Abstract
Abstract An electronic apparatus includes a speech synthesizer, a speech synthesis controller, and a microprocessor connected to the speech synthesis controller. The microprocessor controls transmission of sound-related data from the microprocessor to the speech synthesis controller, receives control signals from the sound synthesis controller to said microprocessor and monitors the voltage supplied to the speech synthesis controller. For this purpose the microprocessor is responsive to an output signal indicative of a variation in the voltage for controlling the sound signal delivery operation of the speech synthesis controller.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
123 words
An electronic apparatus comprising: a voltage source; a speech synthesis controller operatively connected to said voltage source; said controller comprising means for generating a first signal for facilitating transfer of data to said controller when said controller receives power from said source at at least a threshold voltage level; data processing means connected to said controller; said data processing means including means for providing data to said controller in response to receipt of said first signal from said controller; said data processing means further comprising means for providing a second signal to said controller for determining the state of said first signal, whereby it is determined whether said voltage source is providing power to said controller at at least said threshold voltage level.
Claim 2
Dependent Claim
123 words
An electronic apparatus comprising: a voltage source; a speech synthesis controller operatively connected to said voltage source; said controller comprising means for generating a first signal for facilitating transfer of data to said controller when said controller receives power from said source at at least a threshold voltage level; data processing means connected to said controller; said data processing means including means for providing data to said controller in response to receipt of said first signal from said controller; said data processing means further comprising means for providing a second signal to said controller for determining the state of said first signal, whereby it is determined whether said voltage source is providing power to said controller at at least said threshold voltage level.
Claim 3
Dependent Claim
14 words
An apparatus as in claim 1 wherein said data processing means comprises a microprocessor.
Claim 4
Dependent Claim
24 words
An apparatus as in claim 1 wherein said speech synthesis controller includes a sound-related data memory and a control memory for storing control instructions.
Claim 5
Dependent Claim
46 words
An apparatus as in claim 1 wherein said means for providing a second signal comprises means for repeatedly providing said second signal to said controller, whereby the state of said first signal and the level of said voltage is determined over an extended period of time.
Claim 6
Dependent Claim
21 words
An apparatus as in claim 2, wherein said speech synthesizer controller and said microprocessor are implemented with a one-chip LSI device.
