International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: R. Schwartz J. Klovstad J. Makhoul D. Klatt V. Zue Bolt Beranek and Newman 슠Inc. Cambridge MA USA
We report on the synthesis of speech in the context of a phonetic vocoder operating at 100 b/s. With each phoneme, the vocoder transmits the duration and a single pitch value. The synthesizer uses a large inventory of... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: M. Sambur Defense Communications Division ITT Nutley NJ USA
The goal of this study was to develop an effective and computationally inexpensive method of enhancing the linear prediction analysis/synthesis of noisy speech. To this end, a preprocessing filter has been proposed th... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: E. Blackman R. Viswanathan W. Russell J. Makhoul Bolt Beranek and Newman 슠Inc. Cambridge MA USA
Recently we described a variable-frame-rate LPC vocoder designed to transmit good quality speech over 2400 bps fixed-rate noisy channels with bit-error probabilities ranging up to 5% [3]. The basic idea was to lower t... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: R. Preuss MITRE Corporation Bedford MA USA
Performance of narrowband speech communications systems, such as linear predictive coding (LPC), is often severely degraded by the presence of ambient acoustic noise in the input speech signal. Spectral subtraction te... 详细信息
