This paper aims to describe the development of computer-based teaching materials to increase phonemic awareness of deaf students in special deaf schools. The development of teaching materials is based on the background of the lack of teaching materials in the learning of Communication Development and Sound and Cadence Performance (PKPBI). This situation resulted in learning becoming less flexible, and not giving many opportunities for students to carry out adequate exploration and learning experiences especially in language development. The main problem of children with hearing impairments is a communication problem rooted in the limitations of language acquisition. The development of language skills in special deaf schools is carried out through language learning, speech training and the development of communication and sound perception and rhythm. The low level of language skills in deaf students in both oral and written schools is one indication that the learning that has been carried out is not optimal. This condition reflects the need for efforts to deepen learning. implying the need for learning as a system is a complex process involving the teacher component, teaching material, strategy and environment.
