SP13 HOTLINE - Hotline

Every customer sometimes needs help with new and unusual products. Therefore, hotline service is very important for every company. We need a single phone number where the customer can always find a friendly voice ready to help with anything. On the other hand, many people are needed to serve as hotline operators, and human resources are always very expensive. Moreover, it is not easy to pretend "friendly voice" at 4am and explain to a drunken man that you are really unable to give him the number to House of Parliament. It was also found that some of the questions repeat very often and it is very annoying to answer them again and again. ACM is a modern company, wanting to solve its hotline problem. They want to decrease the number of human operators by creating a complex software system that would be able to answer most common questions. The customer's voice is analysed by a special Voice Recognition Module (VRM) and converted to a plain text. The text is then taken by an Artificial Automatic Adaptive Answering Algorithm (AAAAA). The most common questions are recognised and answered automatically. The replies are then converted to a sound by Text-to-Speech Module (TTS). You are to write the AAAAA module. Because your algorithm should be adaptive, it has no explicit knowledge base. But it must be able to listen to sentences in English and remember the mentioned facts. Whenever the question is asked about such a fact, the system has to answer it properly. The VRM and TTS modules are already implemented, so the input and output of AAAAA will be in the text form.
