Abstract
A system may include machine learning models. A system may receive audio information representing an utterance of a conversation session. A system may divide the audio information into a plurality of audio portions. A system may evaluate a first audio portion using a tone-based sentiment analysis model to generate sentiment probabilities. A system may determine a first positive sentiment probability exceeds a threshold. A system may generate a textual representation of the first audio portion. A system may evaluate the textual representation using a topic identification model to generate a topic result indicating a topic. A system may evaluate a second audio portion using the tone-based sentiment analysis model to generate second sentiment probabilities. A system may determine a second positive sentiment probability does not exceed the threshold.
