The global market for Captioning and Subtitling Solutions, now enhanced with AI Real-Time Captions, is predicted to grow substantially, reaching an estimated USD 476.9 million by 2028, increasing from USD 282 million in 2022. This growth, at a rate of 7.7% during the forecast period, is significantly influenced by Artificial Intelligence (AI).

Before we go further, let’s clarify what AI is. In simple terms, AI refers to machines designed to think and act like humans. It’s a simulation of human intelligence in computers and robots.

One of AI’s most significant advancements is in live and real-time captioning. AI real-time captions provide subtitles for live events and streaming videos. Whether it’s a live webinar, a virtual conference, or a live stream, AI-based captioning solutions instantly transcribe spoken words and display them alongside the video.

This instant capability is a major advantage for those with hearing impairments, as it creates an inclusive experience for all viewers. AI real-time captions are also particularly useful in noisy environments, for non-native language speakers, and those who prefer to read while watching videos.

In this blog, we’ll discuss the importance of live and instant transcription, how AI technology improves accuracy, and consider their increasing relevance. We’ll examine the phenomenon of AI real-time captions and its significant impact on accessibility and content engagement.

What Exactly Is AI Real-Time Captions?

What Exactly Is AI Real-Time Captions?

Real-time subtitles, often referred to as Computer-Aided Real-Time Translation (CART), live event captioning, or speech-to-text, are a technology that provides captions for spoken language as it happens. This technology involves converting spoken words into text and displaying them on a screen in real-time.

Real-time captions have become possible due to advancements in AI technology. With over 69% of consumers watching videos without sound, there’s a growing demand to extend closed and live captioning capabilities to content.

The technology behind instant transcription has evolved considerably in recent years. Initially, a human captioner would manually type spoken language into a stenography machine. Today, various software solutions make use of Automatic Speech Recognition (ASR) technology to generate captions in real-time. These software solutions utilize complex algorithms to transcribe spoken language into text and display it as it’s spoken.

While achieving the same 99% accuracy as traditional captioning isn’t yet possible, but AI subtitle generators have significantly improved accuracy rates, reaching around 96-97%. These solutions can be used on various devices like laptops, smartphones, and tablets, and they are compatible with different operating systems, including Windows, Mac OS, and Linux.

Additionally, there are web-based real-time captioning solutions available, such as live captioning on Chrome, allowing users to benefit from real-time captions without the need to install additional software.

What Is the Difference Between AI Real-time Captions and Closed Captions?

Let’s have a look at the basic difference between live captions and closed captions. Closed captions are meant for content that’s recorded in advance, while live captions are for real-time situations like webinars. It’s essential to understand that live captions are a subcategory or subset of closed captions. This means viewers can choose to enable or disable them as needed during live broadcasts. In a nutshell, closed captions are suitable for pre-recorded video content, while live captions cater to live events and can be turned on or off as required.

7 Ways How AI Is Used in Live Event Captioning

AI and machine learning in subtitling is proudly used in a multifaceted manner, enabling more accurate and efficient subtitling. Here’s how AI is utilized in this process:

  1. Automatic Speech Recognition (ASR): AI-powered ASR systems are prerequisites for real-time subtitling. They convert spoken language into text by recognizing and transcribing spoken words. These systems use neural networks and deep learning to improve instant transcription accuracy, making them capable of handling various accents and languages.
  2. Context Analysis: AI algorithms analyze the context of the content, considering preceding and succeeding dialogue to enhance the accuracy of subtitles. This contextual understanding helps in providing coherent and meaningful live captions.
  3. Language Translation: For content in languages other than the source language, AI can automatically translate spoken words into the viewer’s preferred language in real-time. This feature is instrumental for global audiences and boosting engagement.
  4. Speaker Identification: AI can distinguish between different speakers in a conversation, attributing the correct text to the corresponding speaker. This ensures that viewers can follow who is saying what.
  5. Adaptation to Environmental Factors: AI algorithms and machine learning in subtitling can adapt to background noise and other environmental factors, enhancing the accuracy of subtitles even in challenging conditions.
  6. Continuous Learning: AI systems learn from user corrections and feedback, continually improving their accuracy over time.
  7. Customization: AI allows personalized settings, such as text size and color, to cater to individual user preferences.

AI plays a significant role in real-time subtitles by transcribing spoken words accurately, providing context, translating languages, identifying speakers, and adapting to various environmental factors. This technology continues to evolve, making content more accessible and inclusive for a diverse range of audiences.
