Their Layered Voice Analysis technology can detect various emotional states. They apply this technology to products like LVA-i for pre-employment screening and integrity assessments of employees. LVA-i balances accuracy, time, and cost compared to alternatives like polygraphs. It uses questionnaires and automated reporting to assess truthfulness and suitability of candidates.
