Claim 9

A voice synthesizer according to claim 6 wherein said responsive means for transferring phoneme signals to said speech synthesizer includes a buffer means where a group of phoneme signals composing a syllable are stored, and phoneme duration timer means for timing the transfer of phoneme signals from said buffer means to said speech synthesizer.

Claim 10

A voice synthesizer according to claim 7 wherein each actuation of a key of said musical keyboard means causes a group of phoneme code signals making up a syllable to be transferred from said record means to said buffer means.

Claim 11

A voice synthesizer according to claim 8 wherein said phoneme duration timer means includes a memory means in which duration time for each phoneme is stored, counter means set in accordance with the duration time of a phoneme the signal for which has been transferred to said speech synthesizer, clock means for counting down said counter means at a prescribed rate, and trigger means for transferring the succeeding phoneme code to said speech synthesizer and the duration time therefor to said counter means when said counter means is reset to zero.

Claim 12

A voice synthesizer according to claim 9 including means for adjusting said clock means to operate at a different rate.

Claim 13

A voice synthesizer according to claim 10 wherein said pitch control means includes note frequency generator means for generating a frequency signal corresponding to the note played on said musical keyboard means, means for modifying the frequency signal generated by said note frequency generator means, and means for feeding said modified frequency signal to said speech synthesizer so that said phonemes are sounded at a pitch corresponding to said modified signal.

Claim 14

A voice synthesizer according to claim 11 wherein said speech synthesizer includes audio means that produce the audible sounds of said synthesizer, and including means for delivering the frequency signal corresponding to a note directly to said audio means.

Claim 15

A voice synthesizer according to claim 12 including manually operable means for altering the frequency signal generated by said note frequency generator means.

Claim 16

A voice synthesizer according to claim 9 wherein said pitch control means includes note frequency generator means for generating a frequency signal corresponding to the note played on said musical keyboard means, means for modifying the frequency signal generated by said note frequency generator means, and means for feeding said modified frequency signal to said speech synthesizer so that said phonemes are sounded at a pitch corresponding to said modified signal.

Claim 17

A voice synthesizer according to claim 14 wherein said speech synthesizer includes audio means that produce the audible sounds of said synthesizer, and including means for delivering the frequency signal corresponding to a note directly to said audio means.

Claim 18

A voice synthesizer for simulating a voice singing the lyrics of a song comprising: a speech synthesizer for electronically producing spoken words in response to coded signals representing word syllables; record means for storing coded signals representative of the syllables of the words of a song; data keyboard means for entering coded signals representative of the syllables of the words of a song into said record means; musical keyboard means for playing the notes of a melody; and means responsive to said musical keyboard means for transferring coded signals from said record means to said speech synthesizer, said responsive means transferring one coded syllable signal for each musical note played, whereby the tempo of the words produced by said speech synthesizer is controlled by said musical keyboard means.

Claim 19

A voice synthesizer for simulating a voice singing the lyrics of a song comprising: a speech synthesizer for electronically producing spoken words in response to coded signals representing word syllables; record means for storing coded signals representative of the syllables of the words of a song; data keyboard means for entering coded signals representative of the syllables of the words of a song into said record means; musical keyboard means for playing the notes of a melody; and means responsive to said musical keyboard means for transferring coded signals from said record means to said speech synthesizer, said responsive means transferring one coded syllable signal for each musical note played, whereby the tempo of the words produced by said speech synthesizer is controlled by said musical keyboard means.
