ECHNOLOGY
The SC-6x product family introduces a new world of speech synthesis
opportunities. This family is built around a 12.32 million instructions per
second (MIPS) Digital Signal Processor (DSP) to enable advanced speech
algorithms, yielding speech quality never before obtained at such low data
rates.
These DSPs provide three low-power modes, two timer interrupts, one DAC
interrupt and five general-purpose interrupts. These features increase battery life
and speed of response to button and keyboard presses.
Sensory SC-6x employs three processing methods - CX, MX, LPC - that produce natural sounding
speech while using a relatively small amount of memory. Your product’s quality will speak for itself.
If your product needs music, Sensory offers several choices, including simultaneous speech with high
quality polyphonic music.

synthesis is your solution for producing long durations of great speech and sound
effects at the lowest possible system cost. MX offers data rates as low as 1K bits-per-
3.0~11.2 22.5~84.0
second, yielding high quality speech with minimal development effort.
CX

synthesis provides optimal speech and sound effects. Its highly sophisticated analysis
can reproduce the subtle qualities of a broad range of character voices. CX offers up to six
choices of data rates to help you optimize speech quality and memory cost.

LPC
is mathematically simpler than MX or CX, requiring less processing power but more
editing.
Music Synthesis
Sensory also provides a way to enhance your products with high quality music synthesis.
Sensory’s music synthesizer provides polyphonic music using standard Musical Instrument Digital Interface (MIDI)
files that have been converted into compact bitstreams. This gives the ability to play up to 14 channels of music.
Music + Speech
The music synthesizer can also play polyphonic music simultaneously with speech (MX or CX),
adding even more excitement to your products.

SC-601
The SC-601 has a 1.5 Mb ROM to
support up to 24 minutes of internally-
stored MX speech or up to 8 minutes
of CX speech.
SC-604
The SC-604 contains the same
powerful core, ROM and RAM as the
other SC-6xx devices, but has a
reduced I/O set and pin count which
makes it the most economical of the
SC-6x family members.
SC-605
The SC-605 has a 2.36 Mb (288 KB)
ROM to support up to 37 minutes of
internally-stored MX speech or up to
12 minutes of CX speech. This device
is a perfect one-chip system solution,
functioning as master controller,
speech processor, and data memory.
SC-614
The SC-614 expands the capability of
the SC-6x family by incorporating 64
I/O pins for interfacing with the outside
world. It can also address up to 64 Mb
of external memory, providing over
18
hours of speech duration!

SC-691
The SC-691 is a pre-programmed
slave synthesizer implemented on the SC-6xx family line that accepts commands and compressed
speech data from other microprocessors or microcontrollers and converts it to speech output. Since no
SC-6x programming knowledge is needed, this is the simplest SC-6x family member to develop with.

OOLS
Along with a complete line of speech products, Sensory
offers tools for code development and speech editing.
The software development process and speech editing
can take place simultaneously, reducing product
development time and gets your product to market
faster.
When software development and speech editing are
complete, a speech emulation system lets you verify that
everything sounds great before going into production.
