@ohos.ai.intelligentVoice (Intelligent Voice)

The intelligentVoice module provides the intelligent voice enrollment and voice wakeup functions.

Its functions are implemented by:

• IntelligentVoiceManager: intelligent voice manager class, which declares the functions provided by the module. Currently, voice enrollment and voice wakeup are supported. Before developing intelligent voice functions, call getIntelligentVoiceManager() to check whether they are supported.
• EnrollIntelligentVoiceEngine: class that implements voice enrollment. You need to perform voice enrollment before using voice wakeup.
• WakeupIntelligentVoiceEngine: class that implements voice wakeup. You need to perform voice enrollment before using voice wakeup.

NOTE

• The initial APIs of this module are supported since API version 10. Newly added APIs will be marked with a superscript to indicate their earliest API version.

• The APIs provided by this module are system APIs.
