Abstract
Abstract A synthesizer is disclosed which has the function of generating synthesized human voices and melodies in the form of synthesized sounds. The speech synthesizer may be implemented with one or more LSI devices which include a central processor unit for receiving word codes or melody program codes and for controlling the synthesizer, a memory for storing the sequence of synthesis for each word and melody, a synthesized word generator for providing audible indications of the respective words in the form of a synthesized sound and a melody generator for providing melodies in the form of a synthesized sound. A decision circuit decides if word codes or melody programs are provided. The selected words are audibly delivered by fetching its associated sequence of synthesis from the memory and synthesizing those words through the synthesized word generator or the selected melodies are audibly delivered by fetching its associated sequence of synthesis from the memory and synthesizing the selected melodies through the melody generator.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
153 words
A synthesizer comprising: central processor means for receiving word codes or melody program codes and for outputting signals controlling said synthesizer; memory means for storing data representing sequences of sound synthesis for each of a plurality of words and melodies which may be synthesized by said synthesizer; word generator means for providing audible indications of words in the form of synthesized sounds; and melody generator means for providing audible indications of melodies in the form of synthesized sounds, means responsive to said central processor means for fetching first data representing the sequence of sound synthesis of at least one word from said memory means and for providing said first data to said word generator means; and means responsive to said central processor means for fetching second data representing the sequence of sound synthesis of at least one melody from said memory means and for providing said second data to said melody generator means.
Claim 2
Dependent Claim
153 words
A synthesizer comprising: central processor means for receiving word codes or melody program codes and for outputting signals controlling said synthesizer; memory means for storing data representing sequences of sound synthesis for each of a plurality of words and melodies which may be synthesized by said synthesizer; word generator means for providing audible indications of words in the form of synthesized sounds; and melody generator means for providing audible indications of melodies in the form of synthesized sounds, means responsive to said central processor means for fetching first data representing the sequence of sound synthesis of at least one word from said memory means and for providing said first data to said word generator means; and means responsive to said central processor means for fetching second data representing the sequence of sound synthesis of at least one melody from said memory means and for providing said second data to said melody generator means.
Claim 3
Dependent Claim
193 words
A synthesizer comprising: central processor means for receiving word codes or melody program codes and for outputting signals controlling said synthesizer; decision means for deciding whether said central processor means outputs signals indicating that it has received word codes or melody program codes; memory means for storing data representing sequences of sound synthesis for each of a plurality of words and melodies which may be synthesized by said synthesizer; word generator means for providing audible indications of words in the form of synthesized sounds; and melody generator means for providing audible indications of melodies in the form of synthesized sounds, said word generator means and said melody generator means being alternately and selectively responsive to output of said decision means; means responsive to said decision means for fetching first data representing the sequence of sound synthesis of at least one word from said memory means and for providing said first data to said word generator means; and means responsive to said decision means for fetching second data representing the sequence of sound synthesis of at least one melody from said memory means and for providing said second data to said melody generator means.
Claim 4
Dependent Claim
193 words
A synthesizer comprising: central processor means for receiving word codes or melody program codes and for outputting signals controlling said synthesizer; decision means for deciding whether said central processor means outputs signals indicating that it has received word codes or melody program codes; memory means for storing data representing sequences of sound synthesis for each of a plurality of words and melodies which may be synthesized by said synthesizer; word generator means for providing audible indications of words in the form of synthesized sounds; and melody generator means for providing audible indications of melodies in the form of synthesized sounds, said word generator means and said melody generator means being alternately and selectively responsive to output of said decision means; means responsive to said decision means for fetching first data representing the sequence of sound synthesis of at least one word from said memory means and for providing said first data to said word generator means; and means responsive to said decision means for fetching second data representing the sequence of sound synthesis of at least one melody from said memory means and for providing said second data to said melody generator means.
Claim 5
Dependent Claim
21 words
A synthesizer as defined in claim 1 wherein said memory means stores pitch data and duration data for generation of melodies.
Claim 6
Dependent Claim
26 words
A synthesizer as defined in claim 3 wherein said melody generator means further includes an envelope memory for providing a proper envelope for the pitch data.
Claim 7
Dependent Claim
22 words
A synthesizer as defined in claim 1 wherein said word generator means and said melody generator means are independent of each other.
Claim 8
Dependent Claim
21 words
A synthesizer as in claim 2, wherein said word generator means and said melody generator means are independent of each other.
