In addition, mergers and acquisitions create new names or new ticker symbols for listed companies. This means that all these changes must be tracked and applied to the production system recognition grammars. Nuance has been supporting mission critical brokerage systems since July 1996, and has developed the internal infrastructure required to provide consistently high quality recognition coverage and performance for brokerage applications. As a second input, Nuance transcribers monitor the performance of deployed systems. When recognition problems are detected, the data is analyzed and new pronunciations and phrasings of company names are incorporated.
Nuance tests each new grammar before certifying it for use in a deployed system.
Testing includes batch-recognition of thousands of utterances to benchmark performance in terms of both speed and accuracy. Only if the grammar performs within expected parameters is it certified for use in a production environment. Once a grammar is certified, it is made available to customers via a password protected secure FTP site. Customers can also download the grammar via the internet. Implementation Services Nuance offers experienced implementation services as part of the BrokerageSuite package to ensure robust operation of systems.
