If you're new to voice training or want to take your singing to the next level, mastering various vocal techniques will help.
Two of the most talked-about approaches today are Speech Level Singing (SLS) and Estill Voice Training (EVT). Each method offers its own way of helping singers build control, confidence and healthy vocal habits.
That being said, in this article we'll describe each approach, how they differ and how to choose the best voice training in Toronto for your needs.
Whether you're an absolute beginner or someone returning to singing after a break, these two techniques can give you the tools to grow and perform with confidence. Let’s break it all down…
What Is Speech Level Singing?
Speech Level Singing, also known as SLS, was developed by Seth Riggs and is based on the idea that singing should feel as easy and natural as speaking.
This approach focuses on maintaining larynx stability, employing little strain and seamlessly merging chest and head sound throughout your vocal range.
The approach helps vocalists avoid strain by allowing them to maintain a balanced, speech-like tone across their full range. Singers learn to generate a cohesive sound from bottom to top rather than "pushing" for high notes or switching between vocal ranges. It's extremely beneficial to vocalists in pop, R&B, musical theatre and other modern genres.
Some of the key principles of SLS include:
Singing with a relaxed, neutral larynx.
Mixing chest and head voice for smooth transitions.
Supporting the voice with breath control and posture.
Students who use this approach generally notice increased stamina, a stronger middle voice and a more steady tone. Touring professionals and voice teachers frequently employ SLS since it focuses on comfort and health.
What Is Estill Voice Training?
Estill Voice Training, or EVT, developed by Jo Estill, takes a more scientific and anatomical approach to singing.
Rather than providing generic exercises, EVT teaches singers how to control particular elements of their vocal anatomy, such as the tongue, soft palate, false vocal folds and larynx, using direct and reproducible exercises.
This approach is noted for its flexibility. EVT allows vocalists to experiment with a variety of voice characteristics and styles. From opera to rock to speech therapy, EVT may be tailored to almost any voice enhancing goal.
Some key features of EVT include:
Focused control of vocal structures.
Use of specific vocal qualities like belt, falsetto, twang and sob.
Emphasis on vocal health and efficiency.
One of the most significant benefits of EVT is that it helps vocalists to properly grasp how their voice works. This makes it popular among voice teachers, therapists and actors, as well as performers themselves.
Comparing SLS and EVT: What's the Difference and How To Choose?
While both Speech Level Singing and Estill Voice Training are great methods for voice development, they have different philosophies and serve slightly different purposes.
SLS
SLS focuses on singing with ease and flow. It seeks to make singing more natural by balancing your voice ranges. It's more intuitive and emphasizes sensation.
EVT
EVT breaks things down technically, allowing vocalists to have mastery over all aspects of vocal production. It is more analytic and scientific.
How To Choose
If you’re someone who enjoys structure, detailed instruction and experimenting with different sounds, EVT might be a great fit. If you prefer to learn by feel and are focused on vocal comfort and consistency, SLS might be more your style.
Many singers benefit from both approaches and may even combine tactics depending on the genre or vocal difficulty at hand.
