The data to be used in this lab is the TIDIGITS corpus, a standard ASR data set consisting of clean recordings of about 300 speakers reading digit sequences. In this lab, we are doing isolated digit recognition, so we will use only the utterances consisting of a single digit: each speaker was required to say each of the 11 digits (one through nine, zero, and oh) by itself two times.
For this part of the exercise, just listen to a few samples of the data. Here is one sample for each digit; click on the links to listen to each sample: [Sample 1], [Sample 2], [Sample 3], [Sample 4], [Sample 5], [Sample 6], [Sample 7], [Sample 8], [Sample 9], [Sample 10], and [Sample 11].
