1. A speech recognition system, comprising:
- a mobile communication device;
a user profile in the mobile communication device, the user profile to store acoustic data and a corresponding text transcript;
a speech recognition (“
SR”
) server to download the acoustic data and the corresponding text transcript that are stored in the user profile; and
a speech recognition engine to adapt an acoustic model based on the acoustic data.

Abstract
A speech recognition system includes a user profile to store acoustic data and a corresponding text transcript. A speech recognition (“SR”) server downloads the acoustic data and the corresponding text transcript that are stored in the user profile. A speech recognition engine is included to adapt an acoustic model based on the acoustic data.

6. A method of adapting an acoustic model to improve recognition accuracy, comprising:
-
loading accoustic data and a corresponding text transcript from a communication device to a speech recognition (SR) server, the acoustic data obtained from speech by a person; and adapting an acoustic model for the SR server based at least in part on the acoustic data from the communication device. - View Dependent Claims (7, 8, 9, 10, 11)

20. A processing system, comprising:
-
a user profile to store user-dependent speech data for adapting a speech recognition model, the user-dependent speech data comprising a text transcript and corresponding acoustic data obtained from speech by a person; a transmitter to transmit the user-dependent speech data from the user profile in the processing system to a speech recognition (“
SR”
) server, to allow the SR server to adapt a speaker-independent acoustic model into a revised acoustic model, based at least in part on the acoustic data from the user-dependent speech data; andthe transmitter to transmit voice queries from the person to the SR server, to be translated into text using the revised acoustic model. - View Dependent Claims (21, 22)
