Text-to-Speech (TTS)

Text-to-Speech (TTS) is a technology that converts written text into spoken words.

Text-to-Speech (TTS) technology transforms written text into spoken audio. It uses natural language processing (NLP) to interpret the text and a speech synthesis engine to generate human-like speech. TTS systems have advanced significantly, producing more natural and expressive voices. They are used in a variety of applications, from accessibility tools for the visually impaired to virtual assistants like Siri and Alexa.

Examples

  • Using TTS for audiobook narration.
  • Integrating TTS in GPS navigation systems for spoken directions.
  • Employing TTS in customer service chatbots to provide audio responses.

Common misconceptions

  • TTS systems do not simply record human voices; they generate speech programmatically.
  • TTS is not limited to monotone or robotic voices; modern systems can express emotions.
