Voice Control and Communications Software Overview
Full-service, comprehensive suite of customizable voice enablement technologies for accelerated voice-based application development.
Voice Intelligent Technology
Voice Intelligent Technology (VIT) is a comprehensive local voice user interface software suite from NXP. The VIT suite includes several engines, including the free-to-use wake word engine (WWE) and a free Voice Command engine (VCE), as well as a premium Speech to Intent (S2I) engine.
The wake word and Command Engines are supported by online model creation tools, which allow users to quickly create customized model files according to their desired voice user experience.
VIT's S2I engine is designed to be more like natural language understanding, wherein a user can use a broad range of voice commands to get the desired action from the device. Unlike the VCE, which requires a specific voice command (for example, a user must say “Lights On”), S2I allows users to speak in a natural way to get the desired action (for example, “I need more light” or “It's too dark in here” or “Please turn on the lights”, etc.). The S2I engine will be supported with online model creation tools in mid-2024. In the meantime, qualifying customers will be supported by NXP's professional voice services team to create customized voice user experiences.

NXP Voice Processing Software FAQs
How do I get started with VIT?
VIT wake word and Voice Command Engine can be accessed through online tools and our MCUXpresso SDK. For VIT Speech to Intent, please contact us at voice@nxp.com with your specific requests.
Does NXP have voice software application examples?
Yes, visit our application software pack page or our Application Code Hub. You can also view demo videos showcasing our voice software.
What is the difference between voice UI and voice communications?
Voice UI refers to “voice-first” devices that use voice as a user interface. NXP's Voice UI software technologies are VIT, VoiceSpot and VoiceSeeker.
Voice communications refer to two-way person-to-person communication using voice; i.e., telephony. NXP's Voice communications software technology is Conversa.
What is the difference between VoiceSpot and VIT? When should you use one versus the other?
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 ultralow 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.
What is VoiceSeeker and how do you use it?
VoiceSeeker is a multi-microphone beamforming audio front end signal processing solution for voice user interfaces. VoiceSeeker discriminates between signal and noise and is especially effective in far-field, reverberant conditions. VoiceSeeker is offered in a standard free-to-use option and a premium option. VoiceSeeker without AEC is freely available via NXP's MCUXpresso SDK and integrates easily with VoiceSpot or VIT. The premium VoiceSeeker option includes an acoustic echo canceler (AEC) and is available via controlled distribution from NXP. VoiceSeeker is frequently used in far-field voice control applications like smart speakers and home controllers but can also be used in the mid- and near-field where interfering noise needs to be cancelled.
