the superiority of the speech synthesized with the proposed communicative prosody to the conventional one with reading style prosody. Further application to Chinese and English speech synthesis and the reverse technology of impression extraction from speech clarified the usefulness of the proposed approach.

    　View Summary

    In this study, we examined a framework of communication systems that interact with users spontaneously so as to cope with practical dialogue environments. While conventional spoken dialogue systems aimed to efficiently achieve specific speech-dialogue tasks, the framework of spontaneous communication system was developed in order to evolve these spoken dialogue systems to one that spontaneously start and continue spoken dialogues.
    For this purpose, three studies were conducted : (i) understanding of dialogue environment, which aims advanced human recognition and spoken dialogue recognition using image and speech signal, (ii) spontaneous communication management model, which models how to start, continue and end spoken dialogues, and(iii) speech generation and motion expression technology, which is how to present intentions of the system by utterances or motions.
    In the study(i), human pose estimation using stereo camera was developed. Simultaneous adoption of information of space depth of images, and shapes and textures of either human bodies or clothes realized accurate estimation of human poses. In addition, estimation of utterance intention was studied. Using characteristics of end of sentences and word N-grams, more accurate utterance intention was achieved.
    In the study(ii), models for a robot to start communication with a human, to continue it, and to end it were developed. we developed mental-state of a conversational partner for these purposes.
    In the study a speech generation technique for laughter was developed. Based on acoustical analyses of human laughter syntheses of both laughter and laughter-speech were realized. Throughout these three studies, basic framework of spontaneous communication was established.

    　View Summary

    We have been studied speech acquisition mechanism based on sensory information in perturbation studies of sensory feedback during speech articulation and constructive studies by using mechanical talking robot mimicking human speech production.1. Perturbation Study : We investigated sensory feedback effects on speech production by using a perturbation paradigm. The external perturbation was unexpectedly applied on the palatal shape during speech utterance under the masked auditory and tactile feedback conditions. Then, we observed brain activity by using fMRI during the compensatory response by the tongue to the perturbation. We found that the compensatory response was brought by the neural adaptation mechanism in the central nerves system.2. Talking Robot Study : We have developed an 3 dimensional talking robot (mechanical speech synthesizer) which mimicking human speech production process. This robot has artificial mechanical lung, glottis, tongue, jaw, lips and velum as speech organs which are dynamically controlled by servo mechanism. The speech sounds are produced by glottal source generated by self-oscillating vocal cords, random source generated by passing the air flow through the narrow constriction in the vocal tract, and time varying vocal tract acoustic resonance. The talking robot is dynamically controlled by feed-forward-feedback mechanism. The control planning is automatically trained for a desired speech acoustics and sensory information like tactile information between the tongue and the palate and oral pressure. We proposed a stochastic speech inversion method for mapping the speech acoustics to the articulatory positions based on Hidden Markov Model. Also, we proposed a planning method based on a Jacobean updating rule to determine the articulatory positions from the sensory information. The larynx control planning is also studied based on forward-inverse neural network model for determining the robot parameters of larynx for a desired acoustics like pitch frequency, voice-unvoiced information, and voice quality
