SPEAKING SPEED CONVERTING DEVICE AND SPEAKING SPEED CONVERTING METHOD

摘要

A speaking speed converting device capable of improving intelligibility by performing speaking speed conversion in consideration of surrounding noise. In this device, a microphone (101) collects voice when the user of a communication device (100) makes conversation. A noise power detecting section (102) detects the noise level of noise included in the voice data of the collected voice or the noise level of noise included in voice data transmitted from a communication party. A speaking speed control unit (103) performs a control of converting the speaking speed on the basis of the noise level. A silence detecting section (105) detects a silence portion. A buffer (106) temporarily stores the voice data. A speaking speed conversion circuit (107) performs a processing for changing the speaking speed to the voice data read out from the buffer (106) according to the control of the speaking speed control unit (103).
