Electronic　artificial　larynx　(EAL)　is　important　speech　rehabilitation　prosthesis　for　laryngectomees.　However,　existing　EAL　have　some　drawbacks　such　as　harsh,　raucous　and　unpleasant　sound.　One　of　the　major　problems　is　radiation-noise.　It　is　a　major　source　of　the　degradation　in　acceptability　and　intelligibility　of　EAL　speech.　In　this　study,　we　restrained　radiated　noise　using　independent　component　analysis　based　adaptive　noise　canceling.　An　acoustic　analysis　of　the　denoised　EAL　speech　revealed　a　significant　reduction　in　the　amount　of　background　noise　yet　preserved　the　acoustic　characteristics　of　the　vocal　output.　Perceptual　evaluation　also　indicated　an　obvious　preference　for　denoised　speech.
