This text describes how to leverage the HiBrainy TTS API to build a web service for generating speech audio files from text messages using Python and Flask. The process involves signing up for a free RapidAPI account, subscribing to the HiBrainy TTS API, testing the subscription, building a web service using Flask, defining three API endpoints (/tts/create, /tts/list, and /tts/<ID>) for creating, listing, and retrieving audio clips, respectively, and rendering HTML templates for displaying the results. The application allows users to generate and listen to audio clips of text messages.
