What Is Simultaneous Interpreting? How It Differs from Consecutive Interpreting and Live Captions

Simultaneous interpreting, consecutive interpreting, and live caption translation all bridge languages, but they serve different risks, formats, and budgets.
What is simultaneous interpreting?
An interpreter listens and speaks the translation almost at the same time. Audiences hear it through headsets. Formal events often use a soundproof booth and two interpreters who rotate.

What is consecutive interpreting?
The speaker pauses after a section and the interpreter delivers it. It needs little equipment but can nearly double the schedule, making it suitable for interviews and small meetings.
What is live caption translation?
Speech recognition and machine translation turn speech into translated on-screen text. Several languages can be delivered through a QR at much lower cost, but viewers read rather than listen.
| Method | Delivery | Resources | Several languages | Cost |
|---|---|---|---|---|
| Simultaneous | Spoken via headset | Interpreter teams and equipment | Team per language | Quoted |
| Consecutive | Spoken in turns | Interpreter | No | Hourly |
| Live captions | Screen or phone text | Computer and internet | Yes | Usage based |
Which should you use?
- Use trained interpreters for legal, diplomatic, and high-risk content.
- Use consecutive interpreting for a small bilingual discussion.
- Use live captions for multilingual talks, streams, and tours where accessibility and cost matter.
