Formant Booster keeps conversation rolling

Formant Booster provides advanced listening comfort by focusing on recovering speech contrast through speech enhancement. This significantly eliminates any possible breakdown in speech structure resulting from hearing loss, background noise, and signal processing.

Restores contrast of speech

Changes in the voice’s dynamic range generally result in spectral smearing that is degrading intelligibility of voiced speech. Formant Booster, an active speech enhancement scheme, brings back the sharpness to smeared formants by merging two operations:
First, it uses signal statistics to detect and analyze voiced speech—as a combination of time and frequency statistics.

Second, it modifies the relevant voiced speech by boosting its formants, or more accurately, their spectral peaks. This greatly enhances speech intelligibility, which makes it easier to communicate and keep conversation rolling.
