Edge Trigger Word Detection
Edge Trigger Word Detection (ETWD) Engine determines the presence of a pre-specified trigger word in voice input by the user.
The ETWD engine is an embedded-based recognition engine that can be used by selecting either TWD (Trigger Word Detection) or NTWD (Neural Trigger Word Detection). The details are as follows.
Supervised learning with re-recorded data from the target product for loading into the product is finally optimized by over-fitting.
Since it is a structure that learns a DNN-based phoneme unit model independent of the target start word and transfers the target actuation word, the learning time is relatively reduced and it has strong characteristics against product/channel/environment deviation. The NTWD engine uses a neural network-based algorithm, so it requires a lot more computation than the TWD engine, so it is necessary to check whether the target is operating or not.
ETWD Engine by LG AI Platform supports the following features:
|Support for various trigger words||
hilg, heycloi, airstar
Supports Korean and English languages
ETWD Engine combines embedded trigger word detection with server-based trigger word detection.
Examples of Use
The ETWD function can be used in all devices equipped with a speech recognition function. This engine allows a user to initiate speech recognition without touching the device.
- Devices with a virtual assistant
You can control the device by the voice from a mobile device equipped with an AI virtual assistant system.
- Home appliances capable of speech recognition
It can be applied to operate home appliances with voice recognition-capability.
- Robot control
Operate and control robots using natural language commands.
