In most countries, the government is the largest buyer of interpreting services because, as the below graph illustrates, the public sector is the dominant market in most countries.
The interpreting market is a diverse and complex sector within the language industry. There are different modes — consecutive, simultaneous, and whispered interpreting — and different modalities, i.e. onsite, over-the-phone (OPI), and video-remote interpreting (VRI). There are different types of interpreting, like medical, legal, community, and conference interpreting and all of them come with their own requirements.
