The other types of interpretation aside from  Simultaneous Interpretation are:
CONSECUTIVE INTERPRETATION which is carried out after the speaker takes a pause at every interval of about 2 to 5 minutes and the interpreter is left to repeat what was said in the target language. This type of interpreters are most often employed in small meeting and court hearing.
ESCORT INTERPRETATION: Also known as Travel interpretation, they mainly accompany business travelers on their trips and also serves the bridge between the two cultures.
WHISPER INTERPRETATION: This type of interpretation is very much like that of the Simultaneous Interpretation but in this case, the interpreter is not in a booth, rather, he or she sits side-by side to the person for whom he or she interprets.  This type interpreter always accompanies the president of a country on every international trip where a different language is spoken.
TELEPHONE INTERPRETATION: This kind of service, like the name implies, happens over the telephone where both parties schedules a time to resolve an issue that arise from a form of language barrier. This services is mostly employed by customer service sections of many organizations.
