    • A telephone dialing system includes a memory unit for storing a dialed telephone number, a comparator for comparing first digit data of the dialed telephone number stored in the memory unit and second digit data of a telephone number presently being manually dialed and providing a first output when more than half of the digits of the first and second digit data coincide with each other while less than half of the digits of the first and second digit data do not coincide with each other so that the presently dialed number is an incorrectly dialed number and a second output when more than half of the digits of the first and second digit data do not coincide with each other so that the presently dialed number is a new number. An alarm unit issues an alarm in response to the first output. A speech output unit generates a speech output announcing the dialed telephone number stored in the memory unit. A confirmed dialed telephone number sending unit sends out the dialed telephone number announced by the speech output unit in response to a selection input generated by a user via manipulation of a specified special function key. A display unit provides a luminous or flickering display in response to the first output from the comparator unit. A comparative display distinguishably displays the coincidence part and the non-coincidence part of the first and second individual digit data.
    • 电话拨号系统包括用于存储拨打电话号码的存储单元,比较器,用于比较存储在存储单元中的拨号电话号码的第一数字数据和当前正在手动拨打的电话号码的第二数字数据,并提供第一输出, 第一和第二数字数据的多于一半的数字彼此一致,而少于第一和第二数字数据的一半的数字彼此不一致,使得当前拨打的号码是不正确拨打的号码,并且 当第一和第二数字数据的多于一半的数字彼此不一致时,第二输出,使得当前拨打的号码是新的号码。 报警单元响应于第一个输出发出报警。 语音输出单元生成通知存储在存储单元中的拨号电话号码的语音输出。 确认的拨打电话号码发送单元响应于用户经由指定的特殊功能键的操作而生成的选择输入,发出由语音输出单元通知的拨打的电话号码。 显示单元响应于比较器单元的第一输出提供发光或闪烁显示。 比较显示可区分地显示第一和第二单独数位数据的符合部分和非重合部分。
