System and method of providing generated speech via a network
View Patent ↗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 of synthesizing speech from a server remotely accessible over a network, the method comprising, at the server:
receiving over a network an identification of a spoken dialog application from a plurality of spoken dialog applications, the identified spoken dialog application having an associated grammar;
recognizing received user speech from a user using the associated grammar; and
transmitting synthesized speech to the user from the server in response to the recognized user speech information over the network.
2. The method of claim 1 , further comprising:
identifying a sub-portion of a dialog with a user;
selecting a sub-grammar according to the identified sub-portion of the dialog; and
recognizing speech from the user for the identified sub-portion of the dialog using the selected sub-grammar.
3. The method of claim 2 , wherein each sub-grammar is associated with a task.
4. The method of claim 1 , wherein the associated grammar is identified by a universal resource locator (URL) compatible address associated with the spoken dialog application.
5. The method of claim 1 , wherein the network is an internet protocol network.
6. A system for synthesizing speech over a network, the system comprising:
a module configured to receive an identification over a network of a spoken dialog application from a plurality of spoken dialog applications, the identified spoken dialog application having an associated grammar;
a module configured to recognize received user speech from a user using the associated grammar; and
a module configured to transmit synthesized speech from the server to the user in response to the recognized user speech input information over the network.
7. The system of claim 6 , further comprising:
a module configured to identify a sub-portion of a dialog with a user;
a module configured to select a sub-grammar according to the identified sub-portion of the dialog; and
a module configured to recognize speech from the user for the identified sub-portion of the dialog using the selected sub-grammar.
8. The system of claim 7 , wherein each sub-grammar is associated with a task.
9. The system of claim 6 , wherein the associated sub-grammar is identified by a universal resource locator (URL) compatible address associated with the spoken dialog application.
10. A computer readable medium storing instructions for controlling a computing device for providing speech over a network, the instructions comprising:
receiving an identification over a network of a spoken dialog application from a plurality of spoken dialog applications, the identified spoken dialog application having an associated grammar;
recognizing received user speech from a user using the associated grammar; and
transmitting synthesized speech from the server to the user in response to the recognized user speech information over the network.
11. The computer readable medium of claim 10 , wherein the network is an internet protocol network.
12. The computer readable medium of claim 10 , wherein the instructions further comprise:
identifying a sub-portion of a dialog with a user;
selecting a subgrammar according to an identified sub-portion of the dialog; and
recognizing speech from the user for the identified sub-portion of the dialog using the selected sub-grammar.
13. The computer readable medium of claim 12 , wherein each sub-grammar is associated with a task.
14. The computer readable medium of claim 10 , wherein the an associated grammar is identified by a universal resource locator (URL) compatible address associated with the spoken dialog application.
15. A method of synthesizing speech from a server remotely accessible over a network, the method comprising, at the server:
receiving speech information from a user over a network;
recognizing the speech information using a grammar selected from a plurality of grammars; and
transmitting synthesized speech from the server to the user in response to the recognized user speech information over the network.
16. The method of claim 15 , wherein the network is an internet protocol network.
17. The method of claim 15 , wherein the grammar is selected based on a received identification of a spoken dialog application having the selected grammar.
