 | The standard, or "traditional," method of custom voice breaks down spoken language into phonetic snippets that can be remixed and matched using classical programming or statistical methods.  | Custom neural voice synthesizes speech using deep neural networks that have "learned" the way phonetics are combined in natural human speech rather than using classical programming or statistical methods.|
-| Custom voice requires a large volume of voice data to produce a more human-like voice model. With fewer recorded lines, a standard custom voice model will tend to sound more obviously robotic. |The custom neural voice capability enables you to create a unique brand voice in multiple languages and styles by using a small set of recordings.|
