I have come to the opposite conclusion - YouTube does not reliably include spoken word/transcript matches in search results.

As I wrote in another comment, I've run tests where I open up the transcript of a video using these steps (https://kb.swtc.edu/page.php?id=90230), copy a few of the words, then perform a search using those words across that channel, and the video I copied the words from doesn't appear on the list of results.

If Google decides that it's going to revamp YouTube search to include spoken word/transcription matches, that would make VideoMentions Search irrelevant– and I'd be okay with that!

In the meantime, I think this is a useful free tool for quickly finding spoken word matches within specific channels.

Thanks for checking it out!

I didn't know this...how do you show transcript?

Hey @tomatowurst! You can search within the spoken words/transcript of a single YouTube video by following these steps: https://kb.swtc.edu/page.php?id=90230

This is so cool I had no idea this was possible I would often seek a particular segment manually. Thanks!

Welcome! :)
