Web Watch knows that automatic transcription of speech-to-text for closed captioning still has a ways to go.
A lot has to do with the quality of the source audio material. And if you have poor source audio, the chances are pretty good that the transcribed closed captioning will be off more than just a little bit.
So why not check out this 1950’s educational film, where a young girl asks her mother and sister about getting one’s first period. As it is an old film, you can tell that the audio sounds now as it probably did in the school room back then.
Now click through to YouTube and turn on Closed Captioning, and watch it again.
