SRI-FRTIV

<h3>Introduction</h3><br>
<p>SRI-FRTIV (Five-way Recorded Toastmaster Intrinsic Variation) was developed by <a href="https://www.sri.com/">SRI International</a> in 2007-2008 and is comprised of approximately 232 hours of English speech from thirty-four speakers who were members of <a href="https://www.toastmasters.org/">Toastmaster</a> clubs. Participants were asked to speak at three different levels of effort (low, normal and high) in four different styles (interview, conversation, reading and oration) to study the question of how intrinsic variations -- associated with the speaker rather than the recording environment -- affect text-independent speaker verification.</p><br>
<h3>Data</h3><br>
<p>Participants were native speakers of North American English who were members of local Toastmasters clubs and had experience in public speaking. This release includes demographic information for 30 speakers (15 male, 15 female), including gender, birth year, height, education level, years in Toastmasters, and a self-evaluation of speaking skills.</p><br>
<p>Not all effort levels were applicable for each speaking style and so were not collected. Interviews and phone conversations were not recorded at high effort and oration was not recorded at low or normal effort levels.</p><br>
<p>Speech data is presented as 16kHz 16-bit single channel flac compressed pcm wav (.flac).</p><br>
