EveryWord ™ Ultra Far-field Development Kit
ULTRA FAR-FIELD AVS REFERENCE DESIGN KIT FEATURING
CIRRUS LOGIC SOUNDCLEAR® TECHNOLOGY
Developed at Ark X Laboratories by our expert team of engineers, qualified by Amazon AVS and manufactured to exceedingly high standards, the EveryWord™ Dev Kit allows developers to test and validate their own voice-enabled products using an advanced voice solution to mitigate risk, reduce development costs, and accelerate their time-to-market.
Dev Kit Features
Complete production-ready reference design with Cirrus Logic’s SoundClear® technology and NXP i.MX 8 host processor technology
Cirrus Logic’s SoundClear® Technology:
- Increases accuracy and reliability of “Alexa” wake-word triggering and command recognition at far-field distances and in noisy environments
- Preloaded with Amazon Pryon Lite Wake-Word-Engine and accepts Sensory Wake-Word-Engine
- Supports 9+ meters far-field operation with 2, 3, or 4 microphones
- Supports arbitrary mic array geometries, including circular, square, triangular, linear or 3D
- AEC is scalable to mono, stereo, 3-channel, and 5-channel (surround movie or music) use cases
- Supports far-field voice call mode and in-call voice triggering
- Suitable for wall-powered devices or portable battery-operated products with low milliwatt consumption
- 6 mics built-in, ready to be configured for testing circular, square, triangular, and line arrays in 4-mic, 3-mic or 2-mic designs
- AVS compliant LED indicators and mic-mute button. Google Voice compliant mic spacing
- Also includes expansion bus for connecting GPIOs, I2S/TDM, SPI, I2C, and PDM mics
- Web-based firmware control console for simplified interactive operation, mic array selection, acoustic tuning and diagnostics
NXP i.MX 8 host processor technology
