Dalam makalah ini, kaedah baru untuk mengurangkan bunyi bising yang berubah-ubah masa tambahan dicadangkan. Tidak seperti kaedah sebelumnya, kaedah yang dicadangkan tidak memerlukan andaian tentang hingar mahupun anggaran statistik hingar dari mana-mana kawasan jeda. Penambahbaikan dilakukan berdasarkan jalur demi jalur untuk setiap rangka masa. Berdasarkan kedua-dua keputusan sama ada jalur tertentu dalam bingkai adalah pertuturan atau bunyi yang dominan dan sifat penyamaran sistem pendengaran manusia, jumlah hingar yang sesuai dikurangkan dalam domain frekuensi masa menggunakan penolakan spektrum yang diubah suai. Kaedah yang dicadangkan telah diuji pada pelbagai keadaan bising: hingar kereta, hingar F16, hingar Gaussian putih, hingar merah jambu, bunyi tangki dan bunyi celoteh. Berdasarkan SNR segmen, pemeriksaan spektrogram dan ujian MOS, kaedah yang dicadangkan didapati lebih berkesan daripada penolakan spektrum dengan dan tanpa pengesanan jeda dalam mengurangkan hingar sambil meminimumkan herotan kepada pertuturan.

Sukhyun YOON, Chang D. YOO, "Speech Enhancement Based on Speech/Noise-Dominant Decision" in IEICE TRANSACTIONS on Information,
vol. E85-D, no. 4, pp. 744-750, April 2002, doi: .
Abstract: In this paper, a novel method to reduce additive time-varying noise is proposed. Unlike the previous methods, the proposed method requires neither the assumption about noise nor the estimate of the noise statistics from any pause regions. The enhancement is performed on a band-by-band basis for each time frame. Based on both the decision on whether a particular band in a frame is speech or noise dominant and the masking property of the human auditory system, an appropriate amount of noise is reduced in time-frequency domain using modified spectral subtraction. The proposed method was tested on various noisy conditions: car noise, F16 noise, white Gaussian noise, pink noise, tank noise and babble noise. On the basis of segmental SNR, inspection of spectrograms and MOS tests, the proposed method was found to be more effective than spectral subtraction with and without pause detection in reducing noise while minimizing distortion to speech.
