Notes:
1. The Duration1 is calculated based on 6000Hz*4-bits = 24 Kbps, 24 Kbps on the assumption that all the ROM space is used
to store speech data.
2. The Duration2 is calculated based on 8000Hz*4-bits = 32 Kbps, 32 Kbps on the assumption that all the ROM space is used
to store speech data.
3. "In" is the number of input pins; "Bid" is the number of I/O pins.
4. Synthesized speech in ADPCM/MDPCM format.
