Scientists are reporting in the journal Science that they have identified specialized brain cells that help us understand what a speaker really means. These cells do this by keeping track of changes in the pitch of the voice. "We found that there were groups of neurons that were specialized and dedicated just for the processing of pitch," says Dr. Eddie Chang, a professor of neurological surgery at the University of California, San Francisco. Chang says these neurons allow the brain to detect "the melody of speech," or intonation, while other specialized brain cells identify vowels and consonants. "Intonation is about how we say things," Chang says. "It's important because we can change the meaning, even - without actually changing the words themselves." The identification of specialized cells that track intonation shows just how much importance the human brain assigns to hearing, says Nina Kraus, a neurobiologist who runs the Auditory Neuroscience Laboratory at Northwestern University. "Processing sound is one of the most complex jobs that we ask our brain to do," Kraus says. And it's a skill that some brains learn better than others, she says. Apparently, musicians, according to a study conducted by Kraus, are better than non-musicians at recognizing the subtle tonal changes found in Mandarin Chinese. On the other hand, recognizing intonation is a skill that's often impaired in people with autism, Kraus says. "A typically developing child will process those pitch contours very precisely," Kraus says. "But some kids on the autism spectrum don't. They understand the words you are saying, but they are not understanding how you mean it." The new study suggests that may be because the brain cells that usually keep track of pitch aren't working the way they should.

Provides information on pitch in general and its relation to learning language, particularly pinpointing areas of the brain that process and interprets pitch in language.

Research studies have shown that music and language have a correlation between them to the human mind and support the close relationship between music and language functions. There is evidence that speech functions can benefit from music functions and vice versa. One is example is that phonological awareness, pivotal for reading and writing skills, is closely related to pitch awareness and musical expertise. Some research papers also discuss the relationship between tonal language expertise and musical pitch perception skills and on whether pitch-processing deficits might influence tonal language perception. Overall all, these studies provide a comprehensive summary of the current knowledge on the tight relationship between music and language functions.

Although it has a genetic component, most believe perfect pitch - or absolute pitch - is a primarily a function of early life exposure and training in music, says Takao Hensch, professor of molecular and cellular biology at Harvard. Hensch is studying valprioc acid, a drug which might allow adults to learn perfect pitch by re-creating this critical period in brain development. "It's a mood-stabilizing drug, but we found that it also restores the plasticity of the brain to a juvenile state," Hensch says. Valprioc acid allows the brain to absorb new information as easily as it did before age 7. Hensch's findings have potentially valuable implications for other critical-period-related developments, language being one. So the sci-fi question: in the future, can we come up with a way to reopen plasticity, [and] paired with the appropriate training, allow adult brains to become young again?

This article talked about how adults talk to babies and why we do it. When we talk to babies, we tend to raise our pitch a little and supposedly, it calms the baby down. They also talked about a research project where they recorded adults from different parts of the world, and noticed that those who come from western places raised their pitch the most, and in remote places didn't raise their pitch that much but everyone raised their pitch at least a little. The way we talk to babies is universal and we've evolved as humans to be able to communicate with infants.

The features of baby talk - softer tone, higher pitch, almost unintelligible vocabulary - are global. Researchers at Harvard's Music Lab documented over 1,500 recordings in 21 urban, rural and Indigenous communities - making their work possibly a first of its kind experiment. The article includes samples from different languages around the world. There are many reasons why baby talk might have evolved in humans and why it might serve beneficial purposes. Some theories suggest that the way we speak accentuates the vowels of the speech and helps babies learn speech. Other theories suggest that this kind of baby talk helps regulate the baby's emotions and helps structure the social interactions we have with babies, so it helps socialize them and control their behavior and mood. In prehistoric times, having ways to interact with babies and to care for them while still being able to keep your eyes up to look out for predators and use your voice to interact with babies, might have been an important reason why we may have evolved these kinds of behaviors.

Amusia is a deficit in musical memory, recognition, and in pitch processing that people can be born with or acquire through brain damage. Some people may think of themselves as being "tone-deaf", but most of these "bad" singers are just that. People with amusia are so unable to hear tones that they even struggle to differentiate between questions and statements when spoken. Language, like music, uses sound to convey meaning; be it a story, or simply an emotion. In fact, music and spoken language use many of the same structural elements: pitch, duration, intensity and melodic contour, to name a few. Melodic contour is the pattern in which pitch changes from high to low over time. This contouring of pitch is often used to express emotion in music. The emotional effect of contouring is appreciated across many cultures and across many age groups. In speech, melodic contour is created by intonation, which allows us to place emphasis upon certain words and distinguish the purpose of the sentence; e.g. whether it is a question, statement or command. These comparisons provide evidence for the overlap of brain areas and mechanisms that underlie speech and music processing. In addition, the storing of sound patterns in short-term memory is also overlapping for both language and music.

the micro-nuances of their speech patterns, and how voters, and viewers, hear them - can also provide a fascinating window into how we perceive authority and who occupies it. Women and men tend to have different speech patterns, linguists will tell you. Women, especially young women, tend to have more versatile intonation. They place more emphasis on certain words; they are playful with language and have shorter and thinner vocal cords, which produce a higher pitch. That isn't absolute, nor is it necessarily a bad thing - unless, of course, you are a person with a higher pitch trying to present yourself with some kind of authority. A 2012 study published in PLoS ONE found that both men and women prefer male and female leaders who have lower-pitched voices, while a 2015 report in a journal called Political Psychology determined, in a sample of U.S. adults, that Americans prefer political candidates with lower voices as well. Lower voices do carry better, so that's not entirely without basis, said the linguist Deborah Tannen.

In many languages, pitch is as important as consonants and vowels for distinguishing one word from another. In English, "pay" and "bay" are different because they have different starting sounds. But imagine if "pay" said on a high pitch meant "to give money," while "pay" said on a low pitch meant "a broad inlet of the sea where the land curves inward." That's what it feels like to speak what linguists call a tonal language. At least a billion and a half people worldwide do it their entire lives and think nothing of it. The article goes on to talk about which areas of the world have the highest concentration of tonal languages and reasons why that might be, also some of the advantages of speaking a tonal language.

We start building our sense of people's personalities from the first words they utter. Phil McAleer, of the University of Glasgow, ran an experiment where he recorded 64 people, men and women, from Glasgow, reading a paragraph that included the word "hello." He then extracted all the hellos and got 320 participants to listen to the different voices and rate them on 10 different personality traits, such as trustworthiness, aggressiveness, confidence, dominance and warmth. Interestingly, participants largely agreed on which voice matched which personality trait. One male voice was overwhelmingly voted the least trustworthy. The pitch of the untrustworthy voice was much lower than the male deemed most trustworthy. McAleer says this is probably because a higher pitched male voice is closer to the natural pitch of a female, making the men sound less aggressive and friendlier than the lower male voices. What makes females sound more trustworthy is whether their voices rise or fall at the end of the word, says McAleer. "Probably the trustworthy female, when she drops her voice at the end, is showing a degree of certainty and so can be trusted." (Perhaps a reason to avoid uptalk, if you're female?)

This study shows the science behind first impressions, and how certain voices can affect first impressions.

Language is not static but dynamic, constantly evolving to suit the fashions of the time and this results in shifts in pronunciation and pitch. In the UK, for instance, far fewer people talk with "received pronunciation" these days - and even Queen Elizabeth II's voice has lost some of the cut-glass vowels of her youth. This is thought to reflect a more general shake-up in Britain's social hierarchies, leading to a kind of linguistic cross-pollination between the classes that has even reached Her Majesty. Women today speak at a deeper pitch than their mothers or grandmothers would have done, thanks to the changing power dynamics between men and women.

In many languages, such as Mandarin Chinese, pitch is as important as consonants and vowels for distinguishing one word from another. Tone languages are spoken all over the world, but they tend to cluster in three places: East and Southeast Asia; sub-Saharan Africa; and among the indigenous communities of Mexico. There are certain advantages to speaking tone languages. Speakers of some African languages can communicate across long distances playing the tones on drums, and Mazatec-speakers in Mexico use whistling for the same purpose. Also, speakers of tonal languages are better at identifying musical pitches than speakers of non-tonal languges.

This article explains an experiment that was conducted, with the aim to find if people change the pitch of their voice when talking to different people. The experiment had participants to undergo a simulated job interview. The experiment found that people speak in a higher pitched voice when speaking to someone whom they believe is more dominant.

Examines the languages of Mandarin and Vietnamese and how people who speak these languages are more likely to have perfect pitch. Includes various studies performed and poses an interesting question to think about.

A very detailed account of perfect pitch and its relation to learning language. An informative and interesting site!

""Interviewers who spoke moderately fast, at a rate of about 3.5 words per second, were much more successful at getting people to agree than either interviewers who talked very fast or very slowly," said Jose Benki... variation in pitch could be helpful for some interviewers but for others, too much pitch variation sounds artificial, like people are trying too hard. ... "People who pause too much are seen as disfluent. But it was interesting that even the most disfluent interviewers had higher success rates than those who were perfectly fluent.""

It's not just what you say, it's the way that you say it. The sound of our voices, including its pitch, accent and inflection, has all sorts of subtle effects on how we are perceived by other people. This article lists 10 ways that our voices influence others' conception of us and provides links to the relevant studies.

Why one syllable words spoken at different pitches can have seven meanings. People don't generally speak in a monotone.

Bilingual babies use cues such as pitch or word duration to tell two languages apart. Babies in bilingual environments can learn to distinguish the grammatical structures of two different languages at a young age. The research shows that bilingual babies use qualities like pitch and duration of sounds to keep two languages separate.

Introduction: There is not one single Chinese language, but many different versions or dialects including Wu, Cantonese and Taiwanese. Northern Chinese, also known as Mandarin, is the mother tongue of about 70% of Chinese speakers and is the accepted written language for all Chinese.

This article talks about the differences between Chinese and English regarding the alphabet, phonology, and grammar. Chinese doesn't use an alphabet, but a logographic system where the symbols themselves represent the words. This causes Chinese learners to have difficultly reading English texts and spelling words correctly. Because Chinese is a tonal language, the pitch of a sound is what distinguishes the word meaning whereas, in English, changes in pitch are used to emphasize or express emotion and not give a different word meaning to the sound. Chinese grammar is also very much different from English grammar. For example, English uses a lot of auxiliaries and verb inflections, but Chinese is an uninflected language and conveys meaning through word order and shared understanding of context. For example, time in Chinese does not go through the use of different tenses and verb forms, which makes it difficult to understand the complexities of things like is/are/were and eats, eat, ate, eaten.
