SYSTEM AND METHOD OF PROVIDING GENERATED SPEECH VIA A NETWORK
A system and method of operating an automatic speech recognition application over an Internet Protocol network is disclosed. The ASR application communicates over a packet network such as an Internet Protocol network or a wireless network. A grammar for recognizing received speech from a user over the IP network is selected from a plurality of grammars according to a user-selected application. A server receives information representing speech over the IP network, performs speech recognition using the selected grammar, and returns information based upon the recognized speech. Sub-grammars may be included within the grammar to recognize speech from sub-portions of a dialog with the user.
1 . A method comprising:
transmitting over a network an identification of a spoken dialog application, the spoken dialog application having an associated grammar;
transmitting user speech over the network; and
receiving synthesized speech in response to the user speech, wherein the user speech was recognized by the spoken dialog application using the associated grammar.
2 . The method of claim 1 , wherein recognizing the user speech using the associated grammar further comprises recognizing the user speech using a sub-grammar based on a sub-component of the user speech.
3 . The method of claim 2 , wherein the sub-grammar is associated with a task.
4 . The method of claim 1 , wherein the network is an internet protocol network.
5 . The method of claim 1 , wherein the spoken dialog application carries on a dialog with a user communicating with a client.
6 . The method of claim 1 , further comprising:
receiving information based on the synthesized speech over an internet protocol network from a client.
7 . The method of claim 1 , further comprising:
modifying the associated grammar based at least in part on the user speech.
8 . A system comprising:
a processor; and
a computer-readable storage medium storing instructions which, when executed on the processor, cause the processor to perform a method comprising:
transmitting over a network an identification of a spoken dialog application, the spoken dialog application having an associated grammar;
transmitting user speech over the network; and
receiving synthesized speech in response to the user speech, wherein the user speech was recognized by the spoken dialog application using the associated grammar.
9 . The system of claim 8 , wherein recognizing the user speech using the associated grammar further comprises recognizing the user speech using a sub-grammar based on a sub-component of the user speech.
10 . The system of claim 9 , wherein the sub-grammar is associated with a task.
11 . The system of claim 8 , wherein the network is an internet protocol network.
12 . The system of claim 8 , wherein the spoken dialog application carries on a dialog with a user communicating with a client.
13 . The system of claim 8 , the computer-readable storage medium storing additional instructions which, when executed on the processor cause the processor to perform a step comprising:
receiving information based on the synthesized speech over an internet protocol network from a client.
14 . The system of claim 8 , the computer-readable storage medium storing additional instructions which, when executed on the processor, cause the processor to perform a step comprising: modifying the associated grammar based at least in part on the user speech.
15 . A computer-readable storage medium storing instructions which, when executed by a processor, cause the processor, to perform steps comprising:
transmitting over a network an identification of a spoken dialog application, the spoken dialog application having an associated grammar;
transmitting user speech over the network; and
receiving synthesized speech in response to the user speech, wherein the user speech was recognized by the spoken dialog application using the associated grammar.
16 . The computer-readable storage medium of claim 15 , wherein recognizing the user speech using the associated grammar further comprises recognizing the user speech by using a sub-grammar based on a sub-component of the user speech.
17 . The computer-readable storage medium of claim 16 , wherein the sub-grammar is associated with a task.
18 . The computer-readable storage medium of claim 15 , wherein the network is an internet protocol network.
19 . The computer-readable storage medium of claim 15 , wherein the spoken dialog application carries on a dialog with a user communicating with a client.
20 . The computer-readable storage medium of claim 15 storing additional instructions which, when executed on the processor, cause the processor to perform a step comprising:
receiving information based on the synthesized speech over an internet protocol network from a client.
