Information on the Audio Book Program and access to state-adopted books to help support students with disabilities.

What is the Audio Book Program?

The Clearinghouse for Specialized Media & Technology (CSMT) Production Unit oversees the Audio Production Program which uses advanced technology and to produce high-quality audio recordings of state-adopted textbooks and library books for students in kindergarten through grade eight. Audio format is available to any and all students with a disability that may benefit from this service, not simply those who are blind or have low vision. This resource helps students overcome challenges, develop independence, and connect with literature and interact meaningfully with others about that literature.

About Human and Text-To-Speech Audio Recordings

Audio recordings are produced in human voice or Text-To-Speech wave files. These are then converted to MPEG-2 Audio Layer III (MP3) files for educators to download. Recordists work with audio editors to record the content and graphics in the book. During the Text-To-Speech production, staff convert the electronic text files into a speech synthetic voice. The production team listens to the voice and will phonetically spell words or phrases to humanize the artificial pronunciation, inflection, and reading pace. Furthermore, sound quality specialists edit the human and speech synthetic voice wave files to improve audio, adjust reading speed, and remove extraneous noises, thus providing a better-quality sound recording.
