31. An apparatus for calculating an interaction churn score in an organization with which the customer has an interaction, the apparatus comprising: a voice recording device for capturing the interaction; a category definition component for defining a plurality of categories, each category characterized by an at least one parameter of a voiced expression; an extraction engine for extracting information from the interaction; a category score determination component for determining at least one category-interaction indication associating the interaction with at least one churning category out of a total number of categories; an interaction churn score determination component for determining an interaction churn score related to the interaction, wherein the interaction churn score comprises a term directly related to the number of churning categories the interaction is associated with and inversely related to the total number of churning categories based on a formula as: 
 A *(maximal score for a churning category)+ B *((the number of churning categories into which the interaction is categorized)/(the number of churning categories)*100), wherein A and B are coefficients that satisfy a condition of A+B=1; a transactional churn score determination component for determining a transaction churn score for the customer, based on additional data related to the customer or to the organization; a combined churn score determination component for combining the interaction churn score and the transaction churn score into a combined churn score; a retention offer engine for making a retention offer to the customer; and a capturing or logging component for capturing the interaction; and wherein the cited components comprise processing apparatus configured to perform the corresponding tasks cited above and wherein the cited engines comprise processing apparatus configured to perform the corresponding tasks cited above.
