Why We Stand Out

  • We understand your situation. As an agent of change, AST provides user training, personal support, news, and research to address your needs.
  • We understand timelines. AST delivers over 50 closed caption and subtitle formats to you in minutes and high quality transcripts in as little as 8 hours, if you don’t have them.
  • We understand technology growth. AST is known as a leading provider because we are responsive and we’re staying in touch with emerging technology for you.
  • We understand where technology does not measure up. AST uses trained human transcribers to generate high quality transcripts, not speech recognition which produces substandard results.
  • We understand compliance. AST is there, addressing compliance issues, forming partnerships, and setting the bar, for customers around the world so we are there when you need us.

Why Caption? The Unexpected Benefits of Closed Captioning

  • Improved Indexing and Searching: Use closed captions or transcripts as meta data to make your video text-searchable, and to make web-embedded video search engine friendly.
  • Viewer Flexibility: With the increasing popularity of mobile devices, viewers may be in environments where access to the audio is limited. Closed captioning allows them to view content whether they are in the library, at a concert or on a noisy bus.
  • Improved Accessibility for ESL Viewers: There are more viewers with English as a second language than there are with English as a first language — closed captioning helps your message reach larger audiences.
  • Improved Comprehension: Closed captioning improves comprehension and retention of media content for all viewers.
