Latest Patents

Yeonsuk Cho holds 1 patent for his invention titled "Systems and methods for evaluating difficulty of spoken text." This patent describes a process for assigning a difficulty score to a speech sample. The method involves performing speech recognition on a digitized version of the speech sample using an acoustic model to generate word hypotheses. Time alignment is then conducted between the speech sample and the word hypotheses to associate them with corresponding sounds. A first difficulty measure is determined based on the word hypotheses, while a second measure is derived from the acoustic features of the speech sample. Ultimately, a difficulty score for the speech sample is generated based on these two measures.
