The human voice appears to trigger pleasure circuits in the brains of typical kids, but not children with autism, a Stanford University team reports. The finding could explain why many children with autism seem indifferent to spoken words. The Stanford team used functional MRI to compare the brains of 20 children who had autism spectrum disorders and 19 typical kids. In typical kids there was a strong connection between areas that respond to the human voice and areas that release the feel-good chemical dopamine, but that connection was reduced in autistic children. Connections between voice areas and areas involved in emotion-related learning also were weaker, creating greater communication difficulties. The new study's suggestion that motivation is the problem could explain why speech often comes late to children with autism even though the brain circuit involved in processing spoken words seems to function normally; the reward circuitry isn't working the way it does in typical children.

"Language shapes our behavior and each word we use is imbued with multitudes of personal meaning. The right words spoken in the right way can bring us love, money and respect, while the wrong words-or even the right words spoken in the wrong way-can lead to a country to war.

"We discovered a language no one has seen or heard since the 16th or 17th century," Mr Quilter said, adding that the language appears to have been influenced by Quechua, an ancient tongue still spoken by millions of people across the Andes.

"All recordings are in English, are of native speakers, and include both English language dialects and English spoken in the accents of other languages."

"Every 14 days a language dies. By 2100, more than half of the more than 7,000 languages spoken on Earth ... may disappear." National Geographic wants to help by "identifying language hotspots ... and documenting the languages and cultures within them."

"A "hidden" language spoken by only about 1,000 people has been discovered in the remote northeast corner of India by researchers who at first thought they were documenting a dialect of the Aka culture, a tribal community that subsists on farming and hunting." Also has sound samples.

"Christian missionaries have become strangely vital to conserving endangered languages... In 1951 Pittman had started interviewing missionaries and linguists about the languages that were spoken in the parts of the world where they worked. The result was a language catalogue called Ethnologue... For example, the Spanish priests who followed the conquistadors into South America documented indigenous languages as they went."

Dogs mull over human speech much the way we do, and they try hard to decipher what we're saying to them, a new study suggests. The research, published in the journal Current Biology, shows that our dogs are riveted to our words.

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.

Researchers are using computer-animation techniques, such as motion-capture, to make life-like computer avatars that can reliably and naturally translate written and spoken words into sign language, whether it's American Sign Language or that of another country. The signing avatars can also be used in apps and games to help deaf children get early exposure to language, which is critical for their cognitive development.

The brains of jazz musicians who are engaged with other musicians in spontaneous improvisation show robust activation in the same brain areas traditionally associated with spoken language and syntax. In other words, improvisational jazz conversations "take root in the brain as a language"

To some extent, Americans have an advantage over much of the world's population: The country's two most widely spoken languages - English and Spanish - are among the most widely spoken worldwide. So, are Americans still willing to take language classes?

For decades, scientists thought perhaps smell was a diminished human sense and less valuable than other senses - like our glorious eyesight. "In the West, people came to this conclusion [through] the fact that we don't seem to have a good ability to talk about smells," says Asifa Majid, a professor of language and cultural cognition at Radboud University in the Netherlands. But Majid found that isn't universally true. Certain language speakers can name odors as easily as English speakers name colors, and the key difference may be how they live. Majid worked with speakers of four different languages: English and three from the Malay Peninsula. Two of these languages, Semaq Beri and Jahai, are spoken by hunter-gatherer groups. The other one, Semelai, is spoken by farmers. In order to test the ability of these language speakers to classify odors, Majid and her colleagues gave asked them to smell pen-shaped contraptions each filled with a different scent like leather, orange, garlic or fish - and then asked them to identify the smell. She also asked the participants to identify colors using different color chips. The farmer Semelai, like English speakers, found colors relatively easy to name and agreed with one another that the red chips were, indeed, red. When it came to identifying odors, the Semelai failed as miserably as the English speakers on the same tests. But both hunter-gatherer groups were much better at naming smells than the Semelai. In fact, they were just as good at identifying smells as colors. "That says something about the hunter-gatherer lifestyle," Majid says. There's a scarcity of English words that objectively describe odors, Majid says. Given that, readers of this article - written in English - may wonder how it's possible to describe a smell without leaning on other senses like taste (words like "sweet" or "sour") or emotional words like "gross." In English, most of our attempts to describe smells come from individual sources. You

Because text messaging is a conversation that involves a lot of back-and-forth, people add fillers as a way to mimic spoken language. We see this with the increased use of ellipses, which can invite the recipient to continue the conversation. The period is the opposite of that - a definitive stop that signals, as linguistics professor Mark Liberman has explained, "This is final, this is the end of the discussion." For some, this can appear angry or standoffish--but why? The use of the period is an example of what linguist John Gumperz termed situational code-switching: when we change how we talk depending on where we are, who we're talking to or how we're communicating. Using a period in a text message is perceived as overly formal, making the writer come across as insincere or awkward, just like using formal spoken language in a casual setting, like a bar.

One could argue that Niʻihau Hawaiian is the closest we've got to early forms of the language spoken in the islands. However, the language may be dying out. One interviewee noted the more frequent use of English amongst younger Ni`hau residents and expressed worry that when young speakers use English, they'll start to think in English, possibly leading them to abandon the Hawaiian way of thinking, and perhaps the language. Niʻihau speakers don't use diacritical marks like ʻokina (glottal stop) and kahakō (macron), which have become invaluable aids for language learners. They do, however, use "t"s and "r"s in place of "k"s and "l"s (e.g. ke aloha= te aroha, Ni`ihau style) - something that isn't taught in universities and immersion schools. Hawaiian language scholar Keao NeSmith says there's a history there. He says missionaries were confused by the Hawaiian language when they arrived. They were determined to translate the Bible into Hawaiian, but they couldn't figure out when to swap the "t" for the "k" and the "l" for the "r". So they created a standardized alphabet that dropped the use of "t'"s and "r"s. NeSmith says Niʻihau speakers chose not to alter their spoken language. But the missionary system gained a stronghold in the rest of the islands through the 1800s. Many of the Hawaiian language documents developed during this period, including newspapers, would become a go-to repository for the revitalization of the ʻōlelo Hawaiʻi a century later as the number of native speakers began to decline.

A team of researchers from Rice University and University of Maryland, College Park argue that it is more productive from a developmental perspective to describe spoken language as a special type of music. A review of existing studies presents a compelling case that musical hearing and ability is essential to language acquisition. In addition, we challenge the prevailing view that music cognition matures more slowly than language and is more difficult; instead, the researchers argue that music learning matches the speed and effort of language acquisition, and indeed, that "it is our innate musical intelligence that makes us capable of mastering speech." They conclude that music merits a central place in our understanding of human development.

The researchers of this study advance the idea that spoken language is introduced to the child as a vocal performance, and children attend to its musical features first. Without the ability to hear musically, it would be impossible to learn to speak. In addition, they question the view that music is acquired more slowly than language (Wilson, 2012) and demonstrate that language and music are deeply entangled in early life and develop along parallel tracks. Rather than describing music as a "universal language," they find it more productive from a developmental perspective to describe language as a special type of music in which referential discourse is bootstrapped onto a musical framework. Newborn infants' extensive abilities in different aspects of speech perception have often been cited as evidence that language is innate (e.g., Vouloumanos and Werker, 2007). However, these abilities are dependent on their discrimination of the sounds of language, the most musical aspects of speech. Music has a privileged status that enables us to acquire not only the musical conventions of our native culture, but also enables us to learn our native language. Without the ability to hear musically, we would be unable to learn language.
