Abstract

A method (200) of building a grammar with baseforms generated dynamically from user utterances can include the steps of recording (205) a user utterance, generating (210) a baseform using the user utterance, creating or adding to (215) a grammar rule using the baseform, and binding (230) the grammar rule in a grammar document of a voice extensible markup language program. Generating a baseform can optionally include introducing a new element to VoiceXML with attributes that enable generating the baseform from a referenced recording such as the user utterance. In one embodiment, the method can be used to create (235) a phonebook and a grammar to access the phonebook by repeatedly visiting a form containing the grammar rule with attributes that enable generating the baseform from the referenced recording.

Claims

1. A method of building a grammar with baseforms generated dynamically from user utterances, comprising the steps of:

recording a user utterance;

generating a baseform using the user utterance, the step of generating a baseform comprising introducing a new element to a voice extensible markup language (VoiceXML) with attributes that enable generating the baseform from a referenced recording;

performing at least one of creating a grammar rule using the baseform and adding to a grammar rule using the baseform;

binding the grammar rule of the performing step in a grammar document of a VoiceXML program; and

,

creating a user-accessable application and a grammar to access the application by repeatedly visiting a form containing the grammar rule with attributes that enable generating the baseform from the referenced recording.

2. The method of claim 1, wherein the referenced recording comprises the user utterance.

3. The method of claim 1, wherein the grammar rule is constructed using values of the attributes.

4. The method of claim 1, wherein the method further comprises the step of creating a grammar token when the new element is visited by a form interpretation algorithm.

5. The method of claim 4, wherein the method further comprises the step of controlling a composition of the grammar rule as the grammar token is added to the grammar rule.

6. The method of claim 1, wherein the method further comprises the step of creating a phonebook and a grammar to access the phonebook by repeatedly visiting a form containing the grammar rule with attributes that enable generating the baseform from the referenced recording.
