Functional Description

The Green Voice series is a series of program
mable speech synthesizers and melody genera
tors. It provides various sampling rates and
beats, tone levels, tempos for speech synthe
sizer and melody generator. For voice synthe
sizer, the Green Voice provides 8-bit PCM, 6-bit
m-law PCM and 4-bit ADPCM synthesis. In
HT85XXX series, a mixed output of two chan
nels PCM synthesis is allowed but only one
channel ADPCM synthesis is allowed. For mel
ody generator, the Green Voice supports a tone
melody and PCM melody generator and two
channels mixed output for the whole series.

The Green Voice series build-in 8 programma
ble I/O pins and 4 programmable input pins
along with powerful user¢s command. The
user¢s instructions are employed to develop
new and customized functions for a wide vari
ety of innovative applications.

Speech and melody analysis

The speech and melody sources of the Green
Voice can be recorded and edited from the PC
sound card and media tools. Holtek¢s CAD tools
first load a speech source file as .WAV or .PCM
format, then transfer the speech file as PCM,
LOG-PCM or ADPCM format, and finally save
it to the internal mask ROM by changing a
layer of the mask. The PCM format generates a
higher sound quality whereas the ADPCM for­mat brings about a longer recording capacity.
The melody source can either be in the .MID or
in the .MLD format.

The .MID file is the standard format of the win
dows media tools. The .MLD file is a text for
mat. After the .MID file is compiled, the .MLD
file is automatically generated.

The Green Voice can support the following com
pression format of the voice .WAV and .PCM
file: AD4, PCM8, m-law PCM.

Current type D/A output

-

­The HT85XXX series supply high accuracy cur

rent type D/Aoutput pins for audio output. The

­output volume is changeable from 0 to 15 digi

­tal levels by writing a value to the VOLUME

registers. The D/A pins are PMOS open drain
structure and ouput synthesized signals for

­driving a speaker through an external NPN

transistor when the chip is active. However, it

­becomes floating when the chip is in the

standby state. An 8050 type transistor with
h

=150 is recommended for the output driver

FE

of the D/A output pin.

-

Melody/Tone generator

The HT85XXX family has a built-in mel
ody/tone generator. The generator can generate

­13 different kinds of melody beats, 5 octaves of

tone level, 18 tempos, and 2 channels mixed
output. Of these components, the melody tempo
is changeable and generates sound effects by
writing a control value to the TEMPO register.
The chip provides the following 18 tempos, 13
beats, and 5 octaves for user¢s programming.

PCM/ADPCM synthesizer

The HT85XXX family contains a PCM and
ADPCM synthesizer. The synthesizer offers a
wide range of sampling rates from 4kHz to
24kHz for PCM synthesis and 4kHz to 16kHz
for ADPCM synthesis. The sampling rate of the
synthesizer can be changed by writing a control
value to the sampling rate register. It also sup
ports a small variety of 100Hz. For a higher
performance sound quality, the PCM coding is
required. But for a longer recording capacity,
the ADPCM coding is recommended.

Oscillator configuration

The HT85XXX series provides an RC oscillator
for the system clock. The system oscillator
stops in the standby state so as to reduce power
consumption.

For the oscillator circuit, an external resistor is
required between OSC and VSS. The oscillator
frequency is typically 4MHz for an external re
sistor of 240kW. The RC type of oscillator offers
the most cost-effective solution, although the
frequency of the oscillation may vary with tem
perature and the chip itself due to process vari

­ation.
