On-Site Interpreting (OSI)

On-Site Interpreting (OSI), also referred to as in-person interpreting or face-to-face interpreting, entails a professional interpreter being physically present at a specific location to aid communication between individuals speaking different languages. Unlike remote interpreting methods, onsite interpreters are physically present in the same room or space as the parties involved in the interaction.

In certain situations (e.g. court hearings, parent-teacher meetings, hospital visits, etc.), having a professional interpreter physically present is preferred. PGLS is dedicated to sourcing the right interpreter, in the right location, at the right time. We have a national presence that allows us to leverage our relationships and network of interpreters to provide OSI across the US. We are confident we can meet your OSI needs.

Benefits of On-Site Interpreting

In-person interpreters can directly observe facial expressions, body language, and other non-verbal cues, allowing them to better understand and accurately convey the intended message between parties. They can also better observe and respond to cultural nuances, social dynamics, and sensory cues that may impact communication, ensuring that all parties feel respected and understood.

Flexibility & Adaptability

Onsite interpreters can adapt their interpreting style and approach based on the context, participants, and dynamics of the interaction. They can switch between consecutive and simultaneous interpretation modes as needed, or adjust their position, tone, and mannerisms to accommodate changing needs or preferences during the interaction.


In-person interpreting allows for more natural and authentic communication. Being physically present in the same room as the participants allows onsite interpreters to establish a personal connection, build trust, and foster rapport between parties.


Onsite interpreting does not rely on internet connectivity or technical infrastructure, making it more reliable in situations where internet access may be limited or unreliable.
