In today’s digital landscape, both video and podcast content are more abundant than ever. While this offers a rich array of choices for consumers, it also presents a challenge: how to sift through hours of material to find the most engaging moments. Traditional methods often fall short, but Artificial Intelligence (AI) is stepping in to offer a multi-step, comprehensive approach to curating highlights for both mediums.
The AI-Driven Methodology
Step 1: Transcription with OpenAI’s Whisper
The initial step in this AI-driven process is to transcribe the audio, whether it’s from a video or a podcast. OpenAI’s Whisper is a highly accurate tool for this, converting spoken language into text. However, it’s worth noting that Whisper doesn’t support speaker separation, which is essential for understanding the context. Techniques for separating out different speakers from audio are a complex subject and worthy of a separate blog post.
Step 2: Textual Analysis with ChatGPT
After obtaining the transcript, the next step is to feed it to ChatGPT for analysis. The aim is to identify ‘interesting nuggets’ that could serve as potential highlights. The term ‘interesting’ is, of course, subjective and varies from person to person. Despite this, ChatGPT’s advanced natural language processing capabilities offer a good starting point for pinpointing key moments in the transcript.
Step 3: Segmentation and Visual Elements
The final step involves segmenting the content into bite-sized, shareable pieces. For videos, this involves cutting them based on the time stamps provided by ChatGPT’s textual analysis. If you’re working with audio-only content, like podcasts, adding a visual element becomes crucial to attract viewers. This could be a dynamic waveform, relevant images, or even short video clips that align with the audio highlights. Python offers a wide range of libraries and tools to accomplish both tasks efficiently.
Drawbacks and Limitations
While efficient and comprehensive, this AI-driven method has its limitations. The most significant drawback is the loss of visual context when relying solely on transcripts. Non-verbal cues like facial expressions or dramatic moments that contribute to the emotional weight or humor in a scene are often lost. This is particularly relevant for video content but can also impact the way podcast highlights are curated.
Conclusion
AI offers an exciting, multi-faceted approach to generating highlights for podcasts and videos. By combining the capabilities of Whisper for transcription and ChatGPT for textual analysis, this methodology provides a quicker, more objective, and adaptable way to curate content. Although it has its limitations, such as the loss of visual context, the approach represents a significant advancement in the automation of content curation. As technology continues to evolve, we can expect even more nuanced and context-aware systems that will make our consumption of podcasts and videos more engaging and enjoyable.
