OPI, or over-the-phone interpretation, is a service that connects a caller with a live remote interpreter via telephone in seconds. A three-way call is established between the limited-English speaker, the English speaker, and the interpreter, who translates consecutively. OPI is the fastest and most accessible form of language access, available around the clock in hundreds of languages. Translation Ratings lists 15 OPI providers operating in the United States.
The process is straightforward: (1) The organization or individual dials the OPI provider's access number. (2) The caller enters their account ID and selects the target language. (3) Within seconds, a live interpreter joins the call. (4) The interpreter translates back and forth between both parties in consecutive mode. (5) When the call ends, the session is logged for billing and quality purposes. No app, equipment, or prior scheduling is required.
Leading OPI providers in the United States offer interpretation in 200+ languages and dialects, including rare indigenous languages and regional dialects.

Yes, and it is one of the most common use cases. OPI is used extensively in hospitals, clinics, telehealth visits, and pharmacy consultations. HIPAA-compliant OPI providers encrypt call data and offer BAAs for healthcare clients. However, for complex or lengthy medical conversations, especially those involving serious diagnoses or end-of-life care, on-site or VRI interpretation may be more appropriate.
OPI is generally not accepted as a substitute for in-person certified court interpretation in formal legal proceedings such as criminal trials or depositions in most US jurisdictions. However, it is widely used in intake interviews, attorney-client consultations, immigration case preparation, and police interviews. Check local court rules before relying on OPI for any formal legal procedure.

OPI is typically billed per minute. Rates range from $0.90 to $3.00 per minute depending on the language, provider, and contract volume. Spanish and major European languages are at the lower end; rare languages are at the higher end. Many providers offer flat monthly rates for high-volume users such as hospitals and government agencies. Translation Ratings shows pricing structures for all 15 listed OPI providers.
Most OPI providers charge a minimum of 1–2 minutes per call to cover connection setup. Some providers also charge a per-call connection fee. For organizations that use OPI frequently, negotiated enterprise contracts with prepaid minute packages significantly reduce per-minute costs. Always ask about minimum charges and whether unused minutes roll over.
Completely free OPI for general use is rare. However, some government programs and federally funded organizations are required to provide language access at no cost to patients or clients, the organization absorbs the OPI cost. Additionally, some healthcare plans cover interpretation costs. For individuals seeking free interpretation, checking with local legal aid, community health centers, or government social services is a good starting point.
Reputable OPI providers hire interpreters who are fluent in both languages, trained in interpreting ethics and technique, and often hold industry certifications such as CCHI (healthcare) or have passed proprietary qualification tests. Interpreters are typically monitored for quality on an ongoing basis. Translation Ratings highlights OPI providers that disclose their interpreter qualification standards.
