Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
88 words
A speech synthesizer timepiece capable of providing an audible indication of time information comprising in combination: a timekeeping means for performing a timekeeping operation; a speech synthesizer means for providing an audible indication of the results from said timekeeping means; and a singular key switch means which, upon first actuation, starts a stop watch mode of operation with the development of an audible message and which, upon a second or subsequent actuation, delivers an audible readout of the elapsed time in the form of said preceding audible message.
Claim 2
Dependent Claim

A speech synthesizer timepiece capable of providing an audible indication of time information comprising in combination: a timekeeping means for performing a timekeeping operation; a speech synthesizer means for providing an audible indication of the results from said timekeeping means; and a singular key switch means which, upon first actuation, starts a stop watch mode of operation with the development of an audible message and which, upon a second or subsequent actuation, delivers an audible readout of the elapsed time in the form of said preceding audible message.
Claim 3
Dependent Claim
75 words
The timepiece of claim 1, capable of two operational modes, a first normal mode by which the results of said timekeeping means are cleared when the timekeeping process is temporarily interrupted and the timekeeping operation of said timekeeping means begins from zero and a second accumulation mode by which the results of said timekeeping means are stored unchanged when said timekeeping means operation is temporarily interrupted and said timekeeping operation restarts from said stored results.
