What is Captions Quality and how to ensure it?
Closed Captions are a must-have for deaf and hard to hear people comprehend and enjoy the audio-visual content.
According to DCMP (Described and Captioned Media Program), there are more than 30 million Americans with some type of hearing loss. If extended to the worldwide population, this number will easily grow to a few hundred million. This is a large population that needs effective and high-quality Closed Captions to comprehend the media content.
And it is often stated that Captions should be of “high quality” to be effective for this population.
But how does one define this “high quality” for Captions?
According to DCMP, the following are key elements of Captioning Quality:
- Errorless captions for each production.
- Uniformity in style and presentation of all captioning features.
- A complete textual representation of the audio, including speaker identification and non-speech information.
- Captions are displayed with enough time to be read completely, are in synchronization with the audio, and are not obscured by (nor do they obscure) the visual content.
- Equal access requires that the meaning and intention of the material are completely preserved.
Every caption service provider needs to ensure that they create “quality captions” meeting the above guidelines. And every content provider, whether a Broadcaster or a Streaming service provider, needs to ensure that they deliver high quality captions to their viewers. Failing these captioning quality standards can have a detrimental effect on their brand and people will be less enthused in signing up or continuing with their captioning/subtitling service.
Checking for all these parameters and correcting them can be resource-intensive, tedious, and cost-prohibitive. Nowadays, the same content is delivered through a variety of mediums, which may use different audio-visual content versions due to specific editing, frame rate, and other technical requirements. It is essential that the captions are also properly edited for these different content versions. Due to the sheer content volume and the cost involved in Caption/Subtitle QC & correction of each content version, captioning service providers may choose to not perform full QC on all the caption files, leading to low quality and erroneous captions. It is therefore important to bring automation in the QC process so that QC process itself becomes feasible and more manageable for everyone in the content production and delivery chain.

- Characters per line: Readability issue
- Characters per second: Readability issue
- Words per minute: Readability issue
