GENERAL DESCRIPTION
The RC8650 is a highly versatile voice and sound synthesizer, integrat-
ing a text-to-speech (TTS) processor, real time and prerecorded audio
playback, musical and sinusoidal tone generators, telephone dialer
and A/D converter, into an easy to use chipset. Using a standard serial
or eight bit bus interface, virtually any ASCII text can be streamed to
the RC8650 for automatic conversion into speech by the TTS proces-
sor. The audio playback modes augment the TTS processor for ap-
plications requiring very high voice quality and a relatively small, fixed
vocabulary, or applications requiring special sounds or sound effects.
The audio output is delivered in both analog and digital PCM audio for-
mats, which can be used to drive a speaker or digital audio stream.
The RC8650’s integrated TTS processor incorporates RC Systems’
DoubleTalk TTS technology, which is based on a patented voice
concatenation technique using real human voice samples. The Dou-
bleTalk TTS processor also gives the user unprecedented real-time
control of the speech signal, including pitch, volume, tone, speed,
expression, articulation, and so on.
Up to 3.5 MB of nonvolatile memory is included in the RC8650 for the
storage and on-demand playback of up to 15 minutes of prerecorded
messages and sound effects. A programmable “greeting” message
can be stored that is automatically played whenever the RC8650 is
powered up, allowing a custom message to be played or the RC8650’s
default settings to be reconfigured. A user-programmable dictionary
allows the pronunciation of virtually any character string to be rede-
fined, or even trigger the playback of tones, prerecorded messages
and sounds based on specific input patterns. All of these features can
be programmed and updated via a standard serial port, even in the
field after the RC8650 has been integrated into the end-product.
The RC8650 is comprised of two surface-mounted devices. Both oper-
ate from a +3.3 V or +5 V supply and consume very little power. Most
applications require only the addition of a lowpass filter/audio power
amplifier to implement a fully functional system.
