چکیده مقاله :
جهت‌يابي دو يا چند گوينده که به‌طور هم‌زمان صحبت مي‌کنند يکي از موضوعات مورد علاقه مي‌باشد. در اين مقاله الگوريتم TFCS را براي جهت‌يابي چند گوينده پيشنهاد مي‌کنيم. در اين الگوريتم نيازي به اعمال محدوديت بر روي سيگنال‌ها و يا محيط وجود ندارد. نتايج شبيه‌سازي‌ها نشان مي‌دهد که الگوريتم پيشنهادي داراي دقت تخمين جهت بيشتري نسبت به روش‌هاي طيف فرکانسي و onset که اخيراً پيشنهاد شده‌اند، دارد.
Estimation of speakers' directions is one of the interesting topics. In this paper, we introduce the TFCS algorithm for direction-of-arrival estimation of multiple speakers. In this algorithm, no limitations are imposed on the environment and speech signals. Simulation results show that the proposed algorithm outperforms the recently addressed onset and spectral-based methods.
