XK-VOICE-L71 Voice Reference Design Evaluation Kit

XMOS' XK-VOICE-L71 voice reference design evaluation kit is versatile and can be utilized in two primary ways including functioning as a Raspberry Pi HAT, allowing for seamless integration with an example Alexa Voice Service (AVS) client. Alternatively, the XK-VOICE-L71 is suitable as a standalone device, serving as a USB accessory connected to a host system. This flexibility makes the kit a valuable tool for various voice-enabled application developments.

The xcore-voice solution is a comprehensive package that is based on the xcore platform hardware, software, and tools. This solution offers voice pipeline example designs utilizing XMOS' industry-proven audio front-end, which includes far-field voice processing capabilities and supports third-party ISV voice algorithms. These algorithms include features such as an automatic speech recognition (ASR) engine for keyword detection and a local command dictionary. This versatility allows for a broad range of applications and end products such as smart TVs, set-top boxes, and smart home appliances, while enabling product designers to quickly and cost-effectively create “across-the-room” voice interfaces while ensuring optimal audio quality.

xcore.ai is the third generation of the xcore processor architecture, delivering unprecedented flexibility through a combination of general-purpose DSP (fixed and floating point), AI (32b, 8b, and 1b networks), and IO processing (nano-second resolution). Unlike traditional SoCs, xcore systems can be architected in software, avoiding the usual lengthy hardware development schedules associated with custom silicon. The example designs in the xcore-voice solution leverage the processor capabilities through the xcore platform software which provide building blocks for the development of a wide variety of applications. The xcore platform software supports development using the C programming language, "on-the-metal" and/or within FreeRTOS. The example designs are delivered as source code, or pre-compiled and can be evaluated quickly on the XK-VOICE-L71 voice evaluation kit.
