Mechanisms, in a natural language processing (NLP) system are provided. The NLP system receives performance data for a performance to be provided by a human performer. The performance data comprises an objective to be achieved by the performance. The NLP system monitors channels of communication to identify natural language statements exchanged over the channels directed to the performance while the performance is being presented. The NLP system extracts feedback information from the natural language statements and generates aggregate feedback information. The NLP system evaluates an alignment of the aggregate feedback information with the objective and outputs a guidance output based on results of the evaluation. The guidance output guides the performer to modify presentation of the performance to more likely achieve the at least one objective based on the aggregate feedback information.
