Virtins Technology
Sound recognition is one of the main application areas of artificial intelligence. Various sound recognition techniques exist and can be used for recognizing speeches, music, environmental sounds, animal sounds, air-borne or structure-borne machine sounds, etc. These techniques contain in common signal pre-processing, feature extraction and feature matching / classification algorithms from a general perspective. However, they differ in implementation in different applications. For example, there are a few good automatic speech recognition software products and APIs, however, they just cannot be used directly in animal sound classifications.

VOIP Echo -
GL Communications Inc.
*The Voice Band Analyzer (VBA) is an analysis tool for monitoring the quality of voice band traffic (including hybrid echo) over VoIP, TDM and wireless networks*VBA works in conjunction with GL's TDM, Packet, and Wireless non-intrusive capture products, such as T1 and E1 Call Capture and Analysis, VoIP PacketScan&trade, and GSM, CDMA, and 3G Call Capture Products. VBA instantly detects voice file captures and with appropriately installed analysis modules, monitors speech levels, noise levels, and hybrid echo. Other analysis modules such as ITU-T P.561, P.562, P.563, fax and modem analysis, and many others can be hosted as plug-ins.*The VBA application can also operate on pre-captured files. It supports A-Law, µ-Law, 16-bit PCM (Intel), 16-bit PCM (Motorola) and MS Wave file formats.*Required software PKV100 and VBA032 at each probe location and PKV170 PacketScanWEB - Network Surveillance Software*Required hardware - 1U rack PC with sufficient hard disk for capturing over 10,000 calls (80 GB HD) for each VBA colocated with a probe*Additional hardware - PC for PKV100 PacketScan™ Software
