What is Speech Recognition in Noisy Cars about?

The document discusses speech recognition accuracy in automobiles. It analyzes the effects of different noise sources on recognition accuracy, including engine noise, wind noise, radio noise, and windshield wiper noise. It finds that radio talk shows cause the greatest degradation in accuracy. The use of cepstral mean normalization and codeword-dependent cepstral normalization techniques significantly improve recognition accuracy in most conditions, except when radio talk shows are playing at low car speeds
