Forbrain is the flagship product of Sound for Life and has inherited its science from the Tomatis Method, the most advanced program in Sound Therapy which has evolved over a period of sixty years. Forbrain is an award-winning neural device that has shown conclusive results in enhancing language and speech fluency. Built with bone conduction technology and a unique dynamic filter, the device provides the user instantaneous feedback of their own voice which creates an enhanced auditory-feedback loop.

Forbrain helps people to improve speech fluency, pronunciation, sound discrimination, and rhythm, for clearer and more effective communication.


What is the Auditory Feedback Loop?

It is the natural process by which every individual perceives, analyses, assimilates, and continuously adjusts the information received and produced through sound.

To function properly, this audio-vocal loop draws on the abilities of auditory discrimination, phonological awareness, and integration of rhythm that each person activates effortlessly. These skills are natural to human function and go far beyond speech. They are necessary for all learning processes.

How does Forbrain enhance the Auditory Feedback Loop?

Forbrain headphones amplify high-frequency vibration and simultaneously diminish low-frequency to help the user create and process sound. The patented electronic dynamic filter blocks out environmental noise—isolating and amplifying the user’s voice, giving the nervous system a solid sensory workout. It also enhances long vowels and other sounds critical to the construction of language. The resulting sound is delivered to the nervous system and the brain through bone conduction which is 10 times faster than air conduction.

The user hears their own voice filtered with alternating contrasts. This shifting of sound or alternation will occur mainly at the beginning of spoken words and long vowels; they are also called the “clear sounds” that are essential for building language. By hearing and choosing this new perception of sound play, the user instantly and subconsciously improves the quality and rhythm of the voice. A continuous workout with Forbrain headphones leads to:

  • Cortical Stimulation - essential for speech, learning, attention, memory, and social communication.
  • Vestibular Stimulation - essential for managing motion, core stability, motor planning, balance, and spatial orientation.


Most Speech and Language Pathologists who recommend Forbrain are successfully working with clients who have:

Speech Sounds Disorders - it is the inability to make certain sounds or put sounds together into words. E.g.: articulation or phonological disorders, apraxia of speech, or dysarthria.

Language Disorders - it is the inability to understand what we hear or read and not being able to communicate our thoughts to others. In adults, this problem may be called aphasia.

Learning Disorders - learning encompasses the ability to read and write. People with speech and language disorders may also have trouble reading, spelling, and writing.

Social Communication Disorders - it is the inability to follow rules e.g. how to take turns, how to talk to different people, or how close to stand to someone when talking. This condition is common among individuals who have Autism Spectrum Disorder.

Voice - it is the inability to have control over how our voice sounds. One may sound hoarse, lose their voices easily, talk too loudly or nasally, or be unable to make sounds (Selective Mutism).

Fluency - also called stuttering, is how well speech flows. Someone who stutters may repeat sounds, like t-t-t-table, use "um" or "uh," or pause a lot when talking. 

Cognitive Communication - Problems may involve memory, attention, problem-solving, organization, and other thinking skills.

Who can use Forbrain? 

Forbrain is a universal tool, it can be used by anyone from the age three and above. Forbrain is recommended by over 5000+ professionals around the world as the go-to tool to improve learning. 

Activities to do with Forbrain

Forbrain can be used as a stand-alone tool or as a complementary tool to various speech therapies. To ensure successful results, users are recommended to practice daily for 20 minutes for at least 40 days. The following are a few examples of how one could utilize the device independently and jointly:

  • Individually – Read books or articles aloud, complete pronunciation and conversation exercises in native or foreign languages, practice monologues, review previous lessons, sing, etc.
  • With a partner/parent – Perform playwright literature, quiz vocabulary pronunciation and memorization, participate in role-playing games, etc.
  • With a professional – Run through any variety of verbal exercises during work sessions with a therapist, teacher, or coach.



An independent clinical study conducted by Carles Escera, PhD, Professor, Director of Institute for Brain, Cognition and Behavior, University of Barcelona investigated, in a double-blind controlled experiment, the potential effects of the Forbrain on natural speech. He found that the device "induced changes in voice quality, in particular, a strengthening of voice robustness.” Observation of the results prove that the Forbrain is an effective, low-cost treatment option "on a range of speech, language, and communication disorders.” 

This study was published in one of the most prestigious journals, American Speech-Language-Hearing Association (ASHA).


Kara said, "The success I have experienced using Forbrain in my practice comes mostly from its variety of applications. If a child has an apparent speech or language delay, I may test the use of the Forbrain during the initial evaluation to see how a child responds." Read More.

Charlotte explained, "Everyone is a good candidate for Forbrain." She works with individuals between the ages of three and seventy for all types of difficulties. Clients such as students who want to improve their learning abilities and elderly people who want to maintain their level of cognitive function have all benefited from the use of Forbrain and her approaches.
