Examples of Speech Separation Challenges

The task of separating speech in complex acoustic environments -- such as a single voice in a cocktail party -- is an extremely difficult challenge.

The emphasis is on real-world recordings i.e. the kinds of situations encountered in daily life. These examples are generally around the limit of normal listeners' abilities to discern particular voices.

This project is in its initial phase of defining the tasks and approaches. Here are some introductory illustrations of the kinds of problems we are facing:
