About Dr David
I'm David, a London-based British voiceover artist with a naturally deep, warm, and resonant vocal tone that immediately engages, reassures, and invites connection from the very first word.
My clients often describe my voice as "calm", "reassuring", "intelligent" and "trustworthy" – qualities that help your brand connect meaningfully with your audience. Whether you need narrative, commercial, TV continuity, radio imaging, medical, African or meditation voice reads, I deliver professional results with a personal touch.
And here's something a little different: Beyond the recording studio, I'm also a practicing medical doctor in the field of General Practice (GP), having trained in University College London.
My background as a keen classical chorister since my early teens has developed my acute appreciation of vocal tempo, texture, volume, intonation, saturation and control – all elements I bring to each voiceover project. I continue to nourish this passion as an active member of a London Gospel choir.
Born in the UK, and having lived in Africa and the Middle East, my exposure to different cultures and command of several languages allows me to forge connections across the globe – perfect for international brands seeking authentic communication.
So whether you're after a grounded, warm and trustworthy voice of reassurance — or a gritty, authoritative voice of gravitas — I will deliver your requirements to your complete satisfaction, with a professional yet friendly and affable touch… and a sprinkle of good humor along the way.
I work from my professional home studio in London, ensuring broadcast-quality audio and prompt turnaround times for all projects.
Your brand. My voice.
Kind words from happy clients...
I have to commend how you took the time to understand the vision of the brand.
