Converter 100 uses either the output signal of a sound pickup device or the signal obtained by subtracting the output signal of an echo canceller from the output signal of the sound pickup device as a first signal, uses an estimated crosstalk value indicative of an estimated value of the amount of crosstalk of an echo leaking into the first signal to correct the first signal, and limits the corrected first signal not to be smaller than estimated near-end noise. |
