Correction of the Voice Timbre Distortions on Telephone Network

In a telephone link, the voice timbre is affected by the loss of low frequencies components and distortions due to the analog lines. We analyze first how the quantization noise limits the restoration of the timbre. Within this limitation, a method of equalization, inspired by the cepstral subtraction, is then proposed to correct the timbre and is validated by experimental results.
