It’s rare that a content owner will want content that has multiple languages represented in the same closed captions.ĭiarization deals with the capability of being able to separate different speakers. That said, the use cases for this can be minor. In those scenarios it’s very beneficial for the technology to be able to detect and identify the different languages at any given time, realizing that the language has changed and using a list of words associated with that language. For example, a news program might shift from an announcer in English to an interview with someone speaking in Spanish. While content will generally be in a single language, some content can be be mixed. It has to decipher between actual language and noises. Consequently, it’s important for the AI to be able to know that not every sound is necessarily a word. This can be something like a crowd cheering, but can also be noises like a ball being hit or a player grunting as they trip. For example, if the term “webinar” isn’t known it might give a result like “weapons are” as the closest proximity.Īnother aspect involves being able to recognize and separate sounds from actual speech. If it’s not familiar with a term, it will try its best to link it to something in its vocabulary. Now AI can only transcribe words that it knows.
More advanced AI can handle natural speech, accents and dialects, although accuracy will not be as high as simple speech spoken very clearly.Īrtificial intelligence, as part of the speech recognition process, will try to match what it recognizes as speech against a vocabulary list of terms. Rudimentary offerings require that words be spoken very clearly to be recognized. From this, the AI can begin to work through the audio to match speech to a machine readable format, i.e. The first steps of the process of ASR is being able to receive audio. Many of these are focused around providing not just captions, but to improve accuracy of the final product as well. There are a variety of elements that go into this process, including ASR (Automated Speech Recognition). In overly simplified terms, the way AI creates closed captions is through speech to text. How speech recognition and auto closed captioning works Through utilizing and training AI based solutions, organizations can greatly reduce the time devoted to captioning, speed up the time it takes to get assets ready to be shared with captions and manage larger volumes of content. This is where artificial intelligence and closed captioning is key. For organizations producing a lot of content that also want to keep up with increasing regulations that mandate the inclusion of captions, such as the Americans with Disabilities Act and rules from the FCC, this presents a challenge.

So an hour long video could take anywhere from 5-10 hours to transcribe, essentially taking a full day of work to achieve. For those experienced doing it, the process can take roughly 5-10 times the length of the content. Without some sort of automation, closed captioning is a very time consuming process.
