Recently metal roofs were widely utilized in rainwater harvesting, and noise produced by rain on metal roofs cannot be ignored. The goal of this article is to demonstrate the effects of rain noise from the metal roofs on speech identification. Two recordings of rain noise from metal roofs and a speech corpus simulated two actual acoustical listening environments. Two experiments were carried out to investigate the interference of rain noise on speech identification in two different acoustical listening environments. Two different simplified ordinary classroom model were carried out in the article. The experiment 1 was in a classroom with a metal roof and experiment 2 was in two point in a simplified ordinary classroom which is close to other building with metal roofs. Some results were shown speech identification all dropped significantly with SNR reduces.
