You are working on a multilingual public announcement system. Which AI task will you use to implement it?

A multilingual public announcement system needs to convert written text (the announcement message) into audible speech that can be broadcast. The "Text to speech" (TTS) AI task is designed specifically for this purpose, synthesizing human-like speech from text input. OCI AI Speech service provides TTS capabilities that support multiple languages and voices, directly addressing the requirements of the described system.

A. Speech recognition converts spoken audio into text, which is the reverse of what is needed for an announcement system.
B. Text summarization condenses a longer text into a shorter version, which is not the primary function of an announcement system.
C. Audio recording is the process of capturing sound; it does not generate speech from text for an announcement.
