The sound of gesture: Ending of gesture use in language (and pronunciation) teaching

Quick reminder:  Only one week to sign up for the next haptic pronunciation teaching webinars! 

Sometimes getting a rise (ing pitch) out of students is the answer . . . This is one of those studies that you read where a number of miscellaneous pieces of a puzzle momentarily seem to come together for you. The research, by Pouw and colleagues at the Donders Institute. “Acoustic information about upper limb movement in voicing”, summarized by Neurosciencenews.com, is, well . . . useful.

In essence, what they "found" was that at or around the terminal point of a gesture, where the movement stops, the pitch of the voice goes up slightly (for a number of physiological reasons). Subjects, with eyes closed, could still in many cases identify the gesture being used, based on parameters of the pitch change that accompanied the nonsense words. The summary is what is fun and actually helpful, however.

From the summary:

"These findings go against the assumption that gestures basically only serve to depict or point out something. “It contributes to the understanding that there is a closer relationship between spoken language and gestures. Hand gestures may have been created to support the voice, to emphasize words, for example.”

Although the way the conclusion is framed might suggest that the researchers may have missed roughly three decades of extensive research on the function of gesture, from theoretical and pedagogical perspectives, it certainly works for me--and all of us who work with haptic pronunciation teaching. That describes, at least in part, what we do: "  . . . Hand gestures . . . created to support the voice, to emphasize words, for example.” Now we have even more science to back us up! (Go take a look at the demonstration videos on www.actonhaptic.com, if you haven't before.) 

What can I say? I'll just stop right there. Anything more would just be but an empty gesture . . .

The felt sense of a new or "replacement" vowel: Y-buzz and beyond

Clip art:

The first phase of EHIEP training is involved with haptically anchoring the vowels of English. Even if the learner "has" a vowel already in his or her repertoire, it is essential that a new and more focused, conscious awareness of the somatic qualities of the vowel be established to facilitate later change and monitoring of spontaneous speaking.

That concept is based on Lessac's notion of the "Y-buzz" sensation. Here is a 2007 study by Barrichelo and Behlau that looked at the perceptual salience of that highly resonant sound/sensation, as opposed to "normal" production by subjects of the acoustically similar [i] sound (as in the word, "me,' for example.) The unique, therapeutically created Y-buzz vowel felt sense is the model for our work. The learner's ability to produce the Y-buzz is almost entirely body-based, not auditory. In that way, the learner can produce it without having to "go through" the possibly "defective" [i] vowel in his or her current interlanguage phonology. (See earlier post on "changing the channel.")

Need to put a little more "buzz" in your teaching?
