Applied Voice & Speech Technologies, Inc. (AVST) is a privately held software company headquartered in Orange County, California. It specializes in developing business communications solutions focusing on medium to large enterprise, government, higher education, healthcare, and hospitality markets. The company is known for its primary product, a speech-enabled unified communications platform, called CX-E (formerly CallXpress). CX-E applications include call processing, voicemail, unified messaging, personal assistant, mobile client, automated attendant, uniform call distribution (UCD), fax, speech, notification and other business process capabilities. AVST is one of the few switch independent developers of unified messaging/unified communications solutions. The companys history goes back to the 1980s when the first versions of Intel server-based voice messaging and call processing systems were released. The CallXpress product originated from Applied Voice Technology (AVT, NASDAQ:AVTC) which later became Captaris, Inc. In 2003, Sound Advantage purchased the CallXpress Voicemail and Unified Messaging solution from Captaris and this merger of technologies became a new entity called Applied Voice & Speech Technologies, Inc. (AVST). The acquisition included the retention of key products and technology as well as the entire product engineering, support and sales teams. AVST was established in September 2003 by the merger of Sound Advantage (established in 1997) and the AVT division (established in 1982) of Captaris, Inc. (NASDAQ: CAPA).
