Knowles audio processors feature high-precision voice wake up and voice ID keyword recognition to wake up the system by triggering phrases
Knowles IA61x Voice Wake Up SmartMics mics mics uses 43 MHz Tensilica audio optimization DSP and high performance acoustic SiSonic MEMS technology in a single micromicrophone package. The integrated programmable DSP can be used with third-party algorithms to enable full customizability (IA611). The solution pushes system performance towards ultra-low power consumption with its customized kernel design and optimized instruction set. It speeds time to market with its complete hardware, software, firmware, code and toolkits.
Features
● High precision, low power voice wake up and voice ID keyword recognition, can wake up any system from the trigger phrase
● The onboard buffer enables seamless voice wake up operation
● Ultra-low power always-on audio activity Detector (AAD)
● Beamforming for enhanced sound quality
● An open developer platform using the SDK
● High performance SiSonic MEMS with ±1 dB matching sensitivity, 65 dB SNR and 135 dB SPL acoustic overload points
● Application memory size: 168 KB
Applications
● Smart phone
● Wearable device
● Tablet computer
