How to find other people to improve English speaking ability?

There should be some speech or communication classes available in a local college. Right now all the classes are conducted virtually so they should have Zoom meetings where you can practice speaking.

There are many sites that allow you to find English language speaking partners, though not necessarily groups.

• The FluentU blog post Want to Practice Speaking English with a Native Speaker? Go Online! (published in March 2016 and updated in June 2020) discusses several options, some of which are free (e.g. Conversation Exchange, Go Speaky, Busuu and Lingoglobe).
• Find your English speaking partner online on IELTSGame.com, which recommends italki.
• Lingvonet allow you to find a speaking partner by country; you can also specify whether you want to use Skype or not.
• The article How to Find Conversation Partners: The Best Language Exchange Sites on Mosalingua.com (originally published in 2013) discusses the pros and cons of various sites, including italki and Conversation Exchange.
