Synpatic is a team of professional Mathematicians and Software Developers, working both in Chile and Belarus, enriched with business expertize of team members in Commerce and Management. We develop Audio Analysis technology for automatic prediction of Call Center quality metrics based on emotions detection of both client and agent during phone call. In other words, our software measures the empathy level of Call Center agent, as well as satisfaction level of Call Center's customer. We propose our clients integration of this technology and analysis of results of its work. Currently Chile is the main geographical market of Synpatic. We use features extraction algorithms (Digital Signal Processing) in combination with Machine Learning engines, to build first classifiers of emotions, and then convert this into corresponding Call Center metrics.
