Method and apparatus for the provision of information signals based upon speech recognition
First Claim
1. In a speech recognition server forming a part of an infrastructure that wirelessly communicates with one or more subscriber units, each of the one or more subscriber units comprising a speech recognition client, a method for providing information signals to a subscriber unit of the one or more subscriber units, the method comprising steps of:
- receiving a parameterized speech signal, produced by the speech recognition client, from the subscriber unit;
performing speech recognition analysis on the parameterized speech signal to provide recognized utterances;
determining information signals based on the recognized utterances; and
responsive to the recognized utterances, providing the information signals to the subcriber unit.

Abstract
A wireless system comprises at least one subscriber unit in wireless communication with an infrastructure. Each subscriber unit implements a speech recognition client, and the infrastructure comprises a speech recognition server. A given subscriber unit takes as input an unencoded speech signal that is subsequently parameterized by the speech recognition client. The parameterized speech is then provided to the speech recognition server that, in turn, performs speech recognition analysis on the parameterized speech. Information signals, based in part upon any recognized utterances identified by the speech recognition analysis, are subsequently provided to the subscriber unit. The information signals may be used to control the subscriber unit itself; to control one or more devices coupled to the subscriber unit, or may be operated upon by the subscriber unit or devices coupled thereto.
