What fidelity level and primary technique characterized voice cloning technology Post-2015?

Answer

High fidelity (Near-human, expressive) achieved via Neural TTS / Deep Learning

The technological timeline shows a clear progression in quality corresponding with the underlying methods used. For the period categorized as Post-2015, the primary technique shifted entirely to Neural TTS, which relies on Deep Learning architectures. This integration led directly to a fidelity level described as High, meaning the resulting audio is capable of being near-human and expressive. This marks the era where the output quality became nearly indistinguishable from reality, a massive leap from the low, robotic quality of the pre-2000s concatenative methods.
