Abstract

A method for intelligent speech recognition for premature enunciators is disclosed. The method allows for speech recognition systems to adjust to commands of premature enunciators, who speak before the system is ready receive speech input. The method comprises activating the speech recognition system, informing the user that the speech recognition system is ready to receive speech input, and initiating a listening period. The method further comprises receiving input from a user before the system is ready to receive such input, identifying the user as a premature enunciator, and adjusting the system to allow for earlier detection of user speech input.

Claims

1. A method for a speech recognition system to adjust to premature enunciator commands, the method comprising:

activating the speech recognition system;

receiving speech input from a user before the system is ready to receive speech input;

determining that the user has spoken prematurely; and

adjusting the system after determining that the user has spoken prematurely to allow for earlier detection of user speech input;

wherein the method further comprises the speech recognition system providing a prompt indicating that the system is ready to receive speech input, receiving the user speech input before the system has started a first listening period that begins after a delay following the prompt, and thereafter providing a subsequent prompt and starting a subsequent listening period at an earlier time relative to its prompt.
