What is AI?
AI stands for Artificial Intelligence, enabling machines to mimic human intelligence for tasks such as learning, problem-solving, and decision-making.

This sample demonstrates the integration of Text-to-Speech with the AI AssistView component, enabling users to convert AI-generated responses into spoken audio via the browser’s Web Speech API for voice-based interaction.

Key Features:

  • The ResponseToolbar includes a custom Read Aloud button that extracts plain text from the AI response and uses the browser's SpeechSynthesis API to vocalize it.
  • The SpeechSynthesisUtterance interface is used to manage speech playback, including toggling between play and stop states.
  • The AssistViewToolbar adds a right-aligned Refresh button to clear previous prompts.
  • Responses are streamed dynamically using the UpdateResponseAsync method, and the ScrollToBottomAsync method ensures the latest response is always visible.
