A speech synthesizer that utilizes Complementary Metal-Oxide-Semiconductor (CMOS) technology is a device capable of converting text into audible speech. This type of synthesizer employs CMOS circuits to generate sound waves, allowing it to produce a wide range of frequencies and pitches. The use of CMOS technology enables the synthesizer to operate with low power consumption, making it suitable for portable devices. By leveraging the precision and efficiency of CMOS circuits, this speech synthesizer can efficiently convert digital information into spoken language.
