Abstract

Computer-implemented methods for training an acoustic model for a far-field utterance processing system are provided. The acoustic model may be configured to map an input audio signal into linguistic or paralinguistic units. The training may involve imparting far-field acoustic characteristics upon near-field training vectors that include a plurality of near-microphone utterance signals. Imparting the far-field acoustic characteristics may involve generating a plurality of simulated room impulse responses, convolving one or more of the simulated room impulse responses with the near-field training vectors, to produce a plurality of simulated far-field utterance signals and saving the results of the training in one or more non-transitory memory devices corresponding with the acoustic model. Generating simulated room impulse responses may involve simulating room reverberation times but not simulating early reflections from room surfaces.
