Technical translation involves translating specialized documents about technical subjects and scientific information, such as owners' manuals. It requires a high level of understanding of the topic and relevant terminology. Technical translators must be able to convey technical meanings and linguistic features when translating documents between languages. Technical translators often specialize in a particular field and undergo training to develop both technical skills and translation abilities. They sometimes take on roles as both technical translators and technical writers, creating new meanings for words as needed. While some technical translators use computer-assisted translation or machine translation software, documents requiring creativity are less likely to be translated solely using such software.
