Abstract

A system and method for improving voice recognition processing at a server system that receives voice input from a remotely located user system. The user system includes a microphone, a processor that performs front-end voice recognition processing of the received user voice input, and a communication component configured to send the front-end processed user voice input to a destination wirelessly over a network. The server system includes a communication component configured to receive the sent front-end processed user voice input, and a processor configured to complete voice recognition processing of the sent front-end processed user voice input.

Claims

1. A method for digital signal manipulation, comprising:

receiving an acoustic analog signal at a user system;

converting the analog signal to a digital signal;

forming a processed digital signal;

detecting user speech in the processed digital signal;

if user speech is detected in the processed digital signal;

packaging the user speech into speech packets to form a packaged voice signal;

selecting a transmission format compatible with the packaged voice signal; and

transmitting the packaged voice signal to a server; and

receiving non-acoustic data at the user system; and

if user speech is not detected in the processed digital signal,

packaging the non-acoustic data into data packets to form a packaged data signal;

selecting a transmission format compatible with the packaged data signal; and

transmitting the packaged data signal to a server.

2. The method of claim 1, wherein the packaged data signal is transmitted to the server using a maximum possible bandwidth.

3. A method for digital signal manipulation, comprising:

receiving an acoustic analog signal at a user system;

converting the analog signal to a digital signal;

forming a processed digital signal;

detecting user speech in the processed digital signal; and

if user speech is detected in the processed digital signal,

packaging the user speech into speech packets to form a packaged voice signal;

selecting a transmission format compatible with the packaged voice signal; and

transmitting the packaged voice signal to a server, wherein if user speech is detected in the processed digital signal, further comprising;

evaluating the processed digital signal to determine whether data exist that enhances speech detection and matching at the server; and

if data front the processed digital signal exist to be transmitted to the server to enhance speech detection and matching at the server,

packaging the data from the processed digital signal into data packets; and

interspersing data packets with the voice packets.

4. A method for digital signal manipulation, comprising:

receiving an acoustic analog signal at a user system;

converting the analog signal to a digital signal;

forming a processed digital signal;

detecting user speech in the processed digital signal; and

if user speech is detected in the processed digital signal,

packaging the user speech into speech packets to form a packaged voice signal;

selecting a transmission format compatible with the packaged voice signal; and

transmitting the packaged voice signal to a server, and if user speech is not detected in the processed digital signal,

receiving non-acoustic data at the user system;

packaging the processed digital signal into data packets to form a packaged data signal;

selecting a transmission format compatible with the packaged data signal; and

transmitting the packaged data signal to a server.

5. The method of claim 4, wherein the packaged data signal is transmitted to the server using a maximum possible bandwidth.

6. A method for digital signal manipulation, comprising:

receiving an acoustic analog signal at a user system;

converting the analog signal to a digital signal;

forming a processed digital signal;

detecting user speech in the processed digital signal; and

if user speech is detected in the processed digital signal,

packaging the user speech into speech packets to form a packaged voice signal;

selecting a transmission format compatible with the packaged voice signal; and

transmitting the packaged voice signal to a server, further comprising;

evaluating the processed digital signal to determine whether data exist that enhances speech detection and matching at the server; and

if data from the processed digital signal exists to be transmitted to the server to enhance speech detection and matching at the server,

packaging the data from the processed digital signal into data packets; and

interspersing data packets with the voice packets.
