The Paper Describes Possibilities, Which Are Provided By Open APIs, And How To Use Them For Creating Unified Interfaces Using The Example Of Our Bot Based On Google API. In Last Decade AI Technologies Became Widespread And Easy To Implement And Use. One Of The Most Perspective Technology In The AI Field Is Speech Recognition As Part Of Natural Language Processing. New Speech Recognition Technologies And Methods Will Become A Central Part Of Future Life Because They Save A Lot Of Communication Time, Replacing Common Texting With Voice/audio. In Addition, This Paper Explores The Advantages And Disadvantages Of Well-known Chatbots. The Method Of Their Improvement Is Built. The Algorithms Of Rabin-Karp And Knut-Pratt Are Used. The Time Complexity Of Proposed Algorithm Is Compared With Existed One.
