Speech recognition is classified into two categories, speaker dependent and speaker independent.
The VR module I used is a SimpleVR module. It supports Speaker Independent (SI) recognition; that means it does not require any speech training and can recognize anyone's voice. The module has a USB port to flash commands using a PC software. The commands are stored in a text file and can be edited with any text editor. This page explains step-by-step how to set up and use Speakable Items, the built-in voice-recognition function in Mac OS X. This provides voice recognition for hands-free control of a computer. However, it is not for speech dictation and lacks the advanced functionality and integration that commercial software can offer. To use voice dictation in an application on your Mac, first select a text field in an application. Next, press the Fn (Function) key twice or click the Edit menu and select Start Dictation. Speak to your Mac and the words you speak will start appearing in the text field. Voice recognition module V3.1– This Tutorial is about the Voice Recognition module v3.1. In this tutorial, you will learn how to train your Recognition module using different languages, you will also learn how to delete a voice command and replace It with another voice command. In this tutorial, we will cover all the basics. Introduction The module could recognize your voice. It receives configuration commands or responds through serial port interface. With this module, we can control the car or other electrical devices by voice. This module can store 15 pieces of voice instruction.
Speaker dependent systems are trained by the individual who will be using the system. These systems are capable of achieving a high command count and better than 95% accuracy for word recognition. The drawback to this approach is that the system only responds accurately only to the individual who trained the system. This is the most common approach employed in software for personal computers.
Speaker independent is a system trained to respond to a word regardless of who speaks. Therefore the system must respond to a large variety of speech patterns, inflections and enunciation's of the target word. The command word count is usually lower than the speaker dependent however high accuracy can still be maintain within processing limits. Industrial requirements more often need speaker independent voice systems, such as the AT&T system used in the telephone systems.
Recognition Style
Speech recognition systems have another constraint concerning the style of speech they can recognize. They are three styles of speech: isolated, connected and continuous.
Isolated speech recognition systems can just handle words that are spoken separately. This is the most common speech recognition systems available today. The user must pause between each word or command spoken. The speech recognition circuit is set up to identify isolated words of .96 second lengths.
Connected is a half way point between isolated word and continuous speech recognition. Allows users to speak multiple words. The HM2007 can be set up to identify words or phrases 1.92 seconds in length. This reduces the word recognition vocabulary number to 20.
Continuous is the natural conversational speech we are use to in everyday life. It is extremely difficult for a recognizer to shift through the text as the word tend to merge together. For instance, 'Hi, how are you doing?' sounds like 'Hi,.howyadoin' Continuous speech recognition systems are on the market and are under continual development.
Speech Recognition Circuit
The demonstration circuit operates in the HM2007's manual mode. This mode uses a simple keypad and digital display to communicate with and program the HM2007 chip.
Keypad: The keypad is made up of 12 switches.
When the circuit is turned on, the HM2007 checks the static RAM. If everything checks out the board displays '00' on the digital display and lights the red LED (READY). It is in the 'Ready' waiting for a command.
To Train
To train the circuit begin by pressing the word number you want to train on the keypad. The circuit can be trained to recognize up to 40 words. Use any numbers between 1 and 40. For example press the number '1' to train word number 1. When you press the number(s) on the keypad the red led will turn off. The number is displayed on the digital display. Next press the '#' key for train. When the '#' key is pressed it signals the chip to listen for a training word and the red led turns back on. Now speak the word you want the circuit to recognize into the microphone clearly. The LED should blink off momentarily, this is a signal that the word has been accepted.

Continue training new words in the circuit using the procedure outlined above. Press the '2' key then '#' key to train the second word and so on. The circuit will accept up to forty words. You do not have to enter 40 words into memory to use the circuit. If you want you can use as many word spaces as you want.
Testing Recognition
The circuit is continually listening. Repeat a trained word into the microphone. The number of the word should be displayed on the digital display. For instance if the word 'directory' was trained as word number 25. Saying the word 'directory' into the microphone will cause the number 25 to be displayed.
Error Codes

The chip provides the following error codes:
55 = word too long
66 = word too short
77 = word no match
