Machine Translation

Memsource Translate

Memsource Translate uses AI to automatically select the optimal MT engine for your translation jobs, based on each job's domain and language pair. It includes Machine Translation Quality Estimation (MTQE) which supports many language pairs.

  • Memsource Translate is provided in all accounts and is after March 12, 2019, the default machine translation engine.

  • Memsource Translate characters can be used by all MT engines supported by Memsource Translate.

  • Multiple instances of Memsource Translate can not be created.

  • Free characters are included in each edition (Ultimate: 2M, Team and Academic: 500k, Team Start: 250k, Personal: 50k). These characters are for testing purposes and specific to the purchased edition; upgrades do not include more characters.

  • Once purchased, Memsource Translate (and MTQE) characters do not expire. They can be later used after renewing/reviving a subscription.

MT Glossaries

MT Glossaries ensures terminology is handled correctly by MT engines. They function in a similar manner to term bases but are used by machine translation engines instead of linguists. Terms added to a glossary are applied by the machine translation engine before being seen by the linguist. This means that the terms provided are consistently and always substituted and typically include product names, ambiguous or borrowed words.

Glossaries are not supported by all machine translation engines and are only available through Memsource Translate. If supported, this will be indicated in the machine translation profile along with the supported glossary languages. Additions to glossaries can take up to 15 minutes to be propagated to MT engines.
