GENERAL DESCRIPTION:
The AVH308 , AV0708 , AV1408 and AV2108 are single-chip voice synthesizing CMOS IC. They are low cost with proper functions and can synthesize voice up to 3.5, 7, 14 and 21 seconds, using Aplus 4-bit LOGPCM algorithm. Customer speech data can be programmed into ROM by changing one mask during the device fabrication. Besides, not only a very flexible functions I/O pin is available for the user to apply in various applications, but also an interactive development tool “EzSpeech” is ready for user-friendly programming.
