Title:
IMPROVING EMBEDDED VOICE RECOGNITION DEVICES
Document Type and Number:
WIPO Patent Application WO/2019/224434
Kind Code:
A3
Abstract:
The invention relates to methods for improving voice recognition, implemented by a stand-alone information processing device, providing for embedded voice recognition via a dedicated human-machine interface, based on the optimisation of the three essential components, which are: an acoustic model for automatic speech recognition (MA) using an artificial neural network, a language model (ML), and a natural language processing engine (NLU) that must be able to function completely autonomously and efficiently even considering the limited storage capacities and computational power that the connected objects and pico-computers provide.
