Claims
- 1. A ROM circuit for reducing sound data in a voice synthesizing system comprising:
- means for storing a plurality of representative voiceless sound data each representative of a frequency used voiceless speech sound and the memory locations of said representative voiceless sound data being defined by plural byte data start addresses;
- means for memorizing groups of speech sounds collectively defining words of audible speech being designated by a single byte address code;
- address table means for storing said plural byte data start addresses of the representative voiceless sound data in memory locations defined by said single byte address code; and
- means responsive to a said single byte address code for accessing said address table means to select a corresponding one of said plural byte data start addresses to read out said representative voiceless sound data defined thereby.
- 2. A method for reducing memory needed to store sound data in a voice synthesizing system wherein groups of representative sound data indicative of audible speech are memorized and a voice is synthesized therefrom by utilizing the representative sound data, comprising the steps of:
- storing a plurality of representative voiceless sound data, each representative of a frequency used voiceless speech sound and being defined by plural byte data start addresses;
- representing voiceless speech sounds to be synthesized by a single byte address code;
- providing an address table for storing said plural byte data start addresses of the representative voiceless sound data in memory locations defined by corresponding said single byte address code; and
- accessing the representative voiceless sound data through said address table by first accessing said plural byte data start addresses with said single byte address code and then being using plural byte data start addresses to access said representative voiceless sound data.
- 3. A method for reducing memory needed to store sound data in a voice synthesizing system wherein groups of representative sound data indicative of audible speech are memorized and a voice is synthesized therefrom by utilizing the representative sound data, comprising the steps of:
- storing a plularity of representative sound data, each representative of a frequency used speech sound and being defined by plural byte data start addresses;
- representing speech sounds by a single byte address code wherein said speech sounds collectively define words of audible speech to be synthesized;
- providing an address table for storing said plural byte data start addresses of the representative sound data in memory locations defined by corresponding said single byte address code; and
- accessing the representative sound data through said address table by first accessing said plural byte data start addresses with said single byte address code and then using said plural byte data start addresses to access said representative sound data.
- 4. A ROM circuit for recording sound data in a voice synthesizing system, comprising:
- means for storing a plurality of representative sound data each representative of frequently used speech sounds and the memory locations of said representative sound data being defined by plural byte data start addresses;
- means for memorizing groups of speech sounds collectively defining words of audible speech being designated by a single byte address code;
- address table means for storing said plural byte data start addresses of said representative sound data in memory locations defined by said single byte address code; and
- means responsive to said single byte address code for accessing said address table means to select a corresponding one of said plural byte data start addresses to read out said representative sound data defined thereby.
