Neural text-to-speech models use deep neural networks to generate speech waveforms directly from text inputs.
Earlier versions of Siri relied heavily on concatenative speech synthesis using recorded audio segments. By 2018, Apple introduced neural text-to-speech systems powered by deep learning. Neural synthesis allowed smoother intonation and more natural prosody. Models were trained on large datasets of recorded human speech. Machine learning captured subtle variations in tone and rhythm. This advancement reduced robotic artifacts in responses. Speech output became dynamically generated rather than assembled from fragments. Conversational realism increased measurably. Intelligence sounded less mechanical.
