The Midwest Center for Postsecondary Outreach developed this guide to offer administrators, parents, students, and potential service providers an overview of the various speech-to-text service options available in postsecondary environments to students who are deaf or hard-of-hearing. Speech-to-text services are support options for students who are deaf or hard-of-hearing to use in an educational environment. A speech-to-text service provider listens to a speaker and using an input device produces text on a computer screen for the student to read. The text can also be displayed on a TV monitor or projected on a screen. All services discussed in this guide are provided in real-time (as it is happening) rather than the alternative of transcribing a recorded lecture. It is important to note that speech-to-text services are constantly changing as newer technology is developed and existing technology improves. Speech-to-text services (and providers) vary in accuracy related to content and wording as well as the number of pages/words produced in a transcript. These topics are addressed in each speech-to-text service section included in this guide, however, it is suggested that individuals and/or institutions using these services investigate each method of speech-to-text services (as well as the provider) to determine content and wording accuracy in real-time. While speech-to-text service providers are often referred to as captionists, transcribers, voice writers, and other titles, the term "provider" in this guide refers to the person producing a real-time text display, no matter which input device is being used.
