Voice Synthesizer Chipset

GeneRal DeSCRipTiOn

The RC8660 is a versatile voice and sound synthesizer, integrating a

text-to-speech (TTS) processor, audio recording and 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 RC8660 for

automatic conversion into speech by the TTS processor. The audio re-

cord and playback modes augment the TTS processor for applications

requiring very high voice quality and a relatively small, fixed vocabulary,

applications requiring special sounds or sound effects, and/or the re-

cording of voice memos. The audio output is delivered in both analog

and digital PCM audio formats, which can be used to drive a speaker

or digital audio stream.

The RC8660’s integrated TTS processor incorporates RC Systems’

DoubleTalk™ TTS technology, which is based on a unique voice con-

catenation technique using real human voice samples. The DoubleTalk

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 RC8660 for the

storage of up to 15 minutes of recorded messages and sound effects. A

programmable “greeting” message can be stored that is automatically

played whenever the RC8660 is powered up, allowing a custom mes-

sage to be played or the RC8660’s default settings to be reconfigured.

A user-programmable dictionary allows the pronunciation of virtually

any character string to be redefined, or even trigger the playback of

tones, pre-recorded 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 RC8660 has been inte-

grated into the end-product.

The RC8660 is comprised of two surface-mounted devices. Both op-

erate 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.
