The Listen & Learn™ family of features enable speech recognition systems to automatically detect and adapt to the unique speech characteristics of a carrier's or enterprise's broad customer base as well as individual callers. With Listen & Learn, carriers and enterprises can improve accuracy as well as provide each caller with a tailored experience.

• Auto-tuning
  With Auto-tuning, speech recognition systems can be automatically tuned to account for characteristics common to a specific carrier or enterprise's caller population. For instance, a carrier serving subscribers in the southern United States can use Auto-tuning to automatically adapt its voice-driven customer care system to account for the unique southern accent common among its subscribers. Auto-tuning also enables speech recognition systems to automatically detect phrases and words that callers often use when interacting with the system, improving the system's ability to accurately recognize these frequently spoken expressions. In many cases, Auto-tuning can reduce error rates by as much as 60 percent resulting in faster customer transactions and improved quality of service. Moreover, because Auto-tuning helps automate the tuning process, development effort, time and costs can be reduced, freeing valuable IT resources to focus on other projects.
• Personalization Kit™
  Personalization Kit provides patent-pending technology that analyzes voice characteristics and environmental conditions of an individual call in real-time. Personalization Kit can determine whether the user is a man or woman, identify the type of phone (wireless or landline) and assess background noise levels present during a call. Enterprises and carriers can use this information to create user interfaces tailored to each caller, making services easier to use. For instance, a voice recognition system may have difficulty hearing a very soft-spoken person calling from a noisy, public location. Using the Personalization Kit, the system can prompt the caller to "please speak a little louder" so that the individual may be heard. Increased revenue-generating opportunities are also possible by offering callers real-time, targeted marketing information on products and services based on demographic characteristics, such as gender.
• Dynamic Language Detection™
  Dynamic Language Detection allows voice applications to automatically detect in real-time the language the caller is speaking. The caller simply begins speaking in his/her preferred language and the system understands and can interact with the caller accordingly. The system can also recognize with high accuracy if the caller mixes languages or speaks in a heavy accent periodically throughout the call. This is particularly beneficial when offering voice-driven services to multi-lingual markets such as English-French speaking Canada and many English-Spanish speaking markets throughout the United States.
