In modern contemporary singing, there are two reigning champs of vocal technique: Speech Level Singing (SLS) and Estill Voice Training (EVT). While they share some similarities, they differ in significant ways. If you’re a singer trying to decide which method to follow, we’re here to help! In this article, we’ll break down each method so you can make an informed decision for your artistic journey. Let’s dive in!

What is Speech Level Singing?

Speech Level Singing, also known as SLS, is a popular vocal technique created by the now-famed vocal coach Seth Riggs. SLS gained popularity thanks to the stars who used the method, such as Michael Jackson, Ray Charles, and Stevie Wonder.

The main focus of Speech Level Singing is developing a smooth and connected voice, without breaks or gaps between head voice and chest voice. Whether hitting high or low notes, there should be no straining or unnecessary larynx movement. The idea is that singers should sing at “speech level,” maintaining a natural and relaxed position of the voice.

What is Estill Voice Training?

Estill Voice Training, also known as EVT, is a vocal training method developed by educator and classical singer Jo Estill. Some stars who have incorporated EVT into their training include Madonna, Cynthia Erivo, and Anne Hathaway.

EVT is grounded in scientific knowledge of the voice, focusing on the anatomy and function of vocal production. By building an understanding of the voice’s physical structures, students can explore a wide range of sounds and tonal textures. EVT encourages vocalists to think beyond their initial vocal identity and discover the full potential of their voice.

How Are They Similar?

Both SLS and EVT are in-depth vocal training programs endorsed by many successful artists and educators. Each system is systematic, relevant to contemporary singing, and covers multiple aspects of vocal performance. With guidance from a qualified teacher, students following either method can expect to improve both their technical understanding and practical skills as singers.

Where Do They Differ?

While both programs aim to develop strong and versatile voices, their approaches and focus areas differ in meaningful ways. Check out the chart below for a comparison!

Does Either System Miss Anything?

Both programs emphasize technique and the physical aspects of vocal production, but they tend to undervalue musical fundamentals like ear training and rhythm. For any serious singer, supplementing either method with a program that builds these musical skills is highly recommended.

Which One Is Right for You?

As with most things in music, there is no “best.” The choice between SLS and EVT depends entirely on your personal goals and preferences:

• If you’re looking for applied skills to make performing smoother and more enjoyable, SLS might be the better fit. With its focus on connecting your vocal registers and minimizing strain, SLS is ideal for singers in popular genres.
• On the other hand, if you’re curious about the broader creative possibilities of your voice—tone, color, and versatility—EVT may be the way to go. With EVT, you’ll gain a deep understanding of how the voice works and the tools to explore its full potential in any situation.
