CafeTran

I have been using Mac online dictation with CafeTran, and when a segment is really long (e.g., 2300 characters), it starts lagging badly after I've typed about 1200-1400 characters in the target segment. Not a usual segment length, but I often have such long segments from Excel (one cell - one segment).

Can the performance be improved?

Thank you, that is something for me to learn from scratch :) I'll need to experiment with it in my free time.

(Yes, mqxliff.)

Sticking with two TextEdit windows side by side this time.

You could also experiment with the external Word table. Here you can limit the segment length macro-wise*), if this is linguistically possible. 

Add a unique character at the position of every split.

Translate the shorter segments.

Rejoin the segments at the inserted unique character.

Create a memory from the table.

Use this memory in CafeTran Espresso for the external project (mqxliff, wasn't it?).

The macro should be useable in MS Word too, once adapted.

Ah, it is an external project...

Yes, binding an external editor may work best. And of course removing any non-essential resource.

I cannot do it with an external project. 

I guess I'll just copy the segment contents to a text editor and work with two windows side by side. Anyway, I do not need any TMs or TBs for this content.

Or alternatively, I could try binding an external editor.

Maybe try with different segmentation settings?

With typing, lagging starts some time later.
