1. A computer system for providing real-time resources to participants in an audio conference session, the computer system comprising: a conference system for establishing an audio conference session between a plurality of computing devices connected via a communication network; and a server configured to communicate with the conference system and the plurality of computing devices via the communication network, the server comprising: a processor and a memory; a pre-processing engine stored in the memory and executed by the processor, the pre-processing engine comprising logic configured to: receive an audio stream associated with one or more of the computing devices, the audio stream comprising a speech signal; and extract the speech signal from the audio stream; a speech-to-text conversion engine stored in the memory and executed by the processor, the speech-to-text conversion engine comprising logic configured to extract words from the speech signal; a relevance engine stored in the memory and executed by the processor, the relevance engine comprising an algorithm for outputting a relevant keyword or topic being discussed in the audio conference session based on a plurality of data inputs, the plurality of data inputs comprising the extracted words from the speech-to-text conversion engine, a speaker identity with a corresponding role or category of one or more participants who spoke the extracted words, the algorithm identifying the relevant keyword or topic by calculating and updating a relevance score during the audio conference session and, if the relevance score exceeds a threshold, outputting the relevant keyword or topic, wherein the relevance score is based on a usage density associated with the one or more extracted words; and a resources engine stored in the memory and executed by the processor, the resources engine operatively coupled to the relevance engine and comprising logic configured to: receive from the relevance engine the relevant keyword or topic identified by the algorithm based on the speaker identity with the corresponding role or category; identify a plurality of resources related to the relevant keyword or topic; display in a graphical user interface and during the audio conference session, the plurality of resources to the one or more computing devices in a conference user interface associated with the audio conference session; and enable user-selection of one or more of the plurality of resources via the conference user interface.
