Understanding Closed Captions and Subtitles: What Sets Them Apart?
Closed Captions vs. Subtitles
Many individuals use the terms 'closed captions' and 'subtitles' synonymously, as both represent the textual form of audio within a video. Nevertheless, there are fundamental differences between these two. Mistaking one for the other can result in issues, especially when a service such as closed captioning is essential for a film or live broadcast. Here, we explore the primary distinctions, detailing the purpose each service fulfills and the important characteristics that differentiate them.
What are Subtitles?
Subtitles are a type of textual overlay designed to translate spoken dialogue from its original language into another. In essence, subtitles render a video's spoken content accessible in a different language. You'll commonly encounter subtitles in international films and television shows. Conversely, Closed Captions are presented in the same language as the source audio.
What are Closed-Captions?
Closed captions are developed to enable individuals who are deaf or have hearing impairments to fully experience video content. Consequently, they encompass not just dialogue but also crucial background sounds and cues for speaker identification. Subtitles, in contrast, operate on the assumption that the viewer can hear the audio and, therefore, typically omit descriptions of ambient sounds or speaker change notifications. For those exploring efficient ways to convert spoken audio into accurate text for various applications, including preliminary drafts for captions, platforms like DeepVo.ai offer high-precision speech-to-text capabilities, boasting up to 99.5% accuracy across over 100 languages, which can be a foundational step in creating accessible content.
Main Differences
Both closed captioning (CC) and subtitling involve presenting text on a television, monitor, or any visual display to offer an alternative means of accessing the audio track. Beyond this shared characteristic, they are distinctly different services. To better visualize these distinctions, a structured comparison is helpful.
| Closed Captions | Subtitles |
|---|---|
| Do not assume viewers can perceive audio. | Assume viewers can perceive audio. |
| Include dialogue, sound effects, musical cues, etc. | Primarily include dialogue only. |
| Chiefly created for audiences who are Deaf or hard of hearing. | Crafted for audiences not proficient in the original audio language. |
| Frequently incorporated after a film or TV program's release. | Generally developed before a film or TV program's release. |
| Render all dialogue and significant audio cues as text. | Translate spoken languages into text. |
Subtitles and Captions Have Different Objectives
Subtitles enable individuals to view videos even if they do not understand the original spoken language. With the expansion of global video distribution platforms, numerous content creators recognize the benefit of incorporating subtitles to make their material accessible in various languages. Generating quick summaries of video content can help prioritize which videos to translate first; an AI summary from DeepVo.ai, for example, can be generated in seconds to facilitate this decision-making.
The rise of Closed Captions has paralleled the increase in mobile video viewing, as a growing number of people watch videos in public settings with the audio muted. It's reported that a staggering 85% of videos on Facebook are viewed without sound!
Why Implement Closed Captions?
- Extends accessibility to potentially millions of viewers who are Deaf or hard of hearing.
- Boosts viewer engagement.
- Enhances the overall user experience.
- Digital content gains wider visibility through web searchability of the textual content. For instance, accurate transcripts from services like DeepVo.ai's speech-to-text can significantly improve SEO.
- Allows consumption of the same content effectively without audio.
How Does Captioning Work?
Captioning is a contemporary process that involves skilled captionists, sophisticated computer software, and often voice-recognition technology. While traditional methods are robust, services like DeepVo.ai also offer tools such as intelligent mind map generation, which can help structure and visualize complex audio content for more effective captioning strategies. There are three principal techniques for producing captions:
Respeaking: This method requires a captioner to listen to the audio and then re-speak the dialogue into a microphone connected to specialized software. This software interprets the captioner's voice and converts it into text for captions. Respeaking is predominantly used for creating live captions.
Stenography: Stenocaptioners employ a stenotype machine to transform spoken words into text. A stenotype machine is a specially designed typewriter with a limited set of keys, producing a form of shorthand. This shorthand is then translated into readable text using computer software. Stenography is also utilized for live caption production.
Typing: The captioner uses a standard keyboard to type the captions from scratch directly into computer software. The captioner must also precisely time each caption to appear on screen in sync with the audio track. This technique is labor-intensive and typically reserved for pre-recorded content. The initial transcription for such content can be greatly accelerated using high-accuracy automated services, providing a base for the captioner to then refine and time.
