Sculpting speech from noise, music, and other sources

Intelligible speech can be generated by passing a signal through a time-frequency mask that selects which information to retain, even when the signal is speech-shaped noise, suggesting an important role for the mask pattern itself.

Description
Summary:Intelligible speech can be generated by passing a signal through a time-frequency mask that selects which information to retain, even when the signal is speech-shaped noise, suggesting an important role for the mask pattern itself. The current study examined the relationship between the signal and the mask by varying the availability of target speech cues in the signal while holding the mask constant. Keyword identification rates in everyday sentences varied from near-ceiling to near-floor levels as the signal was varied, indicating that the interaction between the signal and mask, rather than the mask alone, determines intelligibility.
