The British company says the new firmware variants for its XVF3510 voice processor are designed to address the rapidly evolving demands of the far-field voice market, enabling the development of high performance voice-enabled smart products at a low eBOM.
The new purpose-designed algorithms for voice processing introduced in the new XVF3510-UA and XVF3510-INT variants include advanced acoustic echo cancellation (AEC), enabling the detection of voice signals even through high-volume audio interference, combined with interference cancelling (IC), working intelligently to remove static point noise and ignoring audio from other devices. Developers will also benefit from advanced noise suppression, removing both stationary and non-stationary diffuse noise sources, plus automatic delay estimation control (ADEC) that adjusts signal latency to guarantee optimal AEC performance, and automatic gain control (AGC), tuning output channel level for optimum results.
The new solutions also support real-time system control and parametrization, monitoring and adapting algorithm control, plus system configuration and GPIO. Requiring just two microphones, the XVF3510 is optimized for audio visual products, smart home devices and appliances, health and fitness solutions and conference calling.
"The far-field voice market is expanding and evolving at great pace, and we need to be able to guarantee that our products can remain integral to rapidly diversifying use cases across the field. With the introduction of these two new firmware releases, the XVF3510 strikes that sweet spot between price and performance, equipping engineers with the flexibility they need to drive fresh ideas and create new value for end users,” says Mark Lippett, CEO, XMOS.
