Prerequisites from Mixīefore developing your TTS gRPC application, you need a Nuance Mix project. This release supports version v1 of the synthesizer API and v1beta1 of the storage API. NVC supports Protocol Buffers version 3, also known as proto3. It uses HTTP/2 for transport, and protocol buffers to define the structure of the application. GRPC is an open source RPC (remote procedure call) software used to create services. An HTTP API for synthesis is also available.Īn additional gRPC storage protocol can upload synthesis resources to cloud storage.
The gRPC synthesizer protocol provided by NVC can request synthesis services in any of the programming languages supported by gRPC. It works with voices in many languages and locales, with choices of gender and age. TTS as a Service lets you request speech synthesis from NVC engines running on Nuance-hosted machines.
NVC works with Nuance Vocalizer for Enterprise (NVE) and Nuance voice packs to generate speech. Nuance TTS (Text to Speech) as a Service is powered by the Nuance Vocalizer for Cloud (NVC) engine, which synthesizes speech from plain text, SSML, or Nuance control codes. Different alphabet gives no audio, no error.
