A New Way to Communicate

Multi-lingual Multi-language staffing with live interpreters is costly and inefficient. Data reveals that the use of an interpreter is unpredictable from day-to-day. This makes staffing decisions of multi-lingual personnel difficult, impractical, and inefficient. This is further complicated by the fact that we live in an increasingly multilingual society. Risk Mitigation Instant interpretation is provided by […]
