Another Success For Forbrain®!

01 Jun 2018

A study published in the Journal of Speech, Language, and Hearing Research (ASHA.org) proves the effectiveness of Forbrain® in modifying the speech of its users!

The paper called “The Potential Effect of Forbrain as an Altered Auditory Feedback Device”, is co-authored by Professor Escera, and his colleagues Mr. López-Caballero and Mrs. Gorina-Careta. It was published online in the “Journal of Speech, Language and Hearing Research”, or ASHA, the American, professional, scientific, and credentialing association for 182,000 members and affiliates who are audiologists; speech-language pathologists; speech, language, and hearing scientists; audiology and speech-language pathology support personnel; and students.

In this study, Professor Escera and his colleagues demonstrated with a double-blind controlled design that Forbrain modifies the input voice according to a Baxandall equalizer and that this altered auditory feedback via the device’s bone conductor alters the voice of the speaker.

The results of this study indicate the effectiveness of Forbrain® in modifying the speech of its users. It is suggested that Forbrain® works as an altered auditory feedback device. It may hence be used as a clinical device in speech therapy clinics.

Participants were instructed to read aloud a text of their choice during three experimental phases: baseline, test, and post-test, while wearing a Forbrain® headset. Critically, for half of the participants (Forbrain group) the device was turned on during the test phase, whereas for the other half (control group) the device was kept off. Voice recordings were analyzed to derive six quantitative measures of voice quality over each of the phases of the experiment.

A significant Group X Phase interaction was obtained for the smoothed cepstral peak prominence, a measure of vocal harmony, and for the trend line of the long-term average spectrum, a measure of voice robustness, this latter surviving Bonferroni correction for multiple comparisons.

The results of the study indicate the effectiveness of Forbrain® in modifying the speech of its users. It is suggested that Forbrain® works as an AAF device. It may hence be used as a clinical device in speech therapy clinics, yet further studies are warranted to test its usefulness in clinical groups.
