Creating synchronized video captions can be a time-consuming and tedious process. Thankfully, there are a variety of free to low-cost tools that speed up this process. In this session, we will demonstrate how to use speech recognition tools to produce a "raw" transcript and how to synchronize the transcript with a video. Finally we demonstrate the usefulness of Amara, which is a free, web-based portal you can use when you don't own the copyright to a video.
Compare the accuracy of a few speech recognition tools, such as Dragon Naturally Speaking (with and without extensive testing), YouTube's Google API, and IBM Watson's Speech to Text Service, when creating a transcript of an audio or video file.
Tips and tricks for segmenting a "raw" transcript and how to download the auto-captions from YouTube.
- Learn how to use the Aeneas Web App to automatically synchronize the audio from an audio or video file with a transcript. Identify accessibility features of operating systems that can be used to evaluate functional access by users with disabilities.
- Evaluate the accuracy of your closed captioning files (e.g., SRT, VTT, SBV).
Use Amara.org to share a captioned verson of a YouTube video you don't own.
