Enhanced interface for use with speech recognition
First Claim
1. A voice interface method comprising:
- operating a device including a processor to generate an audible user prompt to solicit input from a user, the audible user prompt including words presented using a first rate of speech, andprior to receiving a user response to said user prompt, generating an audible keyword prompt indicating at least some keywords which may be spoken by a user in response to said user prompt, the audible keyword prompt including speech that has at least one feature, including overlapping words, wherein said overlapping words comprise two or more voice keyword prompts that are mixed together to be at least partially overlapped.

Abstract
Improved methods of presenting speech prompts to a user as part of an automated system that employs speech recognition or other voice input are described. The invention improves the user interface by providing in combination with at least one user prompt seeking a voice response, an enhanced user keyword prompt intended to facilitate the user selecting a keyword to speak in response to the user prompt. The enhanced keyword prompts may be the same words as those a user can speak as a reply to the user prompt but presented using a different audio presentation method, e.g., speech rate, audio level, or speaker voice, than used for the user prompt. In some cases, the user keyword prompts are different words from the expected user response keywords, or portions of words, e.g., truncated versions of keywords.

31. A voice interface method comprising:
-
operating a device including a processor to generate an audible user prompt to solicit input from a user, the audible user prompt including words presented using a first rate of speech, and prior to receiving a user response to said user prompt, generating an audible keyword prompt indicating at least one keyword which may be spoken by a user in response to said audible user prompt, the audible keyword prompt including speech that is generated at an audible sound level which is different than an audible sound level at which words in said audible user prompt are generated and at a rate which is different than the first rate of speech.
