Can speech rate in English be reliably measured through the beat rate?
Beat rate analysis is now pretty standard, and a plethora of algorithms can reliably measure beat rate — typically in beats per minute (bpm) — of all sorts of formats (e.g. mp3, wav, ogg, etc). Speech rate analysis is typically done by transcribing recorded speech, and measuring it — usually in words per minute, and more robustly in syllables per minute (or per second, no difference) — but could perhaps be well approximated via the bpm measure.
Can it? Does each word in English correlate to a beat via a single tonic syllable?
