Sounds like the videos need closed captions. Not a particularly difficult task to add them. It can be frustrating to go back and do this with older content, but captions make the videos accessible to a lot more people. Automated captioning software is also very high quality these days. There’s really no reason not to do it these days.

There are also commercial services that use a combination of automation and people fluent in the languages at play that are both very inexpensive and rather quick in terms of turnaround. We've used them for internationalizing training videos and the like as well as subtitling movies — we have to use essentially "airline" edits of movies, and sometimes they don't have the languages we need (e.g. French for Canadian customers).
