  • The Sound Quality Improvement by Removal Phonological for Singing System Based on LPC Residual Wave Reviewed

    Himeno Takashi, Tanaka Yuto, Mizumachi Mitsunori, Matsui Kenji, Nakatoh Yoshihisa

    We propose a singing system to transmit the pseudo-vocal sound source into the vocal tract. In this paper, we examine the pseudo-vocal sound source that is suitable for singing system. So we carried out a comparison of LPC residual wave and Bark-LPC residual wave that the phonological component included in pseudo-vocal sound source was removed by Bark spectrum. As a result, we found that although the singing voice using Bark-LPC residual is in the low natural tendencies, the Bark-LPC residual wave can reproduce a higher speaker information contributed by the speaker characteristics.

    <p><i>This study aimed to evaluate the effectiveness of an exercise on the people with autism spectrum disorder using the NeuCube spiking neural network (SNN) architecture. We collected EEG patterns during perception and imitation of facial expressions for each emotion. Comparing the collected data in perceiving and mimicking facial expressions, EEG patterns of typically developed person were very similar. This fact suggest that it seems that there are mirror neurons on facial expression in the human brain. Recently, some studies have been reported that mirror neuron system does not work well in the case of subjects with brain disorders. In this paper, we observed mirror neurons during normal perception and imitation of facial expressions in typically developed subjects (TP), ASD subjects who exercise regularly (ASDe), and ASD subjects who don't exercise regularly (ASDn). As a result of experiments, we confirmed the mirror neuron activities of ASDe subjects tend to be close to ones of TP subjects compared to ones of ASDn subjects. The results in the experiments imply the effects of regular exercise on autism spectrum disorder.</i><i> </i></p>

    It is hard to listen to an announcement in a noisy environments such as in a train while running. In this paper, to improve speech intelligibility in a noisy environment, we focused on the time variation of speech spectral representing spectral flux from the analysis result which clear speech has larger spectral flux than normal speech. Therefore, we propose speech enhancement method of spectral variation to improve the sound quality evaluation value of STOI. In the evaluation results of STOI score, enhanced speech by proposed method improved more than original speech in all the SNR conditions (SNR = -5, -10, -15 dB). Also, the significant difference in the dangerous rate of 5% was found in SNR = -10, -15 dB.

    Advanced nations including Japan are facing aging societies. Aging decreases the ability in speech communication. In this paper, aging effect on speech is investigated in the viewpoint of static characteristics. Japanese words uttered by 21 elderly speakers, of which ages range from 64 years old to 87 years old, are used for calculating their power spectra. Concerning Japanese five vowels, the power spectra are calculated only using the initial phonemes of the words. The power spectra for elderly speakers decrease in the frequency range between 2.5 kHz and 4.5 kHz, and increase in higher frequency range over 4.5 kHz.

    The linear prediction analysis on a mel- or bark-frequency scale proposed by Strube is expected to be effective in speech recognition as the MFCC or PLP analysis because of their auditory-like frequency resolution. However, this method has been rarely used speech recognition applications due to relatively high computational load compared to the standard LPC analysis. This paper proposes a simple and efficient time-domain technique (Mel-LPC analysis) to estimate warped predictors. This analysis is accomplished with about two-fold increase in computation over the standard LPC analysis. The recognition performance of mel-cepstral parameters obtained by the Mel-LPC analysis is compared with that of the conventional LPC mel-cepstra through speaker independent phoneme recognition. The results show that the Mel-LPC cepstrum leads to the improvement from 64.8% for the standard LPC mel-cepstrum to 73.4% in phoneme recognition accuracy, and the improvement from 92.7% for the standard LPC mel-cepstrum to 96.0% in word recognition accuracy (520 vocabulary word).

    We have developed a speech sensor system for video conference that eliminates the need for manual camera switching.To avoid being influenced by extraneous noises,the system distinguishes speech from noises by a fuzzy-logic technique that recognizes typical Japanese speech characteristics,and attains a noise rejection rate of 98.3%.Also the system calculates a cross- correlation function between two microphones to identify the spatial location of the person speaking.
