Abstract
This paper explores data embedding in G.711 mu-law speech signals with the spread spectrum techniques. Based on an optimized spread spectrum scheme, a simple but effective solution is presented for high-capacity embedding. Simulations show that the proposed scheme, when incorporated with the measure of the frequency masking effects, can achieve an embedding rate of about 100 bits per second with a 7% bit error rate (BER), or 1000 bps with a 10% BER
