AI medical interpreter for clinical trial sites
Opalite gives research sites real-time interpretation in 150+ languages and dialects for prescreening calls, study visits, dosing instructions and retention calls.
Today's challenge
What gets in the way of interpretation at trial sites today
Hokkien and Farsi candidates wait
Without a Hokkien or Iranian Farsi interpreter, the coordinator can't ask a candidate about current medicines or past liver disease.
Hold time at the dispensing visit
The coordinator waits on hold for a phone interpreter before explaining the new study kit and the returned-tablet count.
Coordinators type instead of listen
The research coordinator types interpreted source notes during the participant's account of a new symptom.
Cost of inaction
Language interpretation remains a gap at trial sites
71% lower odds
