Text to speech (TTS) technology has revolutionized how users interact with web content. HTML5, with its advanced features, allows web developers to integrate TTS capabilities, enhancing accessibility and user experience.
What is Text to Speech?
Text to speech is a form of synthesis that converts text into spoken words. This technology is widely used in various applications to aid those with visual impairments or reading difficulties.
The Core of HTML5 TTS: SpeechSynthesis Interface
The SpeechSynthesis interface in HTML5 is a part of the Web Speech API, enabling developers to incorporate voice capabilities in web applications.
Utilizing the SpeechSynthesis Interface
To use SpeechSynthesis in HTML5, JavaScript plays a crucial role. The new SpeechSynthesisUtterance object allows customization of the speech output, including pitch, rate, and volume.
