Signal processing for a visual hearing aid
Ellen McDonald, Hans Kunov, Willy Wong · Canadian acoustics · 2001
Two strategies were devised to try and detect plosives and fricatives based on the high frequency energy content. The first strategy is High Frequency Energy (HFE) and the second is the High Frequency Energy Ratio (HFER). Each detection strategy was carried out using the sentence "Jeff toy go cart never worked" as spoken by four male and two female speakers. Through this example, the validity of each method was determined.
