Cathleen’s academic and practical grounding in voice and how to apply it is second to none

Michael Corbidge, Associate Voice Practitioner, RSC- Developer

I have over ten years expertise working on Voice for Performers and Voice for Business and Professionals.  

During the Covid 19 pandemic, sessions are available via Zoom, Skype or any other online platform we can both access.  I am based in London (GMT) but sessions are possible across all time zones.

Voice for Performers

The work we did together has not only given me a better voice – with more truth, range and resonance – it has made me a better actor

Louise Brealey, Actor- Developer

Your voice is one of your greatest assets as a performer.

Whatever your area of performance – actor, narrator, storyteller, comedian, speaker – I can work with you to make your voice and text skills the best they can possibly be.

As a voice coach with an acting background myself, I’m passionate about helping people to develop the best possible version of their voice, finding range, flexibility and freedom without ever losing their unique, idiosyncratic qualities.

My work is person-centred, non-judgemental, supportive and enabling

There are many areas I can help with

Vocal Technique

Producing your voice requires the involvement an extraordinary number of muscles and processes within the body: breath, thought, alignment, ribs, diaphragm, throat, tongue, spine to name but a few. This means that there are many areas we can look at to improve your technique, or to solve any issues you feel may be holding your voice back.

Detailed Work On Discovering Character Through Text And Language

If you are preparing to play a part with complex language, classical or modern, there are many practical and fun ways in which we can break down the text, find the acting possibilities within it, and equip you to go into rehearsal confident and ready to play.

Dialect Coaching

Some people are lucky enough to have a fabulous ear for accents, but if not, then fortunately there is a systematic process we can apply to any accent, working practically on areas such vowels, consonants and rhythm/intonation and marrying these with aspects of text and character.

Audition Speeches

Whether you are preparing for drama school or professional auditions, we can work together on a specific speech, classical or modern, to really mine all the possibilities of the text and leave you feeling confident and ready.

Audio narration & voiceover

Whether your area is narration, animation, gaming or drama, the world of audio demands great vocal creativity, flexibility and clarity. I can give you techniques for developing character voices whilst protecting your vocal health and stamina, help you prepare accents, or offer ways of exploring texts to bring pace, rhythm and variety to your work.

Voice Warm Ups

if you would like to learn how to warm up your voice, or would like a reminder of old, half-forgotten warm up techniques from drama school, then we can work through a safe and effective sequence which can also be recorded for your future use.

Voice for Professionals and Business

Whatever your job, much of your effectiveness and success depends on how you use your voice to communicate with others. It is easy to feel that your voice is somehow letting you down at work: perhaps you find your voice wavering when asked to present at meetings, or you feel that you speak in a monotone and want to find more variety and colour. Perhaps you find your voice getting strained and tired by the end of the day, especially nowadays, with endless online meetings. Or perhaps you want to refresh the way in which you present material at work, finding new ways to use words and language in a way that makes them “sticky” for your audience.

Over the past ten years, I have worked with lawyers, doctors, teachers, bankers, police officers, fashion buyers, politicians, film and theatre directors, media professionals and many many others, using my voice and text skills to help them to achieve a healthy, flexible and expressive voice and to use language more persuasively and effectively. I can work with you to identify the precise source of any issues and give you practical exercises, tips and strategies for development.

Areas I can work on include


Practical work on developing the range, resonance and clarity of the voice

Public speaking

Dealing with nerves, being loud enough for the space, using pitch, pace and pause appropriately

Presentation skills

Making language persuasive and “sticky” by drawing on techniques from the world of rhetoric and dramatic writing

Vocal stamina

Practical strategies to prevent the voice becoming tired during demanding activities such as teaching or lecturing

Cathleen’s skills base is vast….she has a passion for sound-making, the spoken word and how stories are told. She knows her way around technically and anatomically so is always to help actors find range and flexibility as well as pinpointing anything that prevents them using their voice to maximum effect. Coupled with her understanding of language she is able to open up the myriad of possibilities within text for actors. Her academic and practical grounding in voice and how to apply it is second to none, so coupled with her strong clear communication skills she’s an expert workshop leader, teacher and facilitator. She is a thoroughly likable person with a sunny disposition who cares deeply for the work. She is conscientious about all she does, working with initiative and, most importantly, she is well liked by all who come in contact with her for her clarity, passion and skill.

Michael Corbidge

Royal Shakespeare Company

I am amazed at how much I have learnt…I’ve been impressed by how many of the issues I had with my voice she picked up on, just by listening to me, and she’s also identified some other areas for me to work on that I hadn’t previously been aware of. Cathleen has taken me through a series of exercises, each time building on the work of the previous lessons and then exploring a new area. She gives very clear explanations of why each exercise is important and enough detailed instruction so I feel confident about practising by myself. She has followed up the sessions with really useful notes to remind me what to do. Above all, the lessons have been very relaxing and enjoyable. Cathleen has been a pleasure to work with, a thoroughly dedicated coach and I would highly recommend her as a voice coach – the whole experience has been one of the best value bits of training I’ve ever had and I shall certainly go to her in the future, when I feel I need to do some more work in this area.

Professional Storyteller

You’ve made a hugely vital contribution to this production. Thank you!

Anthony Green

Director, “Othello”, London 2013

Your mastery of voice work helped me receive fantastic reviews for my HERO in Much Ado. You are incredible.

Amara Karan

Actor, Hero in "Much Ado About Nothing" RSC 2012

I wouldn’t have had the skill or the confidence to have played three roles in The Gate’s Trojan Women without working with Cathleen. The work we did together has not just given me a much better voice – with more truth, range and resonance – it has made me a better actor.

Louise Brealey


I learnt more with Cathleen in a few sessions then I did on my 3 year acting course. I didn’t really know anything about voice and was very unsure in my own ability. I was quite nervous for my sessions at first but Cathleen made me feel extremely comfortable and confident. I have learnt skills and techniques that I can take with me throughout my whole career and even after a short time I have a much greater understanding of my voice and body. I always leave the sessions feeling like I’ve worked really hard but at the same time had lots of fun – there’s a lot of laughter! I can’t recommend Cathleen enough, I know I’m extremely lucky to have found such a great teacher.
