Usage

s=sig_competingtalkers(signame);
[s,fs]=sig_competingtalkers(signame);

sig_competingtalkers(signame) loads one of several test signals consisting of competing talkers. All the talkers are taken from the TIMIT speech corpus: http://www.ldc.upenn.edu/Catalog/CatalogEntry.jsp?catalogId=LDC93S1.

The signals have 2 channels and are all recorded with a sampling rate of 16 kHz.

[sig,fs]=sig_competingtalkers(signame) additionally returns the sampling frequency fs.

The value of signame may be one of:

'one_speaker_reverb''

Examples:

The following plot shows an estimate of the power spectral density of the first channels of the speech shaped noise:

s=sig_competingtalkers('bnoise');
pwelch(s(:,1),hamming(150));
