# #5 Use & Utilization
You can select and use vocabulary (TB), speakers, and translation memories (TM) for each project that you have already created.
When you activate a segment in the editor, you can check the matched glossary and translation memory (TM).
Voice cast can only be used for video dubbing projects, you can use it by selecting a provided voice template.
## Select a glossary and translation memory (TM)
Select the glossary and translation memory (TM) to use when creating the project.
* For transcription and proofreading projects, we do not set up a translation memory (TM), so you can only select a glossary.
* If you need to change the glossary, replace it with a different one on the Project management page.
## Glossary, Translation Memory (TM) matches
Check the terminology (TB) of the matched glossary and ensure it matches the words in the sentence.
* If the start and end sentences of the language pair matches, it is displayed in green
* Missing or inconsistencies in translated sentences are displayed in gray
Terminology (TB) matches
If the registered speaker is correctly applied within the sentence, the speaker's word appears in the area below the subtitle.
In addition, you can identify Translation Memory (TM) sentences with a high similarity rate and use them as a substitute for MT.
