SC-6x Slave Processor
 

The SC-6x slave processor features high-quality low data-rate speech compression.

From talking toys to security systems, products that include Sensory's cost-effective speech solutions stand out because they speak out.

Whether you need your product to say a few words or talk for several minutes, Sensory's speech processors can deliver a few seconds to several hours of speech.

Types of Synthesis

  • MX 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.
  • 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.
  • LX Synthesis is a simpler version of CX synthesis that is more suitable for timing critical and RAM usage sensitive projects.
  • LPC Synthesis is mathematically simpler than MX or CX, requiring less processing power but more editing.
 
 
Method Data Rate Kbps Memory Required per Minute of Speech
CX  3.0 - 11.2 22.5 - 84.0 Kbytes
MX  1.0 - 3.5 7.5 - 26.2 Kbytes
LPC-10  1.8 13.5 Kbytes
 
 
SC-6x Slave Processors

The SC-6x slave processor introduces a new world of speech synthesis opportunities. This chip 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.

The advanced Sensory speech algorithms supported by this product family provide:

  • Long Duration Speech
    1K bit-per-second MX provides the capability to store large amounts of high quality speech with unheard-of economy in memory requirements.
  • High-Quality, Economical Bit Rate
    3K bit-per-second CX supports those applications where a very economical bit rate is needed.
  • Multiple Options to Mix and Match
    Five other fixed bit rates of CX and a variable range of MX bit rates are available which you can mix-and match seamlessly to optimize quality and memory requirements.

Product Specifications
SC-691
The SC-691 is a preprogrammed 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.
