About the Switchboard corpus
This is conversational telephone speech collected as 2-channel, 8kHz-sampled
data. We are using just the Switchboard-1 Phase 1 training data.
The catalog number LDC97S62 (Switchboard-1 Release 2) corresponds, we believe,
to what we have. We also use the Mississippi State transcriptions, which
we download separately from
We are using the eval2000 a.k.a. hub5'00 evaluation data. The acoustics are
LDC2002S09 and the text is LDC2002T43.
We are also using the RT'03 test set, available as LDC2007S10. Note: not
all parts of the recipe test with this.
About the Fisher corpus for language modeling
We use Fisher English training speech transcripts for language modeling, if
they are available. The catalog number for part 1 transcripts is LDC2004T19,
and LDC2005T19 for part 2.
Each subdirectory of this directory contains the
scripts for a sequence of experiments.
