语音报时(Repeater) 原是为盲人或无光源而设计的时钟或手表。在机械表方面，分为二问和三问，为其报时方式为按下问时掣，表便可针对时、刻及、分(二问表只报时刻)发出不同音阶声响报时。例如二点十七分则发出高音两响(时)，次高音一响(刻)，高音两响(分)，在不能目视的环境下，便可得知时间，为复杂功能，价格非常昂贵。

而语音报时的电子表相对的很便宣，其透过语音合成的方式，只要按下按钮，便能以不同的语言将时间读出。

A repeater is a complication in a mechanical watch or clock that audibly chimes the hours and often minutes at the press of a button. There are many types of repeater, from the simple repeater which merely strikes the number of hours, to the minute repeater which chimes the time down to the minute, using separate tones for hours, quarter hours, and minutes. They originated before widespread artificial illumination, to allow the time to be determined in the dark, and were also used by the visually impaired. Now they are mostly valued as expensive novelties by watch and clock enthusiasts. Repeaters should not be confused with striking clocks or watches, which do not strike on demand, but merely at regular intervals.
