Notes
- After opening some algorithm functions, the number of words may be less than the annotated value.
- After the external IOT module is added, the number of Support words varies according to different module models.
- CI1301, CI1302, and CI1312 After the local voiceprint recognition function is enabled, local speech recognition cannot be supported at the same time. To Support local voiceprint recognition and local speech recognition at the same time, use CI1303 and CI1306.
