The Rise of AI in Accessibility Services

Why is Accessibility Services a Mandate?

People with disabilities are not left behind by hindsight like the olden days. Since post-modern industrialization, empathy and emphasis toward people with disabilities have risen. This act resulted in building technologies that suit the needs of the disability spectrum, largely benefitting the community.


In the last 4 decades, there have been multiple mandates that establish a strong cause for extending the support. These actions pushed the people to follow a certain set of guidelines to make and provide an equal platform to the disabled in every arena.


ADA stands for the Americans with Disabilities Act. It is a federal law in the United States that was signed into law in 1990 and is designed to prohibit discrimination against individuals with disabilities. The ADA covers a wide range of areas and has several key provisions and uses


The ADA prohibits discrimination against qualified individuals with disabilities in all aspects of employment, including hiring, promotion, compensation, and termination. It also requires employers to provide reasonable accommodations to enable employees with disabilities to perform their job duties.

Public Accommodations

ADA Title III requires businesses and organizations that are open to the public, such as restaurants, stores, and theaters, to provide equal access to individuals with disabilities. This includes physical accessibility, such as wheelchair ramps and accessible restrooms, as well as provisions for communication access, such as sign language interpreters or captioning for the deaf and hard of hearing.

State and Local Government Services

ADA Title II prohibits discrimination by state and local governments and their agencies, including public transportation systems, in all services, programs, and activities. It ensures that individuals with disabilities have equal access to government services and facilities.


The ADA includes provisions related to telecommunications, ensuring that people with disabilities have access to the same telecommunications services as everyone else. This includes requirements for relay services for individuals with hearing or speech impairments.


ADA Title II and Title III address accessibility in transportation services. This includes accessible public transportation, such as buses and trains, as well as requirements for accessibility in private transportation services, like taxis and shuttles.

Public Services

The ADA prohibits discrimination in all aspects of public services, including libraries, parks, and recreational facilities, to ensure that individuals with disabilities can participate fully in public life.


The ADA includes provisions ensuring that students with disabilities have equal access to educational programs and services at all levels, from preschool through post-secondary education.


While the ADA primarily focuses on public accommodations, the Fair Housing Act (FHA) also prohibits discrimination against individuals with disabilities in housing-related matters, including renting, buying, or obtaining financing for housing.

Design Standards

The ADA includes detailed design standards for accessibility in new construction and alterations. These standards provide specific guidelines for ensuring that buildings and facilities are accessible to individuals with disabilities.

Video Standards

The Americans with Disabilities Act (ADA) mandates that video content be accessible to individuals with disabilities. Key requirements include providing closed captions for the hearing impaired, audio descriptions for the visually impaired, accessible video players and interfaces, and compliance with web accessibility standards (such as WCAG). Non-compliance can lead to legal consequences. Ensuring ADA compliance in video consumption is crucial for inclusivity and legal adherence.


The ADA has been instrumental in promoting equal rights and opportunities for individuals with disabilities in the United States. It has led to significant improvements in accessibility and inclusivity in various aspects of life, making it easier for people with disabilities to participate fully in society. It serves as an important legal framework for addressing and preventing discrimination based on disability.

What are Closed Captions?

Closed captions are a text-based representation of the audio content in a video. They include not only the spoken words but also relevant sounds and music cues, making it a comprehensive tool for conveying audio information to viewers who may have difficulty hearing or understanding the spoken language. Closed captions are typically displayed on the screen in real-time, synchronized with the video, and provided with a preferability to switch On/Off.

Types of Closed Captions:

Live/Real-Time Captions

Live/Real-time captions are essential for live events, news broadcasts, and live webinars. Captioners and Stenographers type the captions in real time, and they are immediately displayed on the screen. This helps the deaf or Hard of Hearing individuals to get the hang of the content being discussed.


Multiple virtual connect platforms like Zoom, GoToWebinar, and Google Meet, give a separate integration format for specialized captions.

Offline/ Post Production Captions

Offline captions are prepared in advance and added to pre-recorded videos. Typed at a higher accuracy and synchronized precisely to match the audio. Content creators, Educators, and Trainers can create offline captions during the post-production process and ensure they deliver a perfectly blended video experience.

Open Captions

Unlike closed captions, open captions are permanently burnt into the video, and viewers cannot turn them off. Open captions are commonly seen in movies, television shows, and some online educational videos. 


Also, in recent days, content creators have taken advantage of Open captions to reach a maximum audience as 90% of users prefer watching videos with captions.

Closed Captions

These captions, as the name suggests, are optional and can be turned on or off by viewers as per their preference. This flexibility makes them a versatile choice for a wide range of video content. Closed captions are often seen on YouTube, Netflix, and other streaming platforms.

The Importance of Closed Captions

Closed captions extend far beyond providing accessibility for the deaf and hard of hearing. 

They also benefit non-native speakers who may struggle with spoken language, individuals watching videos in noisy environments, and those who prefer to watch content with the sound turned off. 

Additionally, closed captions can improve comprehension, enhance learning experiences, and even boost SEO by making videos more searchable.

The Evolution of Closed Captions

In history, it has been etched that closed captions are a significant modern discovery. Let’s see how it started. The evolution of closed captions is a fascinating journey that has significantly impacted the way we consume media and has greatly enhanced accessibility for individuals with hearing impairments.


Closed captions are text descriptions of the audio content in a video, movie, or television program. They were initially developed as a tool to aid the deaf and hard-of-hearing community but have since become an integral part of the media landscape. Let’s explore the evolution of closed captions in detail:

Early Attempts in the 1970s

Despite the boom of the television era in the 1950s, the accessibility needs of the deaf and hard of hearing were not addressed properly. As years passed by, the needs arose and the development of the TV Accessibility solutions was started.


Malcolm Norwood, a hearing-impaired and renowned teacher, and the Department Of Education brought together a team in 1971 that included the National Bureau of Standards, the National Association of Broadcasters, ABC, and PBS. They held a National Television Conference in Nashville in December of 1971, which we can say was the birthplace of closed captioning.

There, captioning was first demonstrated to an audience. In the same year, the Caption Center was established in Boston for further establishment.


The first show that aired with Captions was in 1972, it’s called The French Chef, it was open captions with no options to turn it off. This paved the way to consume the content with captions. 

Teletext and Broadcast Captions in the Late 1970s

The next significant development was the use of teletext technology to provide captions. In the United Kingdom, for example, the Teletext system allowed broadcasters to transmit caption data on a separate channel.

This approach made captions more accessible to a wider audience, but it required specialized equipment and was often not synchronized perfectly with the video.

Analog Captioning and VCRs in the 1980s

As the 1980s and 1990s rolled in, analog captioning technologies improved, making it easier for viewers to access captions. VCRs (Video Cassette Recorders) with built-in caption decoders became popular, allowing viewers to watch captioned content without additional equipment.

The Rise of Digital Closed Captions in the 90s

The transition to digital television in the 1990s marked a significant milestone in the evolution of closed captions. Digital closed captioning allowed for more precise timing and formatting of captions, leading to a better viewing experience for those who rely on them.

In the United States, the Telecommunications Act of 1996 mandated that all television sets 13 inches or larger include built-in caption decoders.

Caption Standards and Internet Streaming in the 2000s

With the rise of the internet and streaming services, closed captions became increasingly important for online video content. The WebVTT (Web Video Text Tracks) format and other caption standards emerged to ensure compatibility across various platforms and devices.


Legal regulations, such as the Americans with Disabilities Act (ADA) in the United States, have required online content providers to offer closed captions on their videos, further emphasizing the importance of accessibility.

Automatic Speech Recognition (ASR) and AI

Automatic Speech Recognition

Recent advancements in AI and automatic speech recognition (ASR) technology have enabled the automatic generation of captions. Major tech companies and platforms, like YouTube, use ASR to provide real-time automated captions, making content more accessible and reducing the burden on content creators.

Global Expansion and Multilingual Support

Closed captions have evolved beyond English-speaking countries and are now available in multiple languages. This expansion has increased their utility for international audiences. Additionally, efforts have been made to improve the quality of captions, including better accuracy, synchronization, and customization options for viewers.


At the inception of all Accessibility services, closed captions were the starting point for a visible revolution starting to take place. This boosted the entire industry to come up with a variety of modern solutions to cater to the needs of the impaired.

The Advent of Automatic Speech Recognition

Automatic Speech Recognition (ASR) has its origins dating back to 1952 when Bell Labs introduced “Audrey,” a system designed to recognize spoken digits. Initially, Audrey could only transcribe numbers, but over the next decade, researchers enhanced it to recognize basic spoken words like “hello.”


ASR primarily relied on classical Machine Learning techniques like Hidden Markov Models(HMM). While these methods were once considered the industry standard, their accuracy had reached a plateau in recent years. This stagnation paved the way for new approaches driven by advanced Deep Learning technology, which had also seen significant advancements in fields like self-driving cars.


In 2014, Baidu published a groundbreaking paper titled “Deep Speech: Scaling up End-to-end Speech recognition.” This paper showcased the power of applying Deep Learning research to create state-of-the-art, highly accurate Speech Recognition systems. This publication initiated a renaissance in the ASR field, promoting the adoption of Deep Learning techniques and pushing model accuracy beyond previous limits, approaching human-level performance.


Not only has ASR accuracy seen a substantial increase, but the accessibility of ASR technology has also improved significantly. A decade ago, customers would have had to enter into lengthy and costly enterprise software contracts to license ASR technology.


ASR technology has been playing a significant role in the development and improvement of automatic closed captions. The market for closed captioning services and solutions has been steadily growing due to various factors, including legal requirements for accessibility, the expansion of online video content, and the increasing demand for inclusive media.


This crucial intervention of the decade has shaped up well to make notable changes in the accessibility industry promising various things.
