dsPIC30F Speech Recognition Library

Summary

The dsPIC30F Speech Recognition Library provides voice control

of embedded applications that require an alternative user

interface. With a vocabulary of up to 100 words, the Speech

Recognition Library allows users to control their application

vocally. The Speech Recognition Library is an ideal front end for

hands-free products such as modern appliances, security panels

and cellphones. The Speech Recognition Library has very modest

memory and processing requirements and is targeted for the

dsPIC30F5011, dsPIC30F5013, dsPIC30F6012 and

dsPIC30F6014 processors.

Description

The Speech Recognition Library provides isolated, speaker-

independent word recognition of US English. It allows a user to

control an application through a set of fixed, voice commands.

The library has already been pre-trained by a demographic

cross-section of male and female US English speakers.

Conveniently, no training is required for end-users of the

product.

The library samples speech data from a voice codec connected

to the dsPIC30F's Data Converter Interface. The data is

processed a frame at a time, and when a word ending is

detected, the received word is identified using Hidden Markov

Model processing. After the library identifies the word, your

application may then take some pre-defined action.

The Speech Recognition algorithm is written in assembly

language to optimize performance and minimize RAM usage. A

well defined API makes it easy to integrate the Speech

Recognition Library with your application. Library functions let

your application easily disable and enable speech recognition.

The library lets your other system processing operations take

place without disrupting speech recognition.

A PC-based Word Library Builder program allows you to build a

custom library from a Master Library of 100 common words. A

noise profile is selected that suits your operating environment.

The noise profile consists of a noise type and a signal-to-noise

ratio (SNR). The noise type can be any combination of 3

different noise sources (automobile, office and white noise),

and the SNR may be as low as 15 dB. The Word Library Builder

program generates source files that you then use to build your

application. These files contain data tables that the library

uses to perform speech recognition.
