PROBLEM STATEMENT
The project involves building a system for exchanging voice messages over
mail, using very high speech compression. The sender will record his voice message
and transform it into the coded, compressed file using the encoder module. The coded
file is transferred as an email attachment. The receiver passes the attached file through
the decoder module, which reproduces the original speech. Both the encoder and
decoder will use a repository of speech segments. This repository will be pretty large
in size and may need to be transported by CDs etc.
The entire system (encoder, decoder and repository generator) needs to be
prepared and coded for Linux. The project should deliver a easy-to-use package (it
may be set of command-line tools) which will enable the proposed exchange of voice
messages. The encoder tool should just take a sound file (maybe in the WAV format)
and convert it into a compressed binary file. The decoder tool does the opposite job.
The repository-generator tool works on a large sample of speech to generate the
corpus.
