Microsoft Custom Neural Voice

What Microsoft Custom Neural Voice is
Microsoft Custom Neural Voice is a web-based service for professional custom voice model training, hosting, and speech synthesis. Its plans separate those parts of the workflow: Voice model training covers professional voice model training, Endpoint hosting covers deployed custom voice models, and two synthesis plans provide real-time and batch speech generation. Professional voice synthesis offers both modes, while Neural HD professional voice synthesis offers them in Neural HD. The service uses professional cloning rather than instant cloning, and it includes pronunciation controls. API access and commercial use are supported, making it relevant to teams that need to connect voice synthesis to other systems or use it commercially. The service is accessed on the web through Microsoft’s Azure AI Speech product information. Pricing is paid, and the listed plan prices are not provided here. Buyers can identify the relevant service area—training, hosting, or synthesis—before choosing among the plans.
