Abstract
Methods and apparatus for providing speech recognition in noisy environments. An energy level associated with audio input is ascertained, and a decision is rendered on whether to accept the at least one word as valid speech input, based on the ascertained energy level.
Claims13
A method of providing speech recognition in noisy environments, said method comprising the steps of:
- accepting audio input;
- determining at least one word associated with the audio input;
- ascertaining an energy level associated with the audio input;
- normalizing the ascertained energy level;
- ascertaining a detailed match score associated with the at least one word;
- and
- rendering a decision on whether to accept the at least one word as valid speech input, based on the normalized energy level and match score.
An apparatus for providing speech recognition in noisy environments, said apparatus comprising:
- an input medium which accepts audio input;
- an arrangement which determines at least one word associated with the audio input;
- an arrangement which ascertains an energy level associated with the audio input;
- an arrangement which norrmalizes the ascertained energy level;
- an arrangement which ascertains a detailed match score associated with the at least one word;
- and
- a decision arrangement which renders a decision on whether to accept the at least one word as valid speech input, based on the normalized energy level and match score.
A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform method steps for providing speech recognition in noisy environments, said method comprising the steps of:
- accepting audio input;
- determining at least one word associated with the audio input;
- ascertaining an energy level associated with the audio input;
- ascertaining an energy level associated with the audio input;
- normalizing the ascertained energy level;
- ascertaining a detailed match score associated with the at least one word;
- and
- rendering a decision on whether to accept the at least one word as valid speech input, based on the normalized energy level and match score.
