First Claim
Patent Images
1. A speech synthesizer device comprising:
- synthesizing means for providing a sound synthesis waveform signal in response to an input signal applied thereto;
instructing means for providing an interruption instruction when speech synthesis by said synthesizer device is to be interrupted;
means for determining the level of the waveform signal; and
interrupting means responsive to said determining means and operatively connected to said synthesizing means for interrupting said synthesizing means in response to the instruction from said instructing means when the waveform signal is at a relatively low amplitude level.

Abstract
A noise-free speech synthesizer is disclosed which interrupts an audible output of synthesized sounds during the period of time where a sound waveform signal is at a relatively low level (amplitude), that is, a voiceless interval, a silent interval or a pitch control interval, wherein a reference level is established for the purpose of controlling pitch. Such low-level cut-off avoids the harsh click of sound cut-off.
