Subtitles and Caption Closed vs Open Captions and Technology 1 — Questions and Answers
Question 1: What is the fundamental difference between 'open captions' and 'closed captions'?
- Open captions are permanently visible to all viewers; closed captions can be toggled on or off (Correct answer)
- Open captions are free of charge; closed captions require a subscription
- Open captions appear on top of the screen; closed captions appear at the bottom
- Open captions are in color; closed captions are in black and white
Correct answer: Open captions are permanently visible to all viewers; closed captions can be toggled on or off
Open captions are burned into the video and always visible, while closed captions are encoded separately and can be turned on or off by the viewer.
Question 2: Automatic Speech Recognition (ASR) in captioning refers to:
- Software that converts spoken audio to text automatically using AI (Correct answer)
- A hardware device that decodes caption signals in televisions
- A certification program for human captioners
- A government standard for caption accuracy
Correct answer: Software that converts spoken audio to text automatically using AI
ASR technology uses artificial intelligence to transcribe spoken audio into text automatically, and is increasingly used for both live and recorded captioning.
Question 3: What is the main accuracy limitation of Automatic Speech Recognition (ASR) captioning?
- It struggles with accents, technical jargon, background noise, and multiple overlapping speakers (Correct answer)
- It cannot process audio faster than 100 words per minute
- It only works with English-language content
- It requires an internet connection to function
Correct answer: It struggles with accents, technical jargon, background noise, and multiple overlapping speakers
ASR accuracy decreases significantly with accents, specialized terminology, background noise, and simultaneous speakers.
Question 4: What captioning method uses trained stenographers typing on a phonetic keyboard to produce real-time captions?
- Stenographic CART captioning (Correct answer)
- Respeaking
- Automatic Speech Recognition
- Typewriter captioning
Correct answer: Stenographic CART captioning
Stenographic CART captioning uses professional stenographers on phonetic keyboards to produce real-time captions at high speed and accuracy.
Question 5: What is 'respeaking' as a live captioning method?
- A captioner repeats audio into voice recognition software that generates the caption text (Correct answer)
- A second captioner reviews and corrects another captioner's work in real time
- An automated system re-speaks captions in a different language
- Replaying recorded audio to assist a human transcriber
Correct answer: A captioner repeats audio into voice recognition software that generates the caption text
In respeaking, a trained captioner listens to audio and repeats it clearly into voice recognition software that converts it to caption text.
Question 6: Which subtitle file format stores timing in milliseconds using an arrow notation (-->) to separate in and out times?
- SRT (SubRip Text) (Correct answer)
- WebVTT
- STL
- TTML
Correct answer: SRT (SubRip Text)
SRT files use a simple format with a sequence number, timecode line using --> notation in HH:MM:SS,ms format, and text lines.
