Does this work? Is there such a thing? Do they get by, or do they resort to sign language or something? There is tone-deafness in speech, so…???
Please define “tone-deaf.”
Unable to distinguish differences in musical pitch.
What I’m specifically wondering about is speech and communication. I believe the phenomenon of tone-deafness refers more to production than reception (that is, I can hear the tones you’re producing but not reproduce them myself)…There has been research about tone-deafness as relates to speech…I’m Googling around now and I guess tone-deafness is “rare” in these populations, but I still wonder what happens to the few individuals affected…
I had been wondering the same and some months ago, in a somehow related thread, a poster mentionned that despite being tone deaf he didn’t have any issue learning to speak a tonal language.
Unfortunately I can’t seem to be able to find the thread. It was in GQ.
It should also be noted that in the speech of tonal language speakers, there are additional auditory clues given besides simple pitch.What are called “tones” vary not only in pitch, but in pitch movement (contour), volume, and duration.
In tonal languages, it isn’t the actual absolute pitch that forms part of the vocabulary. It’s the pitch change - whether you are speaking with a rising pitch, falling pitch, up in the middle, etc. Generally, only the direction has any meaning, not the musical interval involved - otherwise, you would have to be able to sing to talk. This is such a basic feature that even somebody totally unable to recognize related pitches forming a melody will still be able to detect that somebody rose in pitch while speaking a word, rather than falling in pitch.
Well, sort of.
It’s not a problem like you’d imagine. There’s essentially two types of tonal systems - register tones and contour tones. Languages with register tones simply use different pitches to distinguish certain syllables - a syllable can be high, or low, or (in some languages) in the middle. There’s a lot of languages with register tones in subsaharan Africa. To my knowledge, there’s no language with more than three register tones; the tonal systems in these languages are simple enough that they don’t tax the ability to handle pitches. Keep in mind that tone-deafness is not absolute, as mentioned above. While some people are less able than others to identify musical intervals, and things like that, it’s not as though they can’t distinguish a high sound from a low sound. Since register systems tend not to involve many different pitches, and since the distinctions are probably based more upon comparisons between neighboring syllables rather than an absolute idea of what the proper pitch should be, you can hear the difference no matter what. Especially since it’s only part of the phonological system of such a language - there’s lots of separate contextual data that’s assembled into figuring out what word someone said, and tone is only a part of it.
Contour systems are what yabob describes. An example are the Chinese languages. For instance, Mandarin has a high level tone, a falling tone, a rising tone, and a falling-rising tone. Each tone is distinguished by the shape of the pitch - how it falls and rises. Mandarin’s tone system is fairly simple, and each tone can be distinguished strictly based upon shape, without reference to absolute pitch at all. Some of the other Chinese languages are more complicated; Cantonese has six or seven (depending on dialect) and some of them share the same shape. Even so, the differences just don’t require making terribly subtle distinctions.
There’s some interesting research, though, that indicates that speakers of contour tonal languages tend to be fairly precise with the pitches they use to speak different tones - it’s an ability you develop as soon as you start talking, which trains the ear and voice to improve the ability to detect and create tones. In fact, one study suggests that absolute pitch (“perfect pitch”) is much more common among native speakers of tonal languages, to the point that it’s not at all rare. People receive intense training in it by virtue of speaking the language, which tends to eliminate the problem. Even for folks with no musical ear, though, being able to speak a tonal language doesn’t demand nearly the same ability to distinguish pitches that playing a musical instrument does.
