Re: Statistics for word rate in natural speech

Dunn and White (1940) is a classic report on speech measurements.  They assumed 1/8-second as the length of a syllable for their classic measurements.

The reference is:  Dunn, H.K. and White, S.D. (1940). Statistical Measurements on Conversational Speech.  Journal of the Acoustical Society of America 11:278-288.

Thank you.

I’m not a linguist or psycholinguist, so I write only from direct experience.

My reading is that the question is not very 'well-formed', and therefore the answers do not respond to the question.

The question was about ‘words’ [whatever they may happen to be], and the answers start with the idea of syllable, and Jont’s answer seems to be in ‘base phonemic elements’. For example, the two words, “I”, and “stopped”, count two words, each of one syllable, but ‘stopped’ is ccvcc [if the /p/ is pronounced].

10ms [ie 100Hz] seems to be a very small duration, and may only apply to a very limited number of phonemes. I had learned that the shortest time that was reliable for the [sequential] discrimination of auditory events was in the range of 25 to 40 ms — 40 to 25Hz. A ~16Hz limit works out to be around 60-70ms.

But sixteen “what’s”? Try the test. Record sixteen one syllable words, with cv or vc forms: be, am, so, it, two, aught, tea, ear, tie . . etc Most of these are two phonemes, or three if a diphthong is considered a grouped vowel, as in the word ‘tie’. Say them quickly. Edit them into a sequence with no gaps, and shorten the sequence to be 1,000ms. Is it possible to do sequential segmentation? leaving aside the articulatory problems.

Record: “I spied the top pie”, and “North-eastern Carolinian national seashore”. Both are ‘five words’. For interest, edit out the words: ‘top', ‘pie', ‘Carolinian', and ‘national’. Tricks such as producing the /d/ in spied as being the stopped diphthong /ai/, and the contracting of the /p/, and the /n/, likely increase the rate of delivery in natural speech, but most likely mostly in informal contexts.

“What was the question again?” cv ccvc cv ccvccvcvcvc
