Abstract:
System and method for correcting for impulse noise in speech recognition systems. One example system includes a microphone, a speaker, and an electronic processor. The electronic processor is configured to receive an audio signal representing an utterance. The electronic processor is configured to detect, within the utterance, the impulse noise, and, in response, generate an annotated utterance including a timing of the impulse noise. The electronic processor is configured to segment the annotated utterance into silence, voice content, and other content, and, when a length of the other content is greater than or equal to an average word length for the annotated utterance, determine, based on the voice content, an intent portion and an entity portion. The electronic processor is configured to generate a voice prompt based on the timing of the impulse noise and the intent portion and/or the entity portion, and to play the voice prompt.
