SC-6X FAMILY
SPEECH AND MUSIC PROCESSORS
Whether you need your product to say a few words or talk for several minutes, Sensory’s SC-6x speech
and music processors can deliver a few seconds to several hours of speech.
Every Sensory speech product is made with your design in mind. Efficient technology allows you to cut
costs and size by using smaller and fewer devices. A complete range of development tools and
software helps you get your products to market faster.
POWERFUL TECHNOLOGY
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.
A RANGE OF CHOICES
Not only can you choose the optimum combination of price and capacity, you can adopt any of these
digital storage alternatives: On-chip mask programmable ROM, External memory (SC-614 only).
TYPES OF SYNTHESIS
Memory Required per Minute of Speech (KB)
Data Rate Kbps
CX 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-
second, yielding high quality speech with minimal development effort.
MX 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.
