It is possible to mark out the following problems of translation:

1. A source language text is not final and is re-written when translation is done.

2. A text is written illegibly.

3. A text contains orthographic errors.

4. A text is a fragment only.

5. A text is poorly made.

6. Absent references in a text (for example, a translator must translate titles or signatures to the absent pictures).

There can be defined several essential problems related to the language:

1. Dialectal words and neologisms.

2. The unexplained acronyms and abbreviations.

3. Incomprehensible jargon or slang.

4. Extremely specific nationally biased lexicon.

Consecutive translation is one of the types of interpretation or verbal translation, when a talker pauses in speech from time to time, as this interruption are necessary for a translator to interpret what was said. These pauses, as a rule, are short, as a professional translator usually formulates translation during sounding of speech already and when pausing pronounces it. Consecutive translation requires the special and serious teaching and training.

Verbal translation can be executed consistently after pronouncing a statement by the speaker or synchronously and simultaneously with the speech of a speaker.

The translation of conversation or bilateral translation is the special type of verbal translation, when a translator alternately uses each of the languages as a language of translation. There are the also mixed types of translation such as verbal translation of a written text (or «unseen translation») and written translation of verbal speech.

Verbal consecutive translation is usually used for conducting measures with relatively bit of participants. The given type of translation is very effective at «the mobile character» of communication with a plenty of movements, for example, during work on industrial objects, negotiations with subsequent excursions etc.

It is acceptable to define several essential measures that are accomplished by using the consecutive translation:

1. Business negotiations.

2. Telephone negotiations.

3. Seminars, meetings, round tables with a bit of participants.

4. Briefings and press-conferences.

5. Presentations and exhibitions.

6. Festive measures.

7. Conducting excursions for foreign guests.

8. Mounting and tooling of equipment with participation of foreign specialist.

In comparison with the synchronous translation several advantages of the consecutive translation can be outlined:

1. The additional technical equipment is not required, that promotes mobility of a measure.

2. It can be carried out afoot, for example, during work on industrial objects, negotiations on presentations, when accompanying delegations.

3. Additional time which can be useful for consideration of an issue appears to be used by participants (for example, on business negotiations).

4. It is enough to attract one skilled translator, unlike simultaneous translation when at least, two simultaneous interpreters are required to attract.

In comparison with the synchronous translation several disadvantages of the consecutive translation can be outlined as well:

1. Conducting a measure takes more time because of pauses on consecutive translation.

2. Possibility of translation into one foreign language, as a rule.

3. The limited number of participants in an action.

Simultaneous translation is one of the most difficult types of verbal translation executable with the use of the special equipment intended for accomplishing it. Owing to the used equipment, a translator carries out translation simultaneously with talker’s speech, that’s why there is no need pausing to give more time for accomplishing translation to a translator.

The special equipment is the simultaneous translation system that usually is a stationary or demountable booth, where setting of simultaneous translation including two pairs of headphones and microphone for translators is placed as well as set of headphones or portable receivers on the number of participants who needs translation. During translation, a simultaneous interpreter is in the sound-proof and isolated booth in headphones, so as not let his own voice suppress voice of a speaker. With the apparatus of strengthening, translation is given for the listeners in their headphones. With the use of technologies of the simultaneous translation the measures with participation of large number of people are organized as well as conferences, seminars, presentations etc. conducted in conference halls or audiences.
