-Azure AI Speech provides two custom neural voice (CNV) project types: CNV lite and CNV professional. 
+Custom voice lite is a project type where can demo and evaluate custom voice before investing in professional recordings to create a higher-quality voice. No application is required for demo and evaluation purposes. However, Microsoft restricts and selects the recording and testing samples for use with custom voice lite. You must apply for full access to professional voice fine-tuning in order to deploy and use the custom voice lite model for business purpose. In that case, request access on the [intake form](https://aka.ms/customneural).
 
-- Custom neural voice (CNV) professional allows you to upload your training data collected through professional recording studios and create a higher-quality voice that is nearly indistinguishable from its human samples. CNV professional access is limited based on eligibility and usage criteria. Request access on the [intake form](https://aka.ms/customneural).

+> [!NOTE]
+> Custom voice lite is only available in the [Speech Studio](https://aka.ms/speechstudio/customvoice). It isn't available through the Azure AI Foundry portal, REST API, or SDKs.
 
-With a CNV lite project, you record your voice online by reading 20-50 pre-defined scripts provided by Microsoft. After you've recorded at least 20 samples, you can start to train a model. Once the model is trained successfully, you can review the model and check out 20 output samples produced with another set of pre-defined scripts.
