With Ensemble Video, you can add easily add an Audio Description to your videos. You can upload an MP3 or M4A formatted audio file, or you can use the Ensemble Video speech-to-text audio description generator.
What is an Audio Description?
Audio Description involves the accessibility of the visual images of video or other visual mediums for people who are blind, have low vision, or who are otherwise visually impaired. Audio Descriptions attempt to describe what the sighted person takes for granted -- those images that a person who is blind or visually impaired formerly could only experience through the whispered asides from a sighted companion.
Go to the Manage Content form of the Add/Edit wizard and click on the Audio Descriptions tab.
The default mode for audio descriptions is the text-to-speech audio description generator. If you already have an audio description file in MP3 or M4A format, click on the Upload Audio Description Tab.
At the top of the form, you will see a link to any previously uploaded or generated audio description files. You can delete a file, download it, and you can also click Preview to view the video with the audio description.
Generate Audio Descriptions
In the Generate Audio Description interface, you will see a video player, a dropdown to select the “voice” that you want to use for speech-to-text synthesized audio descriptions, and a space to enter the text that will be converted to audio at specific time points in the video. You can play the video and click or type in the text area and the video will automatically stop. Just enter the text you want for audio description and hit Enter and the time point and text will be saved in a list below.
Continue through the video entering as many text audio descriptions as needed.
Edit Audio Description
If you want to edit an existing audio description, just click on the description and you will be able to alter the text or the start time of the audio description.
When you are ready to generate an audio description file, just click the Generate button at the bottom. You will see a message that is shown while the audio description file is being processed.
Once the file is ready, you will see it listed in the audio description file list at the top of the form, and you can click Preview to view your video with the audio descriptions.
Upload Audio Descriptions
Click on the Audio Descriptions tab and then click Upload a File to navigate to the folder and upload an MP3 or M4A audio description file. Alternatively, simply drag-and-drop your audio description file onto the uploader interface widget.
Once you upload, the file will be processed, and you will see a message asking you to wait for processing.
When the file is ready, you will see a message indicating that the file was successfully processed.
When the uploaded file is ready, you will see it listed in the Audio Description file list at the top of the form, and you can click Preview to view your video with the audio descriptions.
