Abstract
Systems and methods for determining hint words that improve the accuracy of automated speech recognition (ASR) systems. Hint words are determined in the context of a user issuing voice commands in connection with a voice interface system. Terms are initially taken from most frequently occurring terms in operation of a voice interface system. For example, most frequently occurring terms that arise in electronic search queries or received commands are selected. Certain of these terms are selected as hint words, and the selected hint words are then transmitted to an ASR system to assist in translation of speech to text.

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 or 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.
A system for determining hint words for automated speech recognition, the method comprising:
- processing circuitry configured to:
- determine a first set of terms comprising terms that are most frequently occurring terms from operation of a voice interface system, the most frequently occurring terms selected from one or more of terms of speech input to the voice interface system;
- determine a second set of terms that are most frequently occurring terms arising during a predetermined time period of operation of the voice interface system;
- select 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;
- and
- select, if less than a predetermined number of common terms are selected, a second set of hint words comprising a plurality of terms from the first set of terms that are not among the common terms;
- and
- input/output circuitry configured to:
- transmit the first set of hint words and the second set of hint words to the automated speech recognition application.
