Automated AI Closed Captioning and Subtitling Workflow Guide

Automated Closed Captioning and Subtitling Workflow

1. Content Preparation

1.1 Video Upload

Educators upload video content to an AI-enabled platform such as Veed.io or Kapwing.

1.2 Video Analysis

The platform analyzes the video for audio quality and speech clarity using AI algorithms to determine the best captioning approach.

2. Speech Recognition

2.1 Audio Transcription

AI-driven tools like Google Cloud Speech-to-Text or IBM Watson Speech to Text transcribe spoken dialogue into text format.

2.2 Accuracy Enhancement

Implement machine learning models that refine transcription accuracy by learning from user corrections and feedback.

3. Caption Generation

3.1 Automatic Caption Creation

Utilize AI tools such as Rev.ai or Subtitle Edit to automatically generate closed captions from the transcribed text.

3.2 Formatting and Timing

AI algorithms adjust the timing and formatting of captions to ensure they sync accurately with the video playback.

4. Review and Editing

4.1 Quality Assurance

Incorporate a review step where educators or designated personnel review the generated captions for accuracy and context.

4.2 Manual Adjustments

Use editing tools within platforms like Amara or Descript for any necessary manual adjustments to captions.

5. Export and Integration

5.1 Export Options

Export the finalized captions in various formats (e.g., SRT, VTT) for compatibility with different video platforms.

5.2 Integration with Learning Management Systems (LMS)

Integrate the captioned videos into LMS platforms such as Moodle or Canvas for seamless access by learners.

6. Feedback and Iteration

6.1 User Feedback Collection

Gather feedback from students regarding the effectiveness and clarity of the captions for continuous improvement.

6.2 AI Model Retraining

Utilize collected feedback to retrain AI models, enhancing future captioning accuracy and user satisfaction.

7. Compliance and Accessibility

7.1 Regulatory Compliance

Ensure all captioning adheres to accessibility standards such as the WCAG guidelines and local regulations.

7.2 Continuous Monitoring

Regularly monitor captioning processes to maintain compliance and adapt to new accessibility requirements.
