Description: The HM2007 is a CMOS voice recognition LSI (Large Scale Integration) circuit. The chip contains an analog front end, voice analysis, regulation, and system control functions.  The chip provides the options of recognizing either the .96 second word length (40 word vocabulary) or the 1.92 second word length (20 word vocabulary). A 40 isolated-word voice recognition system can be composed of external microphone, keyboard, 64K SRAM  and some other components. Combined with microprocessor, an intelligent system can be built.

   The HM2007 Speech Recognition IC has two operational modes; manual mode and CPU mode. The CPU mode is designed to allow the chip to work under a host computer. This is an attractive approach to speech recognition for computers because the speech recognition chip operates as a co-processor to the main CPU. The jobs of listening and recognition doesn't occupying any of the computer's CPU time. When the HM2007 recognizes a command it can signal an interrupt to the host CPU and then relay the command code. The HM2007 chip can be cascaded to provide a larger word recognition library.

  • Single chip voice recognition CMOS LSI.
  • Speaker dependent isolates- word recognition system.
  • External 64K SRAM can be connected directly.
  • Maximum 40 words can be recognized for one chip.
  • Maximum 1.92 sec of word can be recognized.
  • Multi-chip configuration is possible.
  • A microphone can be connected directly.
  • Two control mode is supported: manual mode and CPU mode.
  • Response Time: Less than 300ms.
  • 5V single Power Supply.
  • 48 pin PDIP, 52 pin PLCC, 48 pad bare chip.

Package includes:

  • 1 x HM2007 - Speech Recognition IC
