Neural TTSaaS offers text-to-speech services powered by Nuance Vocalizer for Cloud (NVC) and the neural Text-to-Speech feature of Microsoft Azure Cognitive Services for Speech. Working with Microsoft neural voices, Neural TTSaaS synthesizes speech from plain text or SSML input.

The gRPC synthesizer protocol provided by Neural TTSaaS can request synthesis services in any of the programming languages supported by gRPC.

gRPC is an open source RPC (remote procedure call) software used to create services. It uses HTTP/2 for transport and Protocol Buffers version 3 (“proto3”) to define the structure of the application.
