AI Technical Summary
Technical Problem
Whispered speech is often difficult to understand due to its low energy level and susceptibility to interference, making it challenging for listeners to discern the spoken words effectively.
Method used
A method and device utilizing a deep neural network (DNN) to process whispered speech by extracting features through computations on overlapping data windows, performing a Fast Fourier Transform, and calculating log10 of the magnitude, followed by training the DNN model with loss function-based back-propagation to convert whispered speech into a non-whispered version.
Benefits of technology
The solution enhances the intelligibility of whispered speech by converting it into a more robust and understandable form, reducing interference and improving listener comprehension.
