  • I've just listened to the final sound mix on the Kcell Investor film you recorded a voiceover for. Just to let you know that I think you sound fantastic!  I knew there was a good reason to keep your details on file. We'll be using you again!

  • Leona's voice is like silk. Add in the skills of the High Voltage Media producers and you have a perfect combination. My website is sounding very sexy and provides the perfect introduction to showcase my art.

  • High Voltage Media provided me with several fully produced liners at a reasonable cost and extremely quickly. I was impressed and shall be back for more.
    Chris Mwangale, CMJ Events, Kenya
  • The joy of working with Leona is that as soon as you hear her saying the words you've written down, it's a relief. The stress of whether a script is going to work with a voiceover just vanishes – and it happens every single time with Leona – the moment she opens her mouth. The delivery is realistic, never forced, always natural, but with an energy and excitement that cuts through and gets the message across. You can ask for retakes, but you can be pretty sure she'll nail it first time. And the production skills that High Voltage Media have gathered together means there's a one-stop shop for fantastic voices and superb production – the perfect combination.

  • Having worked with countless voiceovers over the past 15 years as a Presenter, Producer and Programmer, there are only a few names that I have used time after time, Leona gives you that edge that so many female voices can't, a sexy rasp that doesn't sound like it's put on, an attitude that makes you listen to what she's saying. Leona is diverse and so easy to produce, both during the session and afterwards, who else can make "Xylometazolene Hydrochloride" sound exciting, it's her party piece, ask her to do it when you book her.
