The NUI SDK supports features such as speech recognition, speech synthesis, and wakeup detection. You can select a version based on your business needs and integrate it into your mobile app.
The connection URL configured in the SDK code does not yet support Model Studio's new workspace domain (in the form wss://{workspaceId}.maas.aliyuncs.com/api-ws/v1/inference). Using this domain causes SDK initialization or connection to fail. Use one of the following legacy domains instead:
China North 2 (Beijing): wss://dashscope.aliyuncs.com/api-ws/v1/inference
Singapore: wss://dashscope-intl.aliyuncs.com/api-ws/v1/inference
This document will be updated once a future SDK version supports the new workspace domain.
