Which of the following technologies should be used by a person who is visually impaired to access data from the cloud?

Text-to-voice, also known as text-to-speech (TTS), is an assistive technology that converts digital text into synthesized speech. For a person who is visually impaired, this is a fundamental technology for accessing digital information, including data stored in the cloud. Applications and operating systems use TTS engines, often as part of a screen reader, to read aloud on-screen text, menus, and documents, thereby enabling non-visual interaction with the user interface and content. Cloud services often provide TTS APIs to build accessible applications.

A. Object character recognition: This technology converts images containing text into machine-readable text data. It is a precursor to TTS for non-digital text but does not itself provide audible output.
C. Sentiment analysis: This is a Natural Language Processing (NLP) technique used to determine the emotional tone of text. It is an analytical tool, not an accessibility feature for reading content.
D. Visual recognition: This technology is used to identify and interpret objects, people, and scenes within images or videos. While it can describe visual content, it is not the primary tool for accessing text-based data.

"Improve accessibility for users with disabilities. For example

tools with speech synthesis capabilities can enable people with visual impairments to consume digital content."

2. Microsoft Azure Documentation. (2023

October 26). What is the Speech service?. Microsoft Learn. Retrieved from https://learn.microsoft.com/en-us/azure/ai-services/speech-service/overview. Under the "Text to speech" section

it describes the service's capability to convert text to humanlike synthesized speech

a core function for accessibility tools like screen readers.

CSE 440: Introduction to HCI. Page 21 of the lecture slides discusses screen readers (e.g.

JAWS

VoiceOver) which rely on text-to-speech synthesis as the primary output modality for visually impaired users.
