Contribution grade

Text-to-speech systems · Human-designed research method or resource

Reference score140,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Integrated a recurrent character-to-mel predictor with a modified WaveNet vocoder and evaluated compact acoustic conditioning choices.

Scientific scope

Integrated a recurrent character-to-mel predictor with a modified WaveNet vocoder and evaluated compact acoustic conditioning choices. Explicitly inherits Tacotron and WaveNet. Acquired delta is the neural two-component synthesis integration, not invention of either component. Selected mean-opinion scores do not prove all speech indistinguishable from human recordings.

Evidence

The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof. Explicitly inherits Tacotron and WaveNet. Acquired delta is the neural two-component synthesis integration, not invention of either component. Selected mean-opinion scores do not prove all speech indistinguishable from human recordings.
