Kami mencadangkan kaedah peningkatan pertuturan baharu yang sesuai untuk peranti mudah alih yang digunakan dengan kehadiran pelbagai jenis hingar. Untuk mencapai pengecaman pertuturan berprestasi tinggi dan persepsi pendengaran dalam peranti mudah alih, pelbagai jenis hingar perlu dialih keluar di bawah kekangan susunan mikrofon penjimatan ruang dan sedikit sumber pengiraan. Kaedah yang dicadangkan boleh mengurangkan kedua-dua hingar arah dan hingar meresap di bawah kekangan yang dinyatakan di atas untuk peranti mudah alih dengan menggunakan tatasusunan mikrofon segi empat sama dan menjalankan pemprosesan kos pengiraan rendah yang terdiri daripada pelbagai bentuk pancaran nol, pemilihan saluran kuasa minimum dan penapisan Wiener. Keberkesanan kaedah yang dicadangkan disahkan secara eksperimen dari segi ketepatan pengecaman pertuturan dan kualiti pertuturan apabila kedua-dua hingar arah dan hingar meresap diperhatikan secara serentak; kaedah ini mengurangkan bilangan ralat perkataan dan menambah baik jarak spektrum log berbanding kaedah konvensional.

Abstract: We propose a new speech enhancement method suitable for mobile devices used in the presence of various types of noise. In order to achieve high-performance speech recognition and auditory perception in mobile devices, various types of noise have to be removed under the constraints of a space-saving microphone arrangement and few computational resources. The proposed method can reduce both the directional noise and the diffuse noise under the abovementioned constraints for mobile devices by employing a square microphone array and conducting low-computational-cost processing that consists of multiple null beamforming, minimum power channel selection, and Wiener filtering. The effectiveness of the proposed method is experimentally verified in terms of speech recognition accuracy and speech quality when both the directional noise and the diffuse noise are observed simultaneously; this method reduces the number of word errors and improves the log-spectral distances as compared to conventional methods.
