Method and apparatus for the provision of information signals based upon speech recognition

Abstract

A wireless 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.

Description

[0001]The present application, Reissue application Ser. No. 13 / 891,262 filed on May 10, 2013, is a reissue application Ser. No. 09 / 412,119 filed on Oct. 5, 1999, of U.S. Pat. No. 6,868,385. Reissue application Ser. No. 13 / 891,273, filed on May 10, 2013, is a continuation of the present reissue application.TECHNICAL FIELD[0002]The present invention relates generally to communication systems incorporating speech recognition and, in particular, to the provision of information signals to subscriber units and / or accompanying devices based upon speech recognition analysis.BACKGROUND OF THE INVENTION[0003]Speech recognition systems are generally known in the art, particularly in relation to telephony systems. U.S. Pat. Nos. 4,914,592; 5,475,791; 5,708,704; and 5,765,130 illustrate exemplary telephone networks that incorporate speech recognition systems. A common feature of such systems is that the speech recognition element (i.e., the device or devices performing speech recognition) is typ...

AI Technical Summary

Benefits of technology

The present invention is a subscriber unit that can be used in in-vehicle systems. It includes processing components that are normally part of the vehicle, such as a general-purpose processor and a digital signal processor. These components are combined to form a single unit, although alternative embodiments may combine or split them. The subscriber unit has its own memory for storing software functions. By using stored software routines, the processing components can be programmed to implement at least a portion of the functionality of the present invention. The technical effects of this invention are that it provides a flexible and customizable solution for in-vehicle systems, allowing for seamless integration with existing infrastructure and improved user experiences.

Problems solved by technology

However, it is uncertain at this time what features and services the Aurora Project will enable.

However, there does not appear to be any significant solutions defining how speech recognition technology can be incorporated into telematics systems.
