“NXP’s introduction of the i.MX RT106L MCU-based offering makes it possible for original equipment manufacturers (OEMs) to deliver low latency, hands-free experiences to their customers,” said
Integrated machine-learning-based automatic commands recognition (ACR) technology is achieved locally on the device in partnership with Snips, a pioneer in embedded voice recognition software for businesses, products and services. The solution is built on NXP’s i.MX RT106L crossover MCU running FreeRTOS, enabling low latency detection of local commands and wake word(s). The solution also embeds necessary digital signal processing capabilities for far-field operation.
Out of the box, the i.MX RT106L MCU-based solution includes a wake word and four sets of example local commands, enabling developers to quickly create proof of concepts (PoC) to demonstrate and evaluate the addition of voice control to their products. Following successful PoC, OEMs can work directly with NXP to generate models specific to their application.
“Combining the power of Snips Commands with NXP’s i.MX RT106L crossover MCU-based local commands solution represents a breakthrough in price and performance, making it easy for brands and manufacturers of smart home and smart appliance products to add voice control without requiring cloud connectivity, removing the need for Wi-Fi and eliminating users’ privacy concerns,” said
NXP’s i.MX RT106L MCU-based local commands solution provides OEMs with a turnkey ACR offering and a far field AFE required to implement local voice control. Additionally, the solution’s noise suppression, echo cancellation and beam-forming capabilities make it possible to use in acoustically difficult environments. The i.MX RT106L bundles all the necessary voice related capabilities and software at no extra cost. The result is a total system cost that’s less than half that of microprocessor- and/or DSP-based alternatives.
NXP is now engaging with OEMs to provide early access to the evaluation and development kit for this solution, and broad market availability is expected to begin in Q1 2020.
