This directory contains the Census (AN4) database audio files. Some files from the original database were excluded, namely those with filenames starting with "cen9".
The AN4 database was recorded at Carnegie Mellon University circa 1991. For more detailes, please see "Acoustical and environmental robustness in automatic speech recognition", by Alex Acero, published by Kluwer Academic Publishers, 1993.
The files have been converted to RIFF (a.k.a. Microsoft WAV) format for ease of use.
The directories contain:
-wav/an4_clstk: training data set recorded on close talking microphone.
-wav/an4test_clstk: test data set recorded on close talking microphone.
-etc: directory containing the transcriptions, control files, dictionaries, and a basic unigram language model for evaluation.
This database is mostly interesting for quickly testing the training scripts, as it is quite small and simplistic.
To run basic training:
docker run -t dhdaines/sphinxtrain -t an4 setup
docker run -v $PWD:/st -t dhdaines/sphinxtrain run
