1. A computing device for handling spoken requests, the computing device comprising: an audio sensor; a training module to: prompt a user of the computing device for a plurality of neutral scripted requests; capture a first audio signal from the audio sensor comprising the plurality of neutral scripted requests by converting audio from the user from analog to digital format; prompt the user for a plurality of emotional scripted requests; capture a second audio signal from the audio sensor comprising the plurality of emotional scripted requests by converting audio from the user from analog to digital format; identify emotional features of each of the plurality of neutral scripted requests and each of the plurality of emotional scripted requests; and update a baseline emotional feature of a vocal pattern database based on the plurality of neutral scripted requests and the plurality of emotional scripted requests and the identified emotional features of each of the plurality of neutral scripted requests and the plurality of emotional scripted requests; a request analysis module to: receive a user request, the user request to represent a natural language request spoken by the user of the computing device; determine one or more audio features of the user request, wherein the one or more audio features comprises at least one of frequency, amplitude, or timbre; and identify an emotional feature of the user request, the emotional feature comprising a vocal pattern characteristic of the user request associated with one or more human emotions and the one or more audio features of the user request; an emotion recognition module to: compare the identified emotional feature to the baseline emotional feature of the vocal pattern database; and estimate an emotional state of the user request based on the comparison of the identified emotional feature to the baseline feature; and an output module to modulate a natural language response to the user request as a function of the emotional state and the vocal pattern database.
