I want to write about a website that we can talk at the same time with others by using voice or video chat because it is optional to use one of them, and I am not sure what can I use by or with in the sentence. for example.

"It is the best website to find a lot of groups for practicing English speaking skills by / with using both voice or video chat."

  • I think the title was correct "by/with using both."

You might also be looking for the conjunction "and/or", which means either one, or the other, or both:

We can practice by using voice and/or video chat.
