The Diagnosis
You have the leads, the funnel, the buyers but do you have the voice to convert the deal?
- You go to open your mouth, and the tone is not there…
- There’s tightening in your throat. You sound croaky.
- It’s out of control, cadence is slipping…Or your voice cracks.
- It’s just so tired and unpredictable.
If you’ve been trying to get on top of your vocal clarity so that you can bring energy to your sales conversations, pitching and deals, then pay close attention.
There’s a reason why your voice is not working for you (or your funnel).
Proof
All the OGs of sales have told you- tonality is the difference between sales success and struggling to close.

The way you allow your message to come across is through tonality and body language.

Your voice alone can be such an art. When I was teaching hostage negotiation, I knew a hostage negotiator might not even say the right things — but if they had a great voice, we were probably going to be all right.

A TOP 1% Salesperson is like a TOP 1% Hollywood actor: they follow a script, but it doesn't seem scripted to you. Why? Because they are taught advanced tonality and body language skills.

The way you say something is often more important than what you say. Your voice carries your true belief system right to the customer's ear.

Charismatic voice tone training ensures you sound confident. It builds your conviction in the sales conversation because you hear vocal boldness as you speak.
Effective voice tonality creates the connection, credibility and conviction that reassures your customer, increasing conversion rates by at least 50%.
The Instrument
Your voice moves up to 220 times a second — and can be calibrated like any precision instrument.
Your vocal folds are under 2mm long. The Voice Tone Test measures six elements — muscle health, range, breath coordination, fatigue risk, expression, intonation — to determine exactly what your instrument needs.

Meet Dr. Sarah Lobegeiger de Rodriguez: Executive Eloquence Specialist
PhD (Opera), MMus, MSpPath, Certified Practicing Speech Pathologist
The Prognostic Power of My Work
As a trained speech pathologist, opera singer and medical founder, I know the many barriers to high-performance communication.
In opera, the expectation is that you step on stage and complete a perfect vocal performance despite nerves, so I've done a lot of heavy lifting there.
Then speech pathology gives me the science-backed clinical tools to analyse how communication works and structure viable speaking goals for my clients so they stick and they can finally communicate with unwavering confidence and skill.
Diagnostics create valid outcomes.
My communication calibration system is rigorously grounded in voice science, opera performance training, and robust executive communication research evidence. And I want to share that with you, no matter where you are, so that you know where you stand, and have a proven plan to excel at your professional communication.
You already have the skill, perspective and vision. But it takes a discerning eye and clinical insight to spot the leaks, triggers and gaps in your speaking system.
The first step isn't a generic sales coaching program, a new AI tool, nor a vague sales-driven curiosity call. The first step is the Voice tone Test which enables you to establish personalised baselines through a robust, evidence-based process.

What Clients Say About Working With Dr Sarah

The progression is smart, starting with voice mechanics — resonance, projection, warm-ups — which created a foundation that made everything click. By the time we hit persuasion models, storytelling and charisma, I had the vocal control to actually deliver on those frameworks.

Questions
Frequently Asked Questions
Who is the Voice Tone Test for?
If you’re wanting to work on voice tonality for sales so that you gain functional clarity, energised and intentional inflection and emotional contagion needed to convert leads, secure sales, and close high ticket deals, this appointment is for you.
How long does it take to improve my vocal presence?
The Voice tone test will diagnose your current vocal profile against your seller positioning and daily needs. I will be investigating:
- Voice muscle health, tonal clarity and consistency
- Vocal range, power and flexibility
- Breath coordination
- Usage requirements, fatigue risks, projection needs
- Vocal expression, tonality and sonic charisma (presence) when speaking
- Intonation, melody and emphasis
This information is then used to forecast the recommended time frame to reach your desired outcome. Diagnosis predicts a realistic plan and recommendation.
Which program will I need?
Don’t worry about this option until your vocal presence profile is completed. Dr Sarah will give you solid and candid recommendations for options once she has diagnosed your voice and met you.
Vocal optimisation is a detailed process, especially since vocal calibration is a fine motor skill.
It takes time to learn to use your voice effectively and produce the voice muscle agility, coordination and stamina needed and then unite it to your mental state to attain intentional consistency. This is why Dr Sarah will train you in a research approach based on behavioural change, motor learning, opera acoustics principles and embodiment theory that do not fit into a single session approach.
Muscle memory matters. In the early stages of training with Dr Sarah you will learn scientific methods to strengthen learning as well as how to understand, evaluate and enhance your vocal health, power and functional expression.
I’m not in Australia, are online sessions just as effective for voice tone training as in person?
Dr Sarah has been delivering engaging and effective voice training online and in person for over thirteen years with a 100% success rate. Online sessions do not alter outcomes. What matters the most is that you work with a skilled voice expert who will handle your voice needs with clinical grade care and build the muscle integrity to make you the vocal athlete + artist sales requires you to be.
