1. A method of determining hint words for automated speech recognition, the method comprising:
determining, using control circuitry, a first set of terms comprising terms that are most frequently occurring terms from speech input to a voice interface system;
determining, using the control circuitry, a second set of terms that are most frequently occurring terms arising during a predetermined time period of operation of the voice interface system;
selecting as a first set of hint words facilitating operation of an automated speech recognition application, the first set of hint words comprising common terms of the first set of terms and the second set of terms;
selecting a second set of hint words comprising a plurality of terms that are not among the common terms from the first set of terms or the second set of terms; and
transmitting, using the control circuitry, the hint words to the automated speech recognition application, the hint words comprising the first set of hint words and the second set of hint words.
