English is now the working language of global business, but spoken English is still judged socially, professionally, and technologically.
Your voice affects how you are perceived:
Clear or unclear?
Credible or uncertain?
Authoritative or hesitant?
Today, many of those judgements happen through screens, recordings, transcription systems, and international meetings where small communication problems become amplified.
Vox London is a Global English and professional communication consultancy, founded by British English teacher, speech specialist and corporate communications professional, Mary Dee.
Mary works with international professionals and organisations on spoken English, speech clarity and communication - from executive meetings and presentations to the increasingly AI-mediated workplace. She is the author of Global English, Clearly.
This is not about imitation or accent performance. It is about sounding clear, credible, and authoritative anywhere.
British precision. Global Clarity.

She works with leaders and professionals who use English at a high level and want to sound clear, credible and authoritative.
At Vox London she focuses on how voice is perceived in high-stakes environments, including meetings, presentations, media contexts, and global leadership roles, where clarity, trust, and authority really matter. (Why not see how clear you are in English using her free diagnostic tool, Clarity?)
