What is most valuable?
* One of the most accurate voice recognition technologies, including adaptability both for dialect and lexicon.
* The lexicons are well developed by the industry, especially travel and financial services.
* Implementation had few issues and technical product support was strong.
What needs improvement?
* The technology is solid with known lexicons and expected responses, but still has room for improvement identifying responses out of context.
What other advice do I have?
* When migrating client base to voice response, make sure there is adequate communication before release, and offer touch tone alternatives.
