+-----------------------------------------------------------------------------
+
+
+OVERVIEW
+
+This is a public domain speech dataset consisting of 13,100 short audio clips
+of a single speaker reading passages from 7 non-fiction books. A transcription
+is provided for each clip. Clips vary in length from 1 to 10 seconds and have
+a total length of approximately 24 hours.
+
+The texts were published between 1884 and 1964, and are in the public domain.
+The audio was recorded in 2016-17 by the LibriVox project and is also in the
+public domain.
+
+
+
+FILE FORMAT
+
+Metadata is provided in metadata.csv. This file consists of one record per
+line, delimited by the pipe character (0x7c). The fields are:
+
+  1. ID: this is the name of the corresponding .wav file
+  2. Transcription: words spoken by the reader (UTF-8)
+  3. Normalized Transcription: transcription with numbers, ordinals, and
+     monetary units expanded into full words (UTF-8).
+
+Each audio file is a single-channel 16-bit PCM WAV with a sample rate of
+22050 Hz.

+MISCELLANEOUS
+
+The audio clips range in length from approximately 1 second to 10 seconds.
+They were segmented automatically based on silences in the recording. Clip
+boundaries generally align with sentence or clause boundaries, but not always.
+
+The text was matched to the audio manually, and a QA pass was done to ensure
+that the text accurately matched the words spoken in the audio.
+
+The original LibriVox recordings were distributed as 128 kbps MP3 files. As a
+result, they may contain artifacts introduced by the MP3 encoding.
+
+The following abbreviations appear in the text. They may be expanded as
+follows:
