    • An apparatus and method for improving signal to noise ratio of a physiological signal is provided. At least one sensor senses the analog data signal, the analog data signal having a first component including ECG data and a second component including ancillary data. A converter is coupled to the at least one sensor that automatically converts the analog data signal into a digital data signal and decimates the digital data signal from a first sample rate to a second sample rate. A gain compensation circuit is coupled to the converter that automatically measures a magnitude of at least one of the first component and second component of the digital data signal and compares the measured magnitude to a reference value to determine if a gain applied to the analog data signal should be modified and automatically compensates the digital data signal in response to the determination that the analog gain value should be modified, wherein the compensated digital data signal corrects defects associated with a settling period of the converter resulting from modifying the gain applied to the analog data signal.

    • The invention proposes a method and apparatus for significantly improving the quality of voice morphing and guaranteeing the similarity of converted voice. The invention sets several standard speakers in a TTS database, and selects the voices of different standard speakers for speech synthesis according to different roles, wherein the voice of the selected standard speaker is similar to the original role to a certain extent. Then the invention further performs voice morphing on the standard voice similar to the original voice to a certain extent, in order to accurately mimic the voice of the original speaker, so as to make the converted voice closer to the original voice features while guaranteeing the similarity.
    • 本发明提出了一种显着提高语音变形质量并保证转换语音相似性的方法和装置。 本发明在TTS数据库中设置几个标准扬声器,并根据不同的角色选择不同标准扬声器的语音合成语音,其中所选标准扬声器的声音在一定程度上与原始角色相似。 然后本发明在一定程度上进一步对与原始语音相似的标准语音进行声音变形,以便准确地模拟原始扬声器的声音,以便使转换的语音更接近原始语音特征,同时保证相似性 。
