Mobile speech SDK selection and download
Download NUI mobile SDK packages for Model Studio speech services. Select a package by platform and application ID, and review compatibility requirements and release notes.
Select a package
The version number, such as 2.7.4, identifies an SDK release. The application ID, such as 037 or 047, identifies a package feature set.
NoteV2.7.3 and earlier do not support the new Model Studio workspace domains. Using these domains causes SDK initialization or connection failures. Use the following legacy endpoints:
- China (Beijing):
wss://dashscope.aliyuncs.com/api-ws/v1/inference - Singapore:
wss://dashscope-intl.aliyuncs.com/api-ws/v1/inference
V2.7.4 and later support the new workspace domains.
V2.7.4 and V2.7.5 packages with the following application IDs support all of these Model Studio cloud capabilities:
- CosyVoice speech synthesis
- Sambert speech synthesis
- Fun-ASR speech recognition / recorded speech recognition
- Gummy speech recognition / translation
- Qwen-Livetranslate-Realtime audio translation
- Qwen-Audio-Realtime conversations
On-device capabilities vary by application ID as follows.
| Application ID | On-device speech synthesis | On-device wake word detection | On-device acoustic echo cancellation and voice activity detection |
|---|---|---|---|
039 | Supported | Supported | Not supported |
038 | Supported | Not supported | Not supported |
037 | Not supported | Not supported | Not supported |
