CHICAGO, May 10, 2023 – African American English (AAE) is a variety of English spoken primarily, though not exclusively, by Black Americans of historical African descent. Because AAE varies from white American English (WAE) in a systematic way, it is possible that speech and hearing specialists unfamiliar with the language variety could misidentify differences in speech production as speech disorder. Professional understanding of the difference between typical variation and errors in the language system is the first step for accurately identifying disorder and establishing linguistic justice for AAE speakers.

(left) 5-year-old AAE girl’s production of “elephant.” When the /t/ sound in /nt/ is produced the AAE speaker produces less aspiration noise. The /t/ sound exists for a shorter period in time relative to the WAE /t/ production. The duration of the word is 740 milliseconds (.74 seconds). (right) 5-year-old WAE girl’s production of “elephant.” When the /t/ sound in /nt/ is produced the WAE speaker produces a lot of aspiration noise. The /t/ sound exists for a longer period in time relative to the AAE /t/ production. The duration of the entire word is 973 milliseconds (.97) seconds. Both girls have intelligible productions of the word “elephant.”

In her presentation, “Kids talk too: Linguistic justice and child African American English,” Yolanda Holt of East Carolina University will describe aspects of the systematic variation between AAE and WAE speech production in children. The talk will take place Wednesday, May 10, at 10:50 a.m. Eastern U.S. in the Los Angeles/Miami/Scottsdale room, as part of the 184th Meeting of the Acoustical Society of America running May 8-12 at the Chicago Marriott Downtown Magnificent Mile Hotel.

Common characteristics of AAE speech include variation at all linguistic levels, from sound production at the word level to the choice of commentary in professional interpersonal interactions. A frequent feature of AAE is final consonant reduction/deletion and final consonant cluster reduction. Holt provided the following example to illustrate word level to interpersonal level linguistic variation.

“In the professional setting, if one AAE-speaking professional woman wanted to compliment the attire of the other, the exchange might sound something like this: [Speaker 1] ‘I see you rockin’ the tone on tone.’ [Speaker 2] ‘Frien’, I’m jus’ tryin’ to be like you wit’ the fully executive flex.’’’

This example, in addition to using common aspects of AAE word shape, shows how the choice to use AAE in a professional setting is a way for the two women to share a message beyond the words.

“This exchange illustrates a complex and nuanced cultural understanding between the two speakers. In a few words, they communicate professional respect and a subtle appreciation for the intricate balance that African American women navigate in bringing their whole selves to the corporate setting,” said Holt.

Holt and her team examined final consonant cluster reduction (e.g., expressing “shift” as “shif’”) in 4- and 5-year-old children. Using instrumental acoustic phonetic analysis, they discovered that the variation in final consonant production in AAE is likely not a wholesale elimination of word endings but is perhaps a difference in aspects of articulation.

“This is an important finding because it could be assumed that if a child does not fully articulate the final sound, they are not aware of its existence,” said Holt. “By illustrating that the AAE-speaking child produces a variation of the final sound, not a wholesale removal, we help to eliminate the mistaken idea that AAE speakers don’t know the ending sounds exist.”

Holt believes the fields of speech and language science, education, and computer science should expect and accept such variation in human communication. Linguistic justice occurs when we accept variation in human language without penalizing the user or defining their speech as “wrong.”

“Language is alive. It grows and changes over each generation,” said Holt. “Accepting the speech and language used by each generation and each group of speakers is an acceptance of the individual, their life, and their experience. Acceptance, not tolerance, is the next step in the march towards linguistic justice. For that to occur, we must learn from our speakers and educate our professionals that different can be typical. It is not always disordered.”

Listening to the Largest Tree on Earth #ASA184

Hydrophones record the sounds of the massive Pando aspen grove, from its leaves to its roots.

CHICAGO, May 10, 2023 – Spread across 106 acres in southcentral Utah, the Pando aspen grove resembles a forest but is actually a single organism with more than 47,000 genetically identical aspen stems connected at the root. Pando is the world’s largest tree by weight and land mass. Research suggests Pando has been regenerating for 9,000 years, making it one of the oldest organisms on Earth.

As part of the 184th Meeting of the Acoustical Society of America, Jeff Rice and Lance Oditt will describe their work to reveal a unique acoustic portrait of this botanical wonder. Their presentation, “Beneath the tree: The sounds of a trembling giant,” will take place Wednesday, May 10, at 10:30 a.m. Eastern U.S. in the Great America 1/2 room, as part of the meeting running May 8-12 at the Chicago Marriott Downtown Magnificent Mile Hotel.

“Pando challenges our basic understanding of the world,” said presenter Jeff Rice, a sound artist from Seattle. “The idea that this giant forest could be a single organism defies our concept of the individual. Its vastness humbles our sense of space.”

After recording Pando’s leaves for The New York Times Magazine’s special issue “Listen to the World” in 2018, Rice returned in July 2022 as an artist-in-residence for the nonprofit group, Friends of Pando, which Oditt founded in 2019. Rice used a variety of microphones to record Pando’s leaves, birds, and weather.

“The sounds are beautiful and interesting, but from a practical standpoint, natural sounds can be used to document the health of an environment,” he said. “They are a record of the local biodiversity, and they provide a baseline that can be measured against environmental change.”

Rice was particularly captivated by the sound of vibrations passing through the tree during a windstorm. He wanted to see if they could record the sound of Pando’s root system, which can reach depths of 90 feet by some accounts. Oditt, executive director of Friends of Pando, identified several potential recording locations below the surface.

“Hydrophones don’t just need water to work,” said Rice. “They can pick up vibrations from surfaces like roots as well, and when I put on my headphones, I was instantly surprised. Something was happening. There was a faint sound.”

That sound is not conclusively from Pando’s root system. But a handful of experiments support the idea. Rice and Oditt were able to show that vibrations can pass from tree to tree through the ground. When they banged lightly on a branch 90 feet away, the hydrophone registered with a low thump. Rice compares this to the classic tin can telephone.

“It’s similar to two cans connected by a string,” he said. “Except there are 47,000 cans connected by a huge root system.”

A similar phenomenon occurred during a thunderstorm. As leaves moved more intensely in the wind, the signal recorded by the hydrophone also increased.

“The findings are tantalizing. While it started as art, we see enormous potential for use in science. Wind, converted to vibration (sound) and traveling the root system, could also reveal the inner workings of Pando’s vast hidden hydraulic system in a nondestructive manner,” said Oditt. “Friends of Pando plans to use the data gathered as the basis for additional studies on water movement, how branch arrays are related to one another, insect colonies, and root depth, all of which we know little about today.”

Small but Mighty: Insect-Inspired Microphones #ASA184

CHICAGO, May 10, 2023 – What can an insect hear? Surprisingly, quite a lot. Though small and simple, their hearing systems are highly efficient. For example, with a membrane only 2 millimeters across, the desert locust can decompose frequencies comparable to human capability. By understanding how insects perceive sound and using 3D-printing technology to create custom materials, it is possible to develop miniature, bio-inspired microphones.

Andrew Reid of the University of Strathclyde in the U.K. will present his work creating such microphones, which can autonomously collect acoustic data with little power consumption. His presentation, “Unnatural hearing — 3D printing functional polymers as a path to bio-inspired microphone design,” will take place Wednesday, May 10, at 10:05 a.m. Eastern U.S. in the Northwestern/Ohio State room, as part of the 184th Meeting of the Acoustical Society of America running May 8-12 at the Chicago Marriott Downtown Magnificent Mile Hotel.

“Insect ears are ideal templates for lowering energy and data transmission costs, reducing the size of the sensors, and removing data processing,” said Reid.

Reid’s team takes inspiration from insect ears in multiple ways. On the chemical and structural level, the researchers use 3D-printing technology to fabricate custom materials that mimic insect membranes. These synthetic membranes are highly sensitive and efficient acoustic sensors. Without 3D printing, traditional, silicon-based attempts at bio-inspired microphones lack the flexibility and customization required.

“In images, our microphone looks like any other microphone. The mechanical element is a simple diaphragm, perhaps in a slightly unusual ellipsoid or rectangular shape,” Reid said. “The interesting bits are happening on the microscale, with small variations in thickness and porosity, and on the nanoscale, with variations in material properties such as the compliance and density of the material.”

More than just the material, the entire data collection process is inspired by biological systems. Unlike traditional microphones that collect a range of information, these microphones are designed to detect a specific signal. This streamlined process is similar to how nerve endings detect and transmit signals. The specialization of the sensor enables it to quickly discern triggers without consuming a lot of energy or requiring supervision.

The bio-inspired sensors, with their small size, autonomous function, and low energy consumption, are ideal for applications that are hazardous or hard to reach, including locations embedded in a structure or within the human body.

Bio-inspired 3D-printing techniques can be applied to solve many other challenges, including working on blood-brain barrier organoids or ultrasound structural monitoring.

Fighting Racial Bias in Next-Gen Breast Cancer Screening #ASA184

A new virtual framework has enabled investigations into the effectiveness of optoacoustic tomography for cancer screening in darker-skinned individuals.

CHICAGO, May 9, 2023 – Breast cancer is one of the most common and deadly types of cancer, and the best outcomes stem from early detection. But some screening techniques may be less effective for people with darker skin.

Seonyeong Park of the University of Illinois Urbana-Champaign will discuss experiments to measure this bias in her talk, “Virtual imaging trials to investigate impact of skin color on three-dimensional optoacoustic tomography of the breast.” The presentation will take place Tuesday, May 9, at 6:15 p.m. Eastern U.S. in room Chicago F/G, as part of the 184th Meeting of the Acoustical Society of America running May 8-12 at the Chicago Marriott Downtown Magnificent Mile Hotel.

Current standard screening for breast cancer is done with X-ray mammography, which can be uncomfortable and is less effective on dense breast tissue. An alternative, optoacoustic tomography, uses laser light to induce sound vibrations in breast tissue. The vibrations can be measured and analyzed to spot tumors. This method is safe and effective and does not require compression during imaging.

The technology that underlies OAT imaging is not new; it has been used in pulse oximetry for decades. Concerns about its interaction with darker skin have existed for almost as long.

“In 1990, a study found that pulse oximetry was about 2.5 times less accurate in patients with dark skin,” said Park. “Recently, an article suggested that unreliable measurements from pulse oximeters may have contributed to increased mortality rates in Black patients during the COVID-19 pandemic.”

With OAT emerging as an effective breast cancer screening method, Park and her team, led by professors Mark Anastasio at UIUC and Umberto Villa at the University of Texas at Austin, collaborating with professor Alexander Oraevsky of TomoWave Laboratories, Inc. in Houston, wanted to determine if this same bias was present. Rather than navigate the cost and ethics issues surrounding human test subjects, the team instead simulated a range of skin colors and tumor locations.

“By using an ensemble of realistic numerical breast phantoms, i.e., digital breasts, the evaluation can be conducted rapidly and cost-effectively,” said Park.

The results confirmed that tumors could be harder to locate in individuals with darker skin depending on the design of the OAT imager and the location of the tumor. Fortunately, a virtual framework developed by Park allows for more comprehensive investigations and can serve as a tool for evaluating and optimizing new OAT imaging systems in their early stages of development.

“To improve detectability in dark skin, the laser power to acoustic noise ratio should be increased,” said Park. “It is recommended that skin color-dependent detectability should be evaluated when designing new OAT breast imagers. Our team is actively conducting in-depth investigations utilizing our virtual framework to propose effective strategies for designing imaging systems that can help mitigate racial bias in OAT breast imaging.”

Hey Siri, Can You Hear Me? #ASA184

Experiments show how speech and comprehension change when people communicate with artificial intelligence.

CHICAGO, May 9, 2023 – Millions of people now regularly communicate with AI-based devices, such as smartphones, speakers, and cars. Studying these interactions can improve AI’s ability to understand human speech and determine how talking with technology impacts language.

In their talk, “Clear speech in the new digital era: Speaking and listening clearly to voice-AI systems,” Georgia Zellou and Michelle Cohn of the University of California, Davis will describe experiments to investigate how speech and comprehension change when humans communicate with AI. The presentation will take place Tuesday, May 9, at 12:40 p.m. Eastern U.S. in the Los Angeles/Miami/Scottsdale room, as part of the 184th Meeting of the Acoustical Society of America running May 8-12 at the Chicago Marriott Downtown Magnificent Mile Hotel.

In their first line of questioning, Zellou and Cohn examined how people adjust their voice when communicating with an AI system compared to talking with another human. They found the participants produced louder and slower speech with less pitch variation when they spoke to voice-AI (e.g., Siri, Alexa), even across identical interactions.

On the listening side, the researchers showed that how humanlike a device sounds impacts how well listeners will understand it. If a listener thinks the voice talking is a device, they are less able to accurately understand. However, if it sounds more humanlike, their comprehension increases. Clear speech, like in the style of a newscaster, was better understood overall, even if it was machine-generated.

“We do see some differences in patterns across human- and machine-directed speech: People are louder and slower when talking to technology. These adjustments are similar to the changes speakers make when talking in background noise, such as in a crowded restaurant,” said Zellou. “People also have expectations that the systems will misunderstand them and that they won’t be able to understand the output.”

Clarifying what makes a speaker intelligible will be useful for voice technology. For example, these results suggest that text-to-speech voices should adopt a “clear” style in noisy conditions.

Looking forward, the team aims to apply these studies to people from different age groups and social and language backgrounds. They also want to investigate how people learn language from devices and how linguistic behavior adapts as technology changes.

“There are so many open questions,” said Cohn. “For example, could voice-AI be a source of language change among some speakers? As technology advances, such as with large language models like ChatGPT, the boundary between human and machine is changing – how will our language change with it?”

Warmer Climate Could Cause Puerto Rico’s Frogs to Croak #ASA184

Rising temperatures leave their mark in the distinctive calls of the coqui frog.

CHICAGO, May 8, 2023 – The coqui frog is one of Puerto Rico’s most iconic animals. It gets its name from its distinctive two-note call, “co-qui,” which can be heard throughout the island every night. The males of the species produce these calls to mark their territory and ward away rivals, but scientists can also use them to study the changing climate.

Peter Narins of the University of California, Los Angeles will describe changes in the calls of the coqui frog over a 23-year period in his talk, “Climate change drives frog call change in Puerto Rico: Predictions and implications.” The presentation will take place Monday, May 8, at 2:40 p.m. Eastern U.S. in room Chicago F/G, as part of the 184th Meeting of the Acoustical Society of America running May 8-12 at the Chicago Marriott Downtown Magnificent Mile Hotel.

Over two decades ago, Narins recorded the sounds of the coqui frog along the slopes of Puerto Rico’s El Yunque Peak. His team discovered the calls changed based on elevation. Like all amphibians, coqui frogs are highly sensitive to changes in temperature. On cold mountain peaks, the frogs grow larger than in warmer valleys, and this size discrepancy is reflected in their calls.

“Coqui that produced short, high-pitched calls at high rates lived near the base of the mountain, while the calls of animals living near the mountain’s peak were longer, lower-pitched, and repeated less frequently,” said Narins.

Upon returning to the mountain two decades later, Narins and a team including colleague Sebastiaan Meenderink discovered that every frog call had grown higher in pitch.

“In order to record a call with certain characteristics we had to move to a slightly higher altitude,” said Meenderink. “It was as if all the animals had moved up the mountain.”

This mini-migration corresponds with the temperature shift induced by climate change and foreshadows a dire future for the coqui. As temperatures continue to rise, the frogs will continue to retreat up the mountain until they run out of room.

“For now, the consequences are not dire,” said Meenderink. “A barely perceptible change in frog body size and call has little impact on the environment. However, if left unabated, the temperature increase will eventually cause a collapse of the coqui population, which will be catastrophic for the Puerto Rican ecosystem.”
