dsPIC30F Speech Recognition Library
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 applications vocally. The Speech
Recognition Library is an ideal front-end for hands-free
products, such as modern appliances, security panels
and cell phones. The Speech Recognition Library has
very modest memory and processing requirements.

The Speech Recognition Library provides isolated,
speaker-independent word recognition of US English. It
allows the 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.
