Text-to-speech, abbreviated as TTS, is a type of assistive technology that reads digital text aloud. The technology behind TTS has evolved over the last few decades. It is now possible to produce very natural-sounding speech that includes changes to pitch, rate, pronunciation, and inflection.

TTS is characterized by its convenience and accessibility feature that helps people who need additional assistance to hear text that's printed on-screen. The scene we often see the adoption of TTS technology is in smart assistants, like Amazon's Alexa and Apple's Siri. When you speak to ask these assistants, they will “reply” you, specifically read to you from a predetermined library of words and phrases. TTS technology is the premise for these system to operate.

Generally speaking, TTS has distinctive benefits in the following three aspects.

  • Accessibility: It provides access to people who have learning disabilities as well as literacy issues by offering an alternative way to get information.

  • Enhanced Learning: By allowing users to see text and hear it read aloud simultaneously, it can help improve comprehension, recall, vocabulary skills, motivation, and confidence.

  • Mobility & Freedom: It can turn any digital content into a multimedia experience, so people can listen to news, blog articles, or even a PDF document, on-the-go or while multitasking.
