In an increasingly global and virtual world, language access isn’t just a necessity—it’s a priority. Whether in healthcare, legal, education, or customer service, organizations need real-time communication solutions for individuals who speak different languages. Enter remote interpreting services—a suite of flexible, efficient options designed to deliver instant, accurate language support.
Two of the most widely used methods are Over-the-Phone Interpreting (OPI) and Video Remote Interpreting (VRI). Both are forms of virtual interpreting, and while they serve similar purposes, they offer different experiences, capabilities, and use cases.
Over the Phone Interpretation Services (OPI) can sometimes be called over the phone translation, phone translation service, telephone interpretation services, telephone interpretation.
This blog explores the differences between VRI vs. OPI, what each service entails, and how to determine which on-demand interpreting solution is best for your organization.
Virtual interpreting refers to any real-time language interpretation conducted remotely, rather than through on-site interpreting. This includes both audio-based and video-based services, typically delivered through secure platforms or devices.
Virtual interpreting offers:
Instant access to certified interpreters
24/7 availability
Flexible delivery across industries
Scalable, cost-effective solutions
The most common types of virtual interpreter services are:
Over-the-Phone Interpreting (OPI)
Video Remote Interpreting (VRI)
OPI is a phone interpretation service that connects an interpreter and two or more parties via telephone call. It is audio-only, meaning no visual interaction is involved.
Instant access to interpreters via phone or VoIP
Ideal for emergency services, customer support, and brief interactions
Available in hundreds of languages
Cost-effective and widely accessible
Call centers and customer service lines
Government hotlines or immigration offices
Insurance and financial services
Basic medical consultations
💡 Example: A pharmacy chain uses OPI to help customers understand prescriptions in their native language, offering fast, convenient assistance.
Video Remote Interpreting (VRI) is a real-time video interpretation service that enables interpreters to see and hear the individuals they are interpreting for. VRI is particularly useful when visual cues, facial expressions, or sign language interpretation are essential to the conversation.

You need quick language support via audio
The conversation is brief and doesn’t require visual interaction
You are managing high call volumes (e.g., call centers, public service hotlines)
Facial expressions or gestures are important
You’re working with the deaf or hard-of-hearing community
You need interpretation for telehealth or legal conversations with nuance
You're delivering sensitive information where visual empathy matters
While VRI and OPI are two of the most common remote interpreting services, your business might also benefit from complementary solutions, such as:
Virtual Interpreting via Client Platforms: Some companies prefer to connect interpreters to their own video tools like Zoom, Webex, or Teams.
On-site Interpretation vs. Remote Interpreting: In certain cases, in-person interpreters are still the most effective solution—especially for high-stakes or lengthy events.
On-demand video interpreting for customer service kiosks, mobile apps, or hybrid workplaces.
