Speech Recognition IC HM2007

We are instrumental in offering IC Chip which is a kind of voice recognition circuit in varied specifications. This module comes with an analog front end, recognition process, sound control functions and voice analysis. When combined with microprocessor, these IC chips can be turned into an intelligent recognition system.

The HM2007 Speech Recognition IC performs speech recognition independently in a stand alone mode, or it can function as a slave to a host processor in CPU mode. In stand alone mode, the circuit can recognize up to 40 words lasting one second each.

The chip provides the options of recognizing either forty .96 second words or twenty 1.92 second words. This circuit allows the user to choose either the .96 second word length (40 word vocabulary) or the 1.92 second word length (20 word vocabulary). For memory the circuit uses an 8K X 8 static RAM.

The chip 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.

 

Features of IC Chip are as follows:


  • Single chip voice recognition CMOS LSL.
  • Maximum 40 words can be recognized for one chip.
  • External 64K SRAM can be connected directly.
  • Maximum 1.92 sec of word can be recognized
  • A microphone can be connected directly
  • Speaker- dependent isolates-word recognition system
  • Multiple-chip configuration is possible
  • Two control mode is supported: manual mode & CPU mode.
  • Response time: less than 300ms
  • 5V single power supply
  • 45-pin PDIP, 52 pin PLCC, 48 pad bare chip.

Speech Recognition IC HM2007 KIT

The speech recognition system is a completely assembled and easy to use programmable speech recognition circuit. Programmable, in the sense that you train the words (or vocal utterances) you want the circuit to recognize. This board allows you to experiment with many facets of speech recognition technology. It has 8 bit data out which can be interfaced with any microcontroller for further development. Some of interfacing applications which can be made are controlling home appliances, robotics movements, Speech Assisted technologies, Speech to text translation, and many more.

Features

  • Self-contained stand alone speech recognition circuit
  • User programmable
  • Up to 20 word vocabulary of duration two second each
  • Multi-lingual
  • Non-volatile memory back up with 3V battery onboard. Will keep the speech recognition data in memory even after power off.
  • Easily interfaced to control external circuits & appliances
