A system for recognizing mental states of babies is proposed from the frequency analyses of their cries. In the previous research, the researchers clarified that the babies' cries can be classified into hungry ones and sleepy ones by the frequency analyses, if the babies are elder than or equal to 5 months old. Since the frequency distribution of cries differs depending on their month age, the same method for classification cannot be applied to the cries of younger babies, under 5 months old.In this research, another difference was found in the frequency distribution of hungry cries and sleepy ones for babies aged from 3 to 4months old. Crying voices were collected from 16 babies, both male and female, and the rough forms of the amplitude spectra were examined. For hungry cries, one of the following tendencies was observed.1)The spectrum falls steeply around 6kHz.2)The spectrum keeps a high value till about 8-9kHz and falls gradually.3)The spectrum falls gradually from 0 kHz and takes … More a convex form upward.Otherwise, babies were often in a sleepy state. Using these tendencies, a rule-based system which classifies a hungry state and a sleepy one was proposed for babies aged from 3 to 4 months old. About 80% of the cries of the 16 babies were correctly classified into hungry and sleepy states with this system. Some classification results are judged as mistakes, because babies are sometimes in both hungry and sleepy states and it is difficult to obtain the true reason for the cry. Also the correct classification rate depends on babies a little. The system was shown to be valid for most of the 16 babies, but not for one of them.Since noise reduction of the babies' cries is necessary for this research, a nonlinear digital filter for noise reduction of speech signal was proposed by the head investigator before. New research on the application of this nonlinear digital filter to noise reduction of image and the detection of watermark signal in digital cinema was also performed. Less

本文提出了一种从婴儿哭声的频率分析中识别婴儿心理状态的系统。在之前的研究中，研究人员阐明，如果婴儿大于或等于5个月，则可以通过频率分析将婴儿的哭声分为饥饿的哭声和困倦的哭声。由于不同月龄婴儿的哭声频率分布不同，同样的分类方法不能适用于5个月以下的婴儿的哭声。在这项研究中，发现3至4个月婴儿的饥饿哭声和困倦哭声频率分布的另一个差异。从16个婴儿，男性和女性的哭声收集，和振幅谱的粗略形式进行了检查。对于饥饿的叫声，有以下趋势之一：1）频谱在6 kHz附近急剧福尔斯; 2）频谱在8- 9 kHz附近保持高值，然后逐渐福尔斯; 3）频谱从0 kHz开始逐渐福尔斯， ...更多信息 一个向上凸起的形状。否则，婴儿往往处于困倦状态。利用这些趋势，提出了一个基于规则的系统，该系统对3至4个月大的婴儿进行饥饿状态和困倦状态的分类。16个婴儿的哭声中，约有80%被正确地分为饥饿和困倦状态。有些分类结果被判断为错误，因为婴儿有时处于饥饿和困倦状态，很难获得哭泣的真正原因。正确的分类率也取决于婴儿一点点。该系统对16个婴儿中的大多数有效，但对其中一个无效。由于婴儿哭声的降噪是本研究所必需的，因此首席研究员之前提出了一种用于语音信号降噪的非线性数字滤波器。对该非线性数字滤波器在数字电影图像降噪和水印信号检测中的应用进行了新的研究。少
