Abstract

A speech synthesis device is adapted to provide an audible indication of numerical information through the utilization of a predetermined number of phonemes. Those phonemes are stored within a read only memory on a single large scale integrated circuit chip. A desired length of pause or silence is provided depending upon the kind and location of information to be audibly outputted. The necessity for the pause period is stored in digitally encoded signals within the read only memory in the same manner as with the phonemes.

Claims

1. A synthetic speech device capable of developing audible sounds indicative of numerical data and capable of inserting pause intervals at desired locations within said audible sounds, comprising:

first means for storing said numerical data therein and for storing information indicative of the location of the decimal point within said numerical data;

second means for storing said numerical data therein and developing output signals indicative thereof;

third means interconnected between the first and second means for transferring said numerical data from the first means to the second means;

decision means connected to the first means and third means for determining the digit positions of the numerical data transferred from the first means to the second means relative to the location of the decimal point within said numerical data and developing output signals indicative of the digit positions;

pause code storage means for storing codes indicative of said pause intervals and developing output signals indicative thereof;

control means connected to the pause code storage means, to the decision means, and to the second means and responsive to the output signals delivered therefrom for correlating and synthesizing the numerical data stored in the second means with the digit positions of said numerical data as determined by said decision means, thereby producing a correlated result, said control means retrieving said codes indicative of said pause intervals from said pause code storage means and inserting said pause intervals at certain desired locations within the correlated result, the desired locations being dependent upon the particular correlated result, said control means developing output signals of a predetermined sequential order representative of the correlated result inclusive of the inserted pause intervals; and

means responsive to the output signals from said control means for developing audible sounds in said predetermined sequential order, said audible sounds representing said numerical data, the digit positions of said numerical data, and the pause intervals inserted at said desired locations therein.

2. A synthetic speech device in accordance with claim 1, wherein the digit positions of the numerical data determined by said decision means include the hundred millions position, the ten thousands position, the hundreds position, and the tens position.

3. A synthetic speech device in accordance with claim 2, wherein the correlated result produced by said control means includes the numerical data associated with a particular digit position followed by its associated digit position information,

said control means inserting a said pause interval immediately subsequent to the associated digit position information,

the audible sound developing means developing audible sounds, in sequence, representative of the numerical data associated with the particular digit position, its associated digit position information, and the said pause interval.
