String cheese plays a literally remarkable role in US patent 9424840B1, which was granted on August 23, 2016. As illustrated in the drawing you see here, the patent includes this passage:
FIG. 1A, for instance, illustrates the user providing an example request 128(1). Here, the user 104 states “I’d like some string cheese, please.” In response to generating an audio signal based on this audio, the device 106 may provide the audio signal to the remote computing resources 108. In response, the remote computing resources 108 may provide audio for output back to the device to aid in determining a domain associated with the user’s speech. Here, the remote computing resources 108 provide audio for asking the user the following question 128(2): “Are you wishing to shop or listen to music?” In this example, the remote computing resources 108 (and, more specifically, the dialog component 124) is attempting to determine whether the user’s speech should be associated with the “music” domain or the “shopping” domain.”
Inventors Gregory Michael, Hart, Frederic Johan Georges Deramat, Vikram Kumar Gundeti, John Daniel Thimsen, Allan Timothy Lindsay, Peter Paul Henri Carbon. and Scott Ian Blanksteen assigned the patent to Amazon Technologies Inc.
