Abstract

In this paper we will introduce the work of creation of a speech database to develop speech technology for disabled persons, which has been done as part of a national program to help better life for Korean people. We will report about the creation of speech database of a total of 160 persons: prompting items, designs, etc. for the creation of a database which is needed to develop an embedded key-word spotting speech recognition system tailored for the persons disabled in articulation. The created database is being used by the technology development team in the national program to study the phonetic characteristics of the different types of disabled persons, develop the automatic method to assess degrees of disability, investigate the phonetic features of speech of the disabled, and design and implement the software prototype for personal embedded speech recognition systems adapted to the disabled persons.
