Quite a number of English words are derived from French, so the spelling is the same, in which case AccuLips will recognize them.

This is hardly the case with Spanish. If a word is not in the dictionary, AccuLips will fall back on the legacy system, which is a hit or a miss.

I confirm. I use acculips for french and I have just to modify a few words. In anycase, for me, it's better than the simple lipsync. 


     

Unlikely that Iclone will provide foreign languages but REPLICA STUDIOS might [ in the future ] as they are specialising in synthetic voices.  https://replicastudios.com
Latest update to Iclone provides a link in the plugins tab to access the Replica library of voices and to integrate with Acculips. Paid service of course though there is a free starter.
Also its for W10 so wondering if any one has tried installing Replica on W8.?
[Cant upgrade PC yet as waiting on new gen processors Intel 12 and Windows 11 ]  
 

So what about this?

Hey Guys, I might have a workaround. Not perfect by any means. Here are my 9convoluted steps)
1/Write your French text and record it in any recording software and export the audio file so it can be read by Iclone
2/Go to an online platform that will convert your written text to English phonetic text. I tried with toPhonetics, seems to work OK and to be free so far.
3/Load a character to IClone and launch the lip-sync interface (Animation Tab>Animation>Create Script)
4/Select AccuLips
8/In the top menu of the interface, click the" Open Audio File' Button and select your French audio clip
9/In the 'input your text here" area, paste your phonetic English text
10/Hit the "generate text" button. Ignore error message and adjust if needed, for me it did 90% of the job.
11/Hit Apply 

Not perfect, but I think it does a slightly better job than letting AccuLips figure it out by itself, and you can refine it.

Here is my quick and dirty test : https://drive.google.com/file/d/1e0HKO_9wOGXwAu3gaLXIrxxJ-Rn6IsyX/view?usp=sharing
