Abstract
With advancements in technology, automation is paving the way for many manual methods in industry and daily life. Voice control and synthesis are an important part of automation. Direct Digital Synthesis (DDS) is a technology for the digital generation of human-like speech. DDS can create arbitrary waveforms using a single-frequency clock source. The amplitude value of the waveform is stored in the memory. With DDS signals can be generated directly from the values stored in the memory. Different frequencies can be produced by using the sine, and cosine look-up tables i.e. by varying the phase values. Machine voice is a fascinating field for the application of DDS. IVRS (Interactive Voice Response System) is used in many fields of life. Currently, the voice is generated by using analog means. The voice of a person is recorded for all possible phrases and replayed by computer control. The voice can be generated by digital means also especially customer care, announcements at public places, etc.
