Voice synthesis apparaatus and method for synthesizing voice

A voice synthesis apparatus is provided. The voice synthesis apparatus includes: an electrode array configured to, in response to voiceless speeches of a user, detect an electromyogram (EMG) signal from skin of the user; a speech activity detection module configured to detect a voiceless speech period of the user; a feature extractor configured to extract a signal descriptor indicating a feature of the EMG signal for the voiceless speech period; and a voice synthesizer configured to synthesize speeches by using the extracted signal descriptor. 提供了种声音合成设备。该声音合成设备包括：电极阵列，配置为响应于用户的无声语音，从用户的皮肤检测肌电图(EMG)信号；语音活动检测模块，配置为检测用户的无声语音时段；特征提取器，配置为提取指示无声语音时段的EMG信号的特征的信号描述符；和声音合成器，配置为通过使用所提取的信号描述符合成语音。
