Correctly tuning non-stationary and stationary noise levels These are set appropriately, by default, in the ASR output signal.Typically in speech recognition scenarios, better performance is achieved by the following The enhanced nearend speech output and far-end input signal are typically passed to and obtained from a communication application. An additional output is also provided which is optimised for Automated Speech Recognition (ASR) engines. The algorithm outputs an enhanced mono speech signal representing the desired near-end speech without echo and reverberation, this is optimised for “human” communications, such as VoIP calls. The far-end signal is used as a reference signal for the AEC block which should be an exact duplication of the loudspeaker signal.

For more details on the algorithms please see the document XVF3000/3100 DSP Databrief1.
A high level general application block diagram is shown in Figure 1.

SmartTV supports linear arrays to provide up to 180° coverage and has been developed for far-field voice control in TV and/or video applications. SmartHome supports circular arrays to deliver 360° coverage and has been developed specifically for the demands of far-field voice control and audio applications in conference and living room scenarios. Two suites of algorithms are available for use with XVF devices: SmartHome (based on Ambiphone) and SmartTV (based on SRTVBF). xCORE VocalFusion devices provide an integrated DSP solution which performs Acoustic Echo Cancellation (AEC), beamforming, stationary noise suppression, non-stationary noise suppression, and automatic gain control (AGC). It should be noted that, apart from the System Delay parameter (which is fundamental to the operation of AEC), the procedures listed in the document mainly relate to fine tuning of performance only. Overview This document describes the tuning guidelines and procedures for the XMOS xCORE VocalFusion (XVF) range of devices and associated voice DSP algorithms. Crosshair shows the pixel coordinates of the cursor on the monitor.XCORE VocalFusion Fine Tuning Guide IN THIS DOCUMENT. Frames of to custom sizes can shown on-screen. Guides are vertical and horizontal guide lines displayed over the screen to be used as guides. Loupe is an adjustable magnifying glass that shows the specific pixel color under the mouse. Screens overlays common screen resolutions along with the area of webpages visible to common browsers within those resolutions. Rulers measuring pixel size in both X and Y dimensions are shown over the screen and can be rotated 360 degrees. Dimensions show the pixel size (for both X and Y dimensions) of any object within a color range under the mouse. The idea behind the program is that designers can check the size of their work against real-world computer display measurements and be able to measure their work as well. 
XScope is a utility by The Iconfactory & ARTIS Software that can measure any element displayed on screen.
