Devoicing and Voicing; Ice skating rinks; PPG Place

"Devoicing" occurs when a "voiced" sound (a sound that is made with the vocal cords vibrating) is made into a "voiceless" sound (a sound that is made without the vocal cords vibrating).  For example, a /b/ sound may turn into a /p/ sound; the sounds are made in similar ways, except that when we say /b/ our vocal cords vibrate and when we say /p/ our vocal cords don't vibrate.  Thus, when saying "tub," a child may say "tup" in error.  The error often occurs with the last consonant sound in a word.

"Voicing" occurs when a "voiceless" sound (a sound that is made without the vocal cords vibrating) is made into a "voiced" sound (a sound that is made with the vocal cords vibrating).  For example, a /p/ sound may turn into a /b/ sound; the sounds are made in similar ways, except that when we say /p/ our vocal cords don't vibrate and when we say /b/ our vocal cords vibrate.  Thus, when saying "potty," a child may say "botty" in error.  The error often occurs with the first consonant sound in a word.

It is important to note that a child can produce all the sounds in the word correctly, so this is not an articulation problem per se.  Rather, this what experts call a "phonological process" whereby a child produces a different "rule" when saying words.  In the case of devoicing, the "rule" the child is applying is to make the sounds without vibrating the vocal cords.  In the case of voicing, the "rule" the child is applying is to make the sounds while vibrating the vocal cords.

To reduce devoicing, it is helpful to model production of the word correctly for your child.  For example, say "tub" and emphasize the /b/ sound; say this over and over.  Then, prompt your child to say "tub" correctly.  If it is still in error, a good cue is, "Turn on your voice."  Explain to your child that some sounds are made with our voice on, like with /b/; other sounds are made with our voice off, like with /p/.  Review this notion with other sounds, like the difference between "zzzzzz" and "ssssss;" have your child feel her throat (or yours) when making these sounds to sense/understand the concept of voicing/vibration.  You may find it helpful to practice the sounds alone at first so that your child gets used to responding to the cue "Turn on your voice."  Good sounds to practice include b/p, d/t, z/s, g/k.  Also, try breaking up the word.  In the case of "tub," prompt her to say "buh;" then "-ub;" then "tub."  Breaking up the word can help build awareness of the sounds in the word.  It is also highlights to your child that she can make all the sounds in the word successfully.  In addition, the slow pace allows her time to produce the correct sounds.

I thought it might be fun to practice elimination of voicing and devoicing at an ice skating rink, since the days of coldness are (hopefully!) numbered.  Unfortunately the Cal U Ice Rink at PPG Place is closed for the season, as are Allegheny County outdoor ice skating rinks.  However, there are plenty of indoor ice skating rinks in Pittsburgh.  A few I know of include: the Iceoplex at Southpointe, the Ice Castle Arena, and the Mt. Lebanon Ice Center.

If ice skating isn't your cup of tea, but you are still keen on visiting PPG Place, there are some target words for that location that will be relevant this spring.  PPG Place will soon be opening up its plaza to include the water feature.
