Limited Access to Custom Neural Voice
As part of Microsoft's commitment to responsible AI, Custom Neural Voice is designed with the intention of protecting the rights of individuals and society, fostering transparent human-computer interaction, and counteracting the proliferation of harmful deepfakes and misleading content. For this reason, Custom Neural Voice is a Limited Access feature available by registration only, and only for certain use cases.
Approved registrants for Custom Neural Voice will also get access to deploy and use a Custom Neural Voice Lite voice model. Custom Neural Voice Lite is a project type in public preview that allows you to record 20-50 voice samples on Speech Studio and create a lightweight custom voice model for demonstration and evaluation purposes. Both the recording script and the testing script are pre-defined by Microsoft. The synthetic voice model created using the Custom Neural Voice Lite project could be deployed and used at your discretion, after you register and full access to Custom Neural Voice is granted.
As a Limited Access feature, Custom Neural Voice requires registration. Only customers managed by Microsoft, meaning those who are working directly with Microsoft account teams, are eligible for access. Customers who wish to use this feature are required to register by submitting a registration form. The use of Custom Neural Voice is limited to the use case selected at the time of registration. Microsoft may require customers to re-verify this information.
The Custom Neural Voice capability is made available to customers under the terms governing their subscription to Microsoft Azure Services (including the Service Specific Terms). Please review these terms carefully as they contain important conditions and obligations governing your use of Custom Neural Voice. For example, these terms include, but are not limited to, the following obligations:
Voice talent and approved use cases. Customer will need to warrant that it has obtained explicit written permission from voice talent prior to creating a voice model, which includes sharing the Disclosure for Voice Talent with the voice talent and may only use the custom voice model for use cases selected during registration.
Implementation requirements. As outlined in our Code of Conduct here, customer must not use its custom voice model for certain prohibited uses and must also agree that when deploying the custom voice model, its implementation will disclose the synthetic nature of the service to users and support a feedback channel that allows users of the service to report issues and share details with Microsoft.
Microsoft's additional processing and use of voice talent data. Before Customer can train a custom voice model, we may require customers to upload an audio file to the Speech Studio with a pre-defined statement from the voice talent acknowledging customer's use of Voice Talent's voice to create a synthetic voice. As a technical safeguard intended to help prevent misuse of this service, Microsoft reserves the right to use Microsoft's speaker recognition biometric identification technology on this recorded statement and verify it against the training audio data in order to provide some assurance that the voices come from the same speaker. Microsoft will also continue to retain this audio file and the custom voice model to protect the security and integrity of our services. Customer is responsible for ensuring all necessary permissions are received from its voice talent for these purposes.
