What Microsoft Custom Neural Voice is
Microsoft Custom Neural Voice is a web-based Azure AI Speech service for professional custom voice workflows. Its listed plans separate speech synthesis, model training, and hosting. Professional voice synthesis supports real-time and batch synthesis, while Neural HD professional voice synthesis provides those same modes with Neural HD identified in the plan name. Voice model training covers professional voice model training, and Endpoint hosting covers hosting deployed custom voice models. The service supports commercial use and API access, with pronunciation controls available for voice output. Its cloning method is professional; instant cloning is not supported. Pricing is paid, but no prices are listed for the plans. The separate plan structure lets organizations identify whether they need synthesis, training, hosting, or a combination of those services. Microsoft presents the product through its Azure AI Speech documentation, and the service is accessed on the web. It is intended for teams creating or deploying custom professional voices rather than users seeking instant voice cloning.
