Select and download mobile SDK

Updated at:

NUI SDK supports speech recognition, speech synthesis, wake word detection, and other capabilities. Select a version based on your business requirements and integrate it into your mobile application.

Important

SDK V2.7.3 and earlier do not support the new Model Studio workspace domain in the connection URL, such as wss://{workspaceId}.maas.aliyuncs.com/api-ws/v1/inference. Using this domain causes SDK initialization or connection failures. Use one of the following legacy endpoints instead:

China North 2 (Beijing): wss://dashscope.aliyuncs.com/api-ws/v1/inference

Singapore: wss://dashscope-intl.aliyuncs.com/api-ws/v1/inference

SDK V2.7.4 and later support the new workspace domain.
