Whispers from the Machine: The Craft of Text-to-Speech Without AI

In an era dominated by hyper-realistic, generative neural models capable of cloning any voice with a three-second sample, it is easy to forget that text-to-speech (TTS) once relied on logic rather than learning. Long before deep learning and transformer architectures breathed simulated emotion into silicon, engineers built talking machines using math, rules, and audio splicing.
