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.

Application
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.
