Beyond the Neural Network: The Enduring Utility of Non-AI Text-to-Speech

When we hear computer-generated voices today, we usually think of hyper-realistic, deep-learning models capable of cloning voices, injecting emotional nuance, and breathing natural pauses into dialogue. But long before transformer architectures and neural vocoders dominated the landscape, text-to-speech (TTS) technology was quietly translating text into sound using an entirely different philosophy: pure mathematics, linguistic rules, and pre-recorded audio snippets.
