How do you use AI tools to generate or improve alt text and captions?

I would also included graphs and images containing text to this definition. I’d also avoid combining alt text and captions within the same paragraph as they are completely different things. Also refer to them as closed captioning as they can be configured by a person… captions are not really used with a screen reader.

Usar um modelo de IA ou redes neurais pré-treinados específicos para as tarefas, como reconhecimento de objetos, análise de sentimentos ou geração de texto. Envolve treinamento e teste do modelo. Alimentar os dados de entrada ao modelo e ajustar seus parâmetros para que ele possa aprender a gerar ou melhorar as legendas otimiza vários processos viabilizando uma comunicação eficiente. É importante ressaltar que o uso de ferramentas de IA para gerar ou melhorar texto alternativo e legendas pode exigir conhecimentos básicos de programação e aprendizado de máquina. Além disso, é fundamental seguir as boas práticas éticas e legais ao usar essas ferramentas, respeitando os direitos autorais e a privacidade dos dados.

Um grande benefício das IA no meu ponto de vista são as grandes oportunidades de tornar conteúdos acessíveis e inclusivos. Utilizamos a IA em nossa ferramenta de acessibilidade sites que tem o recurso de compreensão contextual, OCR e tecnologias de reconhecimento de imagem AI para abordar os requisitos complexos necessários para o leitor de tela e ajustes de navegação do teclado. Desta forma reduzindo boa parte do trabalho realizado manualmente, com projetos longos, complexos e onerosos.

I agree further use cases will include language translation as well as alternative formats for neurodiverse people. Closed captions are used by everybody and studies show they are often used by people who do not have a disability too.

To effectively use AI tools for generating alt text and captions, ensure adherence to WCAG 2.0 guidelines, which require all non-text content to have accurate and meaningful text alternatives. This enables people with disabilities to engage with content comparably to others. When using AI for alternative text, don't solely depend on its suggestions; verify that they meet the content's intended purpose. Descriptions should be contextually relevant, providing a seamless and inclusive experience. Doing this ensures an equivalent level of understanding and interaction for all users, regardless of abilities.

There are also international guidelines such as the web content accessibility guidelines that specifically calls out the vital use of non text alternatives and closed captioning. Some countries such as Canada are required by law to provide multiple languages such as French and English.

In my optioning we should not at this point heavily rely on AI generated captions and alternative text as it can often be inaccurate, Bias and lead to situations where content become more inaccessible. I believe AI could can benefit accessibility however I would always advise a manual check to ensure accuracy. Also use the use of AI will have an effect on our knowledge as people begin to rely solely on automation and do not acquire the skills needed to create inclusive content.

I agree with this, also as technologies continue to evolve such such as VR and AR we need to ensure that content is accessible in an augmented world.

Moi qui utilise une synthèse vocale pour prendre connaissance des textes alternatifs présents sur les visuels, je recommande vivement de ne pas utiliser d’abréviations, de faire des phrases courtes et de vulgariser au maximum pour toucher un public large.
