==== SSML ====

After our initial exploration of various mainstream TTS products, the conclusion was that the voices sound quite convincing and pleasant, but the intonation is unnatural and does not properly emphasize the right words. We sought the solution to this problem in Speech Synthesis Markup Language (SSML). This is a way to include markings in de source text to indicate emphasis, pauses and other things that can improve the speech. Our idea was to use ChatGPT to add these markings to the source text, so that a TTS product can use this to improve its speech pattern.
