A binary mask estimated by a two-class support vector machine （SVM） classifier is used to synthesize the enhanced whisper. A novel noise robust feature called Gammatone feature cosine coefficients （GFCCs） extracted by an auditory periphery model is derived and used for the binary mask estimation. The intelligibility performance of the proposed method is evaluated and compared with the traditional speech enhancement methods. Objective and subjective evaluation results indicate that the proposed method can effectively improve the intelligibility of whispered speech which is contaminated by noise. Compared with the power subtract algorithm and the log-MMSE algorithm, both of which do not improve the intelligibility in lower signal-to-noise ratio （SNR） environments, the proposed method has good performance in improving the intelligibility of noisy whisper. Additionally, the intelligibility of the enhanced whispered speech using the proposed method also outperforms that of the corresponding unprocessed noisy whispered speech.展开更多

Specifically, both the spectrum density and different regions of the enhanced spectrum are analyzed. Experimental results show that for a spectrum of some density, the joint time-frequency gain-modification based speech enhancement algorithm achieves significant improvement in intelligibility. Additionally, the spectrum region where the estimated spectrum is smaller than the clean spectrum, is the most important region contributing to intelligibility improvement for the enhanced whisper. The spectrum region where the estimated spectrum is larger than twice the size of the clean spectrum is detrimental to speech intelligibility perception within the whisper context.展开更多

The effectiveness of valence and arousal features in whispered speech emotion classification is studied.Finally,the Gaussian mixture model is studied and applied to whispered speech emotion recognition. The cognitive performance is also considered in emotion recognition so that the recognition errors of whispered speech emotion can be corrected.Based on the cognitive scores,the emotion recognition results can be improved.The results show that the formant features are not significantly related to arousal dimension,while the short-term energy features are related to the emotion changes in arousal dimension.Using the cognitive scores,the recognition results can be improved.展开更多

METHODS： Patients undergoing elective colonoscopy between October 2005 and February 2006 were randomized into either listening to music （Group 1, n = 30） or not listening to music （Group 2, n = 30）. Anxiolytic and analgesic drugs （intravenous midazolam and meperidine） were given according to the patients＇ demand. Administered medications were monitored. We determined their levels of anxiety using the State-Trait Anxiety Inventory Test form. Patients＇ satisfaction, pain, and willingness to undergo a repeated procedure were self-assessed using a visual analog scale. RESULTS： The mean dose of sedative and analgesic drugs used in group 1 （midazolam： 2.1 ± 1.4, meperidine： 18.1 ± 11.7） was smaller than group 2 （midazolam： 2.4 ± 1.0, meperidine： 20.6 ± 11.5）, but without a significant difference （P 〉 0.05）. The mean anxiety level in group 1 was lower than group 2 （36.7 ± 2.2 vs 251.0 ± 1.9, P 〈 0.001）. The mean satisfaction score was higher in group 1 compared to group 2 （87.8 ± 3.1 vs 58.1 ± 3.4, P 〈 0.001）. The mean pain score in group i was lower than group 2 （74.1 ± 4.7 vs 39.0 ± 3.9, P 〈 0.001）. CONCLUSION： Listening to music during colonoscopy helps reduce the dose of sedative medications, as well as patients＇ anxiety, pain, dissatisfaction during the procedure. Therefore, we believe that listening to music can play an adjunctive role to sedation in colonoscopy. It is a simple, inexpensive way to improve patients＇ comfort during the procedure.展开更多

Analysis shows that the effect of the subglottal system is to introduce additional pole-zero pairs into the vocal tract transfer function. Theoretically, the method based on an ARMA process is superior to that based on an AR process in the spectral analysis of the whispered speech. Two methods, the least squared modified Yule-Walker likelihood estimate （LSMY） algorithm and the Frequency-Domain Steiglitz-Mcbide （FDSM） algorithm, are applied to the ARMA mfldel for the whispered speech. The performance evaluation shows that the ARMA model is much more appropriate for representing the whispered speech than the AR model, and the FDSM algorithm provides a name acorate estimation of the whispered speech spectral envelope than the LSMY algorithm with higher conputational complexity.展开更多

In this context, literature is an important source of music culture that takes inspiration from the customs and traditions of a society. Prosodic meter is echoed in form, usul and general structure in works composed from the divan literature and almost lives in the work. In the same way, when examples of folk literature composed by composers and performed by poets and a^lks are examined, it is observed that there are parallels between literary features and form, structure and rhythmic features.

His compositions were played in various countries like Turkey, France （1980-1983）, Canada, Australia, Sweden, Norway, Hungary, Albania, Belgium, Holland, and German, and he also joined lots of seminars, radio, and television programs. His inspirational sources are traditional Turkish music, modern French music, American cultural traditions, as well as jazz, acoustic, and electronic music. His music, in summary, is about taking a little from tonality, twelve-note system, coincidences, improvisations, etc., and joining them with his own experiences like emotions, knowledge, and intelligence. Sakpmar always defends that the composer of the day has to benefit from lots of various sources. He is doing this as well as trying new forms in every new piece. It does not matter if these are tonal, atonal, serial, or modal but it must be personal. All the borders and capacities of the instruments have to be forced.展开更多
