Speech Level Singing™ (SLS) is a revolutionary vocal training technique that maximizes your vocal abilities in any style of singing.

From Opera to Rock, Jazz to Pop or R&B, over 120 Grammy award winners use it. SLS has also been practiced by Academy Award winning actors and industry leaders to perfect their vocal presence and empower them in speech.

In many cases SLS rehabilitates vocal damage, caused by poor teaching or years of abuse that could otherwise limit or even end a career, or worse - require continual medical intervention. SLS training will improve your voice allowing you to sing safely and with greater range.

SLS teachers have completed educational requirements per their level of certification. These levels are 1 through 5. A Level 5 teacher is expected to be able to give information, instruction, and execute a vocal lesson as true to the Speech Level Singing™ technique as intended by Seth Riggs.

The minimum requirement for a Level 5 is a 10-year commitment. Graduation from one level to another requires at least two years of continual study including proficiency testing. These are the ONLY teachers privileged to use Seth Riggs' name or the Speech Level Singing™ trademark.
