Abstract

A method and a system for voice transmission control. The method comprises: receiving, by a voice answering device, a voice command and transmitting the voice command to a sound control server through a network data transmission channel; recognizing, by the sound control server, the voice command, generating corresponding VXML control information based on a recognition result, and transmitting the VXML control information to the voice answering device through the network data transmission channel; and performing, by the voice answering device, an operation according to the received VXML control information. With this method, the architecture and workflow of the communication system can be simplified, and the difficulty of design thereof can be reduced.

Claims

1. A voice transmission control method, comprising:

receiving, by a voice answering device, a voice command and transmitting the voice command to a sound control server through a network data transmission channel;

performing, by the voice answering device, an operation according to the received VXML control information, wherein the VXML control information is first voice extensible markeup language (VXML) control information, the first VXML control information comprises;

a storing address of a voice extensible markeup language (VXML) dialogue table corresponding to the voice command, and a first control command for controlling the voice answering device to execute the VXML dialogue table;

wherein the performing, by the voice answering device, an operation according to the received VXML control information comprises;

obtaining and executing, by the voice answering device, the VXML dialogue table according to the first control command, prompting a user to perform an inputting operation, and transmitting the voice command inputted by the user to the sound control server through the network data transmission channel.

2. The voice transmission control method according to claim 1, wherein the VXML control information is second VXML control information, the second VXML control information comprises:

an address of a VXML script corresponding to the voice command, and a second control command for controlling the voice answering device to execute the VXML script;

wherein the performing, by the voice answering device, an operation according to the received VXML control information comprises;

obtaining and executing, by the voice answering device, the VXML script according to the second control command.

3. The voice transmission controlling method according to claim 2, wherein the second VXML control information further comprises target number information.

4. The voice transmission control method according to claim 1, further comprising:

converting, by a voice conversion device, the voice command received by the voice answering device into corresponding text data;

wherein the transmitting the voice command to a sound control server through a network data transmission channel comprises;

transmitting, by the voice answering device, the text data corresponding to the voice command to the sound control server through the network data transmission channel.

5. The voice transmission controlling method according to claim 4, wherein the recognizing, by the sound control server, the voice command comprises:

performing, by the sound control server, fuzzy matching for the text data corresponding to the voice command to recognize the voice command.

6. The voice transmission control method according to claim 1, wherein the voice answering device receives the voice command through a man-machine interaction interface or through a remote control manner.

7. The voice transmission control method according to claim 1, before the receiving, by a voice answering device, a voice command, further comprising:

receiving, by the voice answering device, a triggering operation by a user;

transmitting an operation request to the sound control server according to the triggering operation; and

transmitting, by the sound control server, the corresponding VXML control information to the voice answering device according to the operation request,

wherein the receiving, by a voice answering device, a voice command comprises;

receiving, by the voice answering device, the voice command according to the VXML control information.

8. A voice transmission control system, comprising a voice answering device and a sound control server,

wherein the voice answering device is configured to:

receive a voice command, transmit the voice command to the sound control server through a network data transmission channel, and perform an operation according to the received voice extensible markeup language (VXML) control information;

wherein the sound control server is configured to;

recognize the voice command, generate corresponding voice extensible markeup language (VXML) control information based on a recognition result, and transmit the VXML control information to the voice answering device through the network data transmission channel, and

wherein the voice answering device comprises;

a first receiving unit configured to receive the voice command;

a first transmitting unit configured to transmit the voice command to the sound control server through the network data transmission channel; and

an operating unit configured to perform the operation according to the received VXML control information,

wherein the sound control server comprises;

a recognizing unit configured to recognize the voice command;

a generating unit configured to generate the corresponding VXML control information based on the recognition result; and

a second transmitting unit configured to transmit the VXML control information to the voice answering device through the network data transmission channel.

9. The voice transmission control system according to claim 8, wherein the VXML control information generated by the generating unit is first VXML control information, the first VXML control information comprises:

a storing address of a VXML dialogue table corresponding to the voice command, and a first control command for controlling the voice answering device to execute the VXML dialogue table;

wherein the operating unit is further configured to obtain and execute the VXML dialogue table according to the first control command and prompt a user to perform an inputting operation;

wherein the first transmitting unit is further configured to transmit the voice command inputted by the user to the sound control server through the network data transmission channel.

10. The voice transmission control system according to claim 8, wherein the VXML control information generated by the generating unit is second VXML control information, the second VXML control information comprises:

an address of a VXML script corresponding to the voice command, and a second control command for controlling the voice answering device to execute the VXML script;

wherein the operating unit is further configured to obtain and execute the VXML script according to the second control command.
