Introduction

TalkBank Ethology Corpus: Field Recordings of Vervet Monkey Calls was produced by Linguistic Data Consortium (LDC), catalog number LDC2004S12 and ISBN 1-58563-312-7.

This data publication contains digitized audio files of field recordings of vervet monkeys (cercopithecus aethiops) collected by Robert M. Seyfarth and Dorothy L. Cheney in 1977 and 1978. The original recordings were made on 1/8 inch reel-to-reel tapes, and were digitized at LDC using the sampling frequency of 44.1 kHz. This publication contains downsampled versions of the recordings.

From 2001 through 2004, Dr. Seyfarth and one of his students annotated the recordings for the following fields: start time, end time, type (bout, commentary, etc.), recording date and time, caller ID, recipient ID, context, call type and remarks. This publication contains annotation files that can be viewed with the accompanying software or with spreadsheet software, such as Microsoft Excel.

Data

There are 60 audio files (approximately 5 GB), containing approximately 30 hours of recordings. All of the audio files are in the Microsoft WAV format with the sampling frequency of 22,050 Hz. A sample audio file may be found here.

There are 60 annotation files containing approximately 1,270 annotations of selected audio files in the distributions. All of the annotation files are tab-separated table files without a header, and use the UNIX-style newline (" "). A sample annotation may be found here.
