Assessment for automatic speech recognition: II. NOISEX-92: A database and an experiment to study the effect of additive noise on speech recognition systems

Abstract The NOISEX-92 experiment and database is described and discussed. NOISEX-92 specifies a carefully controlled experiment on artificially noisy speech data, examining performance for a limited digit recognition task but with a relatively wide range of noises and signal-to-noise ratios. Example recognition results are given.
