Customer Wins

Leading North American, European, and Asia-Pacific telecommunications companies, travel organizations, financial institutions, healthcare providers and others continue to turn to Nuance for phone self-service solutions that improve the customer experience and reduce costs.

During the first quarter, industry leaders, including Alaska Airlines, Austar, Caremark, SunTrust Bank, Inc., TELUS, West Corporation, and others made their initial investments in Nuance or expanded the capacity of their existing Nuance voice automation solutions.
