Boll, Steven F. | Application of the saber method for improved spectral analysis of noisy speech | A stand alone noise suppression algorithm is described for reducing the spectral effects of acoustically added noise in speech. A fundamental result is developed which shows that the spectral magnitude of speech plus noise can be effectively approximated as the sum of magnitudes of speech and noise.... | Noise suppression algorithm; SABER method | 1977 |

Boll, Steven F. | Selected methods for improving synthesis speech quality using linear predictive coding: system description, coefficient smoothing and streak | This report develops two generalizations of the standard Linear Predictive Coding (LPC) implementation of a narrow band speech compression system. The purpose of each method is to improve the speech quality that is available from a standard LPC system. | Linear Predictive Coding; LPC; Speech compression system; Pitch excited system | 1974 |

Boll, Steven F. | Suppression of acoustic noise in speech using two microphone adaptive noise cancellation | Acoustic noise with energy greater or equal to the speech is suppressed by filtering a separately recorded correlated noise signal and subtracting it from the speech waveform. This approach was investigated to determine the degree of noise suppression possible using an external correlated input. The... | Suppression; acoustic noise; adaptive noise cancellation | 1979 |
