Short definition
Telephone Conference Interpreting refers to interpreting within a telephone conference – participants and the interpreter are connected exclusively by phone.
Detailed explanation
TCI is one of the oldest forms of remote interpreting and requires no video: communication runs entirely through the phone line. Typical use cases include brief business coordination calls, conversations with authorities or service providers, or situations requiring fast, unprepared language mediation – for example, in healthcare or social services.
The limitations resemble those of other audio-based formats: without video, visual context is missing, and the often limited audio quality of classic telephony makes the work even harder. TCI therefore suits short, clearly structured dialogues rather than complex or lengthy conferences. With improved audio transmission and video options, usage is increasingly shifting toward video- and platform-based formats (VRI/RSI). The terminology overlaps with ACI and ARI.
Relevance in this subject area
TCI marks the simplest, quickly available access point to remote interpreting – useful as a stopgap, but clearly limited by the lack of video and audio quality.
Practical example
An authority needs ad hoc language mediation. Through a telephone interpreting service, an interpreter is connected into the call within minutes – consecutively and without video.
