The document compares XMOS voice products, specifically their smart microphones and microphone arrays. The smart microphone is the XVSM-2000 which is part of the xCORE-VOICE family, supports up to 16 microphones, and includes voice DSP functionality. The microphone array is the XUF216 which is part of the xCORE-200 family, supports up to 32 microphones, and provides fully programmable DSP for custom applications. Both are suitable for applications involving far-field voice capture, digital assistants, and more.
