Hybrid Trigger Word Detection



Hybrid Trigger Word Detection (HTWD) Engine determines the presence of a pre-specified trigger word in voice input by the user.

It performs embedded detection of the trigger word first before server-based detection in order to minimize the misrecognition of trigger words.

Since it takes time to communicate with the server, it can be used without server-based detection for faster recognition speed.

If trigger word detection is successful, HTWD Engine will complete the process. If it fails, HTWD Engine will continue to wait for the user's voice.
