What Are Emotion Subtitles?

Emotion subtitles are a new way to get Factba.se's unique analysis inline with your video experience. In short, you can see what a person is feeling and get a measure of their comfort with a topic right in the video.

Factba.se analyzes not just the text, but the audio and video with a particular speech or interview. Part of that analysis measures the level of stress in a person's voice, along with intonation and inflection. This allows us to quantify, mathematically, both the emotions being expressed subconsciously, along with the level of comfort with a particular topic.

Can This Detect Lies?

No. This is hotly debated, and we prefer to stick with the known. It has not been proven definitively that increases in voice stress indicate lies. If a person believes a lie, they will be relaxed. If a person steps on a tack, stress will increase even if telling the truth.

What this does definitely detect is a level of comfort. The higher the frequency (due to muscles contracting, including muscles in the neck that affect the voice box, thus the frequency), the greater the indication of stress. By measuring patterns in when this occurs, we can identify statements and topics where a person is not comfortable with what they are saying. Coupled with identification the underlying feelings and measuring factors such as word choice and rate of speech, among several dozen others (we gather 115 datapoints per word), it's a powerful way to uncover how someone feels about what they are saying.

Klingon? Seriously?

Seriously. We won't deny the nerdiness. However, there's a good reason for this.

Klingon is one of four languages we identified in YouTube's menu:

  • Klingon
  • Interlingua
  • Interlingue (Occidental)
  • Volapük
...which are constructued -- or artificial -- languages. We confirmed that while some people speak each language, there are zero native-born speakers of these languages anywhere in the world (Esperanto is not on the list for that reason... there are native-born Esperanto speakers).

Since captions are perfect for showing data exactly timed to a video, it was a logical path to follow. However, since they are intended for language-specific translations (or subtitles), there's no "Other" category. So we found languages that would not inconvenience a single person worldwide (with our apologies to the Klingon Language Institute -- vuv loDnI'!... when you raise your children from birth to speak Klingon, well, get help, but we'll also move to another language slot then)

So, in addition to ensuring we upload all our human-edited transcripts in English (the English - Transcription) captions to improve the auto-generated closed captions, we also make sure we're not potentially blocking a language primarily spoken by anyone, anywhere.
