VoiceSpot is a very accurate, highly optimized wake word and acoustic event detection engine. It is based on deep learning neural network techniques and requires large datasets for training. VoiceSpot is appropriate for customers who need the highest response rates with the fewest false alarms and is also appropriate for customers who need to run in ultra-low power states while waiting for the voice / acoustic trigger.
VIT software suite is built on phoneme-based automatic speech recognition technology. This technology maps spoken phonemes (the basic building blocks of speech) into words, which can then be recognized as wake words and commands and then, transformed into intents and actions. Because VIT is based on phonemes, it is possible to create wake words and command models quickly with a keyboard and NXP’s online model creation tools. VIT Wake Word and Voice Command Engines are appropriate for customers who want to build custom wake words and voice commands independently or those who want to quickly experiment with voice as a user interface. VIT Speech to Intent is for customers who want to create a natural language understanding like experience on edge processors without the use of cloud connectivity and cloud ASR transcription services
