It contains a speech processor chip (SPC) and speech ROM and when used with external filter amplifier. and speaker produces a system which generates high quality speech. Male female and children s voices can be synthesized.The SPC communicates with the speech ROM which contains the compressed speech data as well as the frequency and amplitude data required for speech output. Up to 128k bits of speech data can be directly accessed.With the addition of an external resistor on-chip debounce is provided for use with a switch interface.An interrupt is generated at the end of each speech sequence so that several sequences of words can be cascaded to form different speech expressions.The DT1050 is a standard DIGITALKER kit encoded with 137 separate and useful words 2 tones and 5 different silence durations. (See the Master Word List Table 1). The words and tones have been assigned discrete addresses making it possible to output single words or words concatenated into phrases or even sentences.The voice output of the DT1050 is a highly intelligible male voice. The vocabulary is chosen so that is is applicable to many products and markets.National does not assume any responsibility for use of any circuitry described. No circuit patent licenses are implied and National reserves the right at any time without notice to change said circuitry.
