| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Pulse Code Modulation is a basic speech coding for speech transmission and recordings. In PCM, quantization noises increase according to the decrease of the number of quantization bits, and the noisiness of the speech degrades hearing performances. Although the quantization noises can be decreased by allocating larger number of bits, the amount of coded speech data become larger. In this paper, we investigate a system which decreases the quantization noises at low bit rate quantization. An example database approach is applied to replace noisy input speech with clean speech in the database. | |
