"Use case" perhaps wasn't the right word for me to use. Maybe "applications" would have been a better word. What this enables is speech-to-speech applications in embedded devices. (From my quick scan) it doesn't seem to do anything around other ML applications that OpenAI could potentially be involved in, such as speech-to-text, text-to-speech, or computer vision.

But yeah, once I figured out that this enables streaming speech-to-speech applications on embedded devices, then it's easy to think up use cases.
