Are you an adult who has a lisp or speech sound errors?

Is your speech interfering with your communication impact?

Has someone commented that you sound childish or immature?

Do you feel that your speech differences influence your work or social life?

As speech pathologists, we follow the principles of motor learning to assess and work with adults who have difficulties with particular speech sounds.

Common speech sound difficulties may include:


s, z, ch sh, r, & l.


Do not worry if your target sound is not listed, our team are qualified to work on all sounds within the English language. 


Your lisp and speech sound assessment is the first crucial step in addressing your concerns. Our Speech Pathologists will look at your speech sounds, as well as voice and social communication impacts or concerns. So whether you are based in Melbourne, or need online sessions, our services are for you. 


We know that it may not be realistic to take time out of your workday to visit us on Collins St, so we also conveniently provide sessions online to ensure that you can undertake sessions at a suitable time. There is no difference between face to face and online services, so you can be assured that you will receive a quality service with either pathway.

Our team are still offering appointments throughout the current COVID- 19 Pandemic.

We moved to our virtual clinic on Monday the 16th of March, 2020, until further notice.

As such, our team will deliver your appointment online.

Each of us, yourself included, are crossing paths with vulnerable citizens of our communities. At Voice Science, we do not want to fail to react & respond to this critical phase.

Our virtual clinic has been running for 6 years alongside our Collins St site. We have served every continent other than Antartica & Africa! The gear and tech needs no dress rehearsal, all we need is your ongoing trust & faith in our high quality service as always. We will however reach out to you personally, with a video tutorial to orientate you fully for your coming sessions.

My team is valuable and I’ve always wanted a safe and beautiful environment at Voice Science for them, and all of you.

We look forward to meeting you soon!

Successful speech therapy for a lisp or speech sound substitutions is often determined by how engaged you are with your practice and the level of accurate and attentive speech pathology support that you receive. 


While removing a lisp or fixing a speech distortion is a challenging task that will require lots of practice, we will assist you in developing a strategic plan to build your understanding of the target sound as well as increase your speech accuracy. Our online learning management system, Cadenza, will ensure that you have the resources to implement a successful home practice routine.
