In recent years, IP telephone use has spread rapidly thanks to the development of VoIP (Voice over
IP) technology. However, an unavoidable problem of the IP telephone is deterioration of speech due to packet
loss, which often occurs on the wireless network. To overcome this problem, we propose a novel packet loss concealment
algorithm using speech recognition and synthesis. This proposed method uses linguistic information
and can deal with the lack of syllable units which conventional methods are unable to handle. We conducted
subjective and objective evaluation experiments. These results showed the effectiveness of the proposed method.
Although there is a processing delay in the proposed method, we believe that this method will open up new
applications for speech recognition and speech synthesis technology.
