    • The speed of an input speech is changed without any change of the pitch of the input speech. Raw data of a speech are stored so that the speed of the speech can be modulated continuously on the basis of the raw data of the speech. In the speech speed conversion method, a speech speed conversion process for the input speech is carried out in a period designated when speech speed conversion is needed, which the speech speed conversion is not carried out in the other period. Further, in the speech speed conversion apparatus having a unit for inputting a speech, a speech speed conversion unit for changing the speed of the input speech, and a unit for supplying the output of the speech speed conversion unit as an output speech to listener's ears, the apparatus further includes a speech speed conversion switch, and a unit for outputting a speech while changing the speech speed of the input speech in a period in which the speech speed conversion switch is turned on, but for outputting a speech without any change of the input speech in the other period in which the speech speed conversion switch is turned off.
    • 改变输入语音的速度,而不改变输入语音的音高。 存储语音的原始数据,使得可以基于语音的原始数据连续地调制语音的速度。 在语音速度转换方法中,在需要语音速度转换时指定的时间段中进行用于输入语音的语音速度转换处理,而在另一个周期中不执行语音速度转换。 此外,在具有用于输入语音的单元的语音速度转换装置中,用于改变输入语音的速度的语音速度转换单元和用于将语音速度转换单元的输出作为输出语音提供给听众的耳朵的单元 该装置还包括语音速度转换开关,以及用于在语音速度转换开关导通的时段中改变输入语音的语音速度而输出语音的单元,但是用于输出语音而不改变语音 在语音速度转换开关关闭的另一周期中的输入语音。

    • A flash type AD converter includes a group of comparators divided into blocks each including 2.sup.N comparators (N=1, 2, ---), each comparing an input signal with one of a plurality of reference signals, each having individually different voltage levels. One of the comparators may correspond to a level change point where the voltage level of the input signal is higher than that of the reference signal of that comparator which then generates a specific output different from those of the remaining comparators. The converter generates a binary-coded output on the basis of the specific output generated from the level change point comparator. When any one of the plural comparators belonging to one of the blocks generates the specific output, the specific output is applied as an inhibit signal to inhibit appearance of an output from a block including comparators having reference voltage signals with corresponding levels lower than those of the comparators of the block to which the comparator generating the specific output belongs.
    • 闪光型AD转换器包括一组比较器,其被分成块,每个块包括2N个比较器(N = 1,2,...),每个比较器将输入信号与多个参考信号中的一个进行比较,每个参考信号具有单独不同的电压电平。 一个比较器可以对应于电平变化点,其中输入信号的电压电平高于该比较器的参考信号的电平,然后产生与剩余的比较器不同的特定输出。 转换器根据从电平变化点比较器产生的特定输出产生二进制编码输出。 当属于其中一个块的多个比较器中的任何一个产生特定输出时,该特定输出被施加作为禁止信号,以抑制来自包括比较器的输出的出现,该比较器具有的参考电压信号的相应电平低于 生成特定输出的比较器所属的块的比较器。

    • Making use of a digital acoustic signal processing apparatus arranged by employing memory device for storing a digital acoustic signal, acoustic frequency feature enhancing device for enhancing an acoustic frequency feature, and low-speed sound reproducing device for changing a speed of the stored voice to reproduce this voice as a low speed into a hearing aid and an appliance with an acoustic output, a hearing function difficulty due to an age is aided in utilization of audio output appliances such as a hearing aid, television receiver, and a telephone receiver. After the voice has been stored in the memory device, a process for enhancing the frequency characteristic in order to fit the frequency characteristic to the individual hearing characteristic and the voice reproducing environment is carried out and thereafter represented to the user. The user can repeatedly listen the voice stored in the memory device with employment of control device for controlling the voice reproducing operation. Furthermore, since a process for expanding a time scale during a sound reproducing operation is carried out, the voice can be represented at the low speed. Since the voice whose frequency characteristic has been enhanced can be represented at the low speed in order that either an individual hearing ability, or an apparatus is fitted to a using environment, hearing articulation can be improved with respect to such a hearing, the frequency resolution and the time resolution are simultaneously deteriorated.
    • 利用通过采用用于存储数字声音信号的存储装置而布置的数字声信号处理装置,用于增强声频特征的声频特征增强装置和用于改变所存储的声音的速度以便再现的低速声音再现装置 这种声音作为低速进入助听器和具有声学输出的器具,由于年龄而引起的听力功能困难有助于使用诸如助听器,电视接收机和电话接收器的音频输出设备。 在语音已被存储在存储装置中之后,执行用于增强频率特性以便将频率特性适应于个人听觉特性和语音再现环境的过程,并且此后表示给用户。 用户可以通过使用用于控制语音再现操作的控制装置来重复监听存储在存储设备中的语音。 此外,由于执行在声音再现操作期间扩展时标的处理,所以可以以低速表示声音。 由于频率特性已被增强的声音可以以低速表示,以便将单独的听觉能力或装置安装在使用环境中,可以相对于这种听觉改善听觉发音,频率分辨率 并且时间分辨率同时恶化。
