While the university does not have a specific contract with a captioning company, your department can pay with your Purchasing Card or through EBS system.

These companies are pay-per-use services. There is no special software to buy or install. Users choose the services they need (transcripts, captioning, or both) and are billed on a monthly basis. A department, or individual, may pre-purchase hours of service at a discounted rate if they need a large number of transcripts or caption serviced.

See the MSU Web Accessibility website site for other captioning information.
