A system generates an audio challenge that includes a first voice and one or more second voices, the first voice being audibly distinguishable, by a human, from the one or more second voices. The first voice conveys first information and the second voice conveys second information. The system provides the audio challenge to a user and verifies that the user is human based on whether the user can identify the first information in the audio challenge.

Audio human verification

A system receives a spoken utterance, identifies at least one keyword within the spoken utterance, and identifies a function using the identified at least one keyword. The system further performs the identified function on at least a portion of the spoken utterance to create a voice file.

Adding audio effects to spoken utterance

A computer implemented method for automatically processing a data request comprising accessing a voice signal from a caller, determining geographic information associated with the caller from telephone network information associated with a call made by the caller, and retrieving a speech recognition grammar customized to the geographic information associated with the caller. The method further includes recognizing the voice signal by matching the voice signal to an entry of the speech recognition grammar and providing a directory listing to the caller based on the entry of the speech recognition grammar. The selected grammar may be customized to bias speech recognition to more frequently recognize cities local to the geographic information.

Method and system for selecting grammars based on geographic information associated with a caller

Described are methods and systems for reducing the audible gap in concatenated recorded speech, resulting in more natural sounding speech in voice applications. The sound of concatenated, recorded speech is improved by also coarticulating the recorded speech. The resulting message is smooth, natural sounding and lifelike. Existing libraries of regularly recorded bulk prompts can be used by coarticulating the user interface prompt occurring just before the bulk prompt. Applications include phone-based applications as well as non-phone-based applications.
