SYSTEM AND METHOD FOR CONTROLLING A SPEECH RECOGNITION SYSTEM
First Claim
1. A method for controlling a speech recognition system, the method comprising:
- monitoring adaptive feature data about interactions between a user and the speech recognition system;
determining, via an adaptive controller, a first group of samples of the adaptive feature data;
creating, via the adaptive controller, a control chart based on the first group of samples, the control chart including a control limit;
determining, via the adaptive controller, a second group of samples of the adaptive feature data after creating the control chart;
calculating, via the adaptive controller, an arithmetic mean of each sample of the second group of samples to determine a sample mean;
comparing, via the adaptive controller, the sample mean to the control limit in order to identify unexpected performance of the speech recognition system; and
if the unexpected performance is identified, then adjusting the speech recognition system based on the identified unexpected performance.

Abstract
A method and system can control a speech recognition system in a vehicle. The method includes monitoring adaptive feature data about interactions between a user and the speech recognition system. The method includes determining a first group of samples of the adaptive feature data and creating a control chart based on the first group of samples. The control chart includes a control limit. The method further includes determining a second group of samples of the adaptive feature data after creating the control chart. Furthermore, the method includes calculating an arithmetic mean of each sample of the second group of samples to determine a sample mean, comparing the sample mean to the control limit in order identify unexpected performance of the speech recognition system. The method includes adjusting the speech recognition system based on the identified unexpected performance if the unexpected performance is identified.
