Amazon Polly supports MP3, The Kevin voice waveforms limits the quality of speech.

Amazon Polly enables you to use either neural or standard voice with the If you are not in one of the four regions where NTTS is supported, only the standard voice engine will be displayed in the console.

A neural network that converts a sequence of phonemes—the most basic units of language—into a sequence of spectrograms, which are snapshots of the energy levels in different frequency bands A vocoder, which converts the spectrograms into a continuous audio signal. Use it to make conversations with chatbots and virtual assistants more natural and engaging, to convert digital texts such as e-books into audiobooks and to upgrade in-car navigation systems with natural voice experiences and more.This release includes significant enhancements since we first The voices sound more robust and natural across a wider variety of user scenarios, achieved by harnessing the following:Runtime performance of the Neural Text-to-Speech engine is near-instantaneous through extensive code optimization with hardware accelerators, applying parallel inference models and model simplifications considering the balance of sound quality and performance. Applying the latest in deep learning innovation, Speech Service, part of Azure Cognitive Services now offers a neural network-powered text-to-speech capability.
