Howard University And Google Team Up To Advance AI Speech Recognition For African American English
In a significant move toward advancing inclusivity in technology, Howard University and Google Research have unveiled a new dataset designed to enhance how automatic speech recognition (ASR) systems serve Black users. The collaboration, part of Project Elevate Black Voices , involved researchers traveling nationwide to document the unique dialects, accents, and speech patterns commonly found in Black communities, features often misinterpreted or ignored by current AI systems.
The project spotlights African American English (AAE)—also known as African American Vernacular English, Black English, Ebonics, or simply 'Black talk'—a culturally rich and historically rooted linguistic form. Due to systemic bias in the development of AI tools, Black users have frequently encountered errors or been misunderstood by voice technologies, sometimes feeling pressured to alter their natural speech just to be recognized by these systems— a classic form of code switching.
Researchers at Howard University and Google are on a mission to change this.
'African American English has been at the forefront of United States culture since almost the beginning of the country,' shared Gloria Washington, Ph.D., a Howard University researcher and the co-principal investigator of Project Elevate Black Voices , in a press release. 'Voice assistant technology should understand different dialects of all African American English to truly serve not just African Americans, but other persons who speak these unique dialects. It's about time that we provide the best experience for all users of these technologies.'
To build this groundbreaking dataset, researchers gathered 600 hours of speech from participants representing various AAE dialects across 32 states. The goal was to confront hidden barriers that hinder the effectiveness of automatic speech recognition (ASR) systems for Black users. One of the key findings was that AAE is significantly underrepresented in existing speech datasets, not because the language isn't spoken, but because many Black users have been socially conditioned to alter their natural speech when interacting with voice technology. This phenomenon, often rooted in the need to be understood by systems that don't recognize AAE, leads to a lack of authentic representation.
A 2023 Google blog post highlighted another challenge: privacy and security policies, while essential, create additional constraints on the collection of AAE-specific voice data. These self-imposed limits make it harder to amass the scale and authenticity of data required to close the gap in performance.
Despite these challenges, progress is being made. Researchers are now using dialect classifiers to identify AAE within broader datasets, a promising first step toward building more inclusive technologies. Howard University will maintain ownership and licensing rights to the dataset, serving as its ethical guardian to ensure it's used responsibly and for the benefit of Black communities. Google, in turn, will be able to use the dataset to enhance its own ASR products, part of a broader effort to make AI tools more equitable across dialects, languages, and accents globally.

This Pixel 10 leak offers another dose of that stunning Indigo hue
TL;DR New marketing images of the Pixel 10 series have been leaked. The leak mainly focuses on the base model, but also includes images of the Pro and XL. After the color options for the Pixel 10 initially leaked, we threw up a poll asking our readers what their favorite color was. Out of those four options, Indigo emerged as the clear winner. Now everyone's favorite colorway is back in the spotlight in the latest Pixel 10 leak. This leak offers a glimpse at the Pro models as well. We have been treated to another helping of Pixel 10 leaks, this time from tipster Evan Blass. This leak comes in two parts: one focusing squarely on the base model and the other showcasing the whole family. As mentioned earlier, we get a healthy dose of the Pixel 10 in the new Indigo colorway. It has a similar vibe to the 'Really Blue' hue that appeared on the original Pixel phone, arguably one of the best colors Google has used for its devices. In one of the images, we also see the Frost (light blue) and Lemoncello (yellow) color options. From earlier leaks, we know that the vanilla Pixel 10 should have a 6.3-inch FHD+ display that's protected by Corning Gorilla Glass Victus 2. Inside, it's expected to have a Tensor G5 chip, a 4,970mAh battery, 29W wired charging, 15W wireless charging, 12GB of RAM, and 128GB or 256GB of storage. As for that new triple camera setup, there should be a 50MP Samsung GN8 primary camera, a 13MP Sony IMX712 ultrawide camera, and an 11MP Samsung 3J1 telephoto camera. The next part of the leak features the Pro models, including the Fold. These marketing images come only days after we saw the Pixel 10 Pro from every angle. And only a day after Google's largest Pixel 10 model also leaked. Here, we see the entire series, except for the base model, in the new Moonstone colorway. We won't have to wait too much longer for the Pixel 10 series unveiling, as it's slightly less than two weeks away at this point. The next generation flagship should also be joined by the launch of the Pixel Watch 4 and Pixel Buds 2a. Follow

Big Tech's colossal capex spending could be offsetting the impact of tariffs
President Donald Trump's tariffs continue to cast uncertainty over financial markets. Meanwhile, many leading tech companies have reported strong earnings and spending growth. Some experts speculate that this could help offset the impact of the tariffs. Each round has complicated the economic landscape and raised uncertainty, especially as some companies struggle under the weight of these policies. However, many leading tech companies have made it clear that they don't intend to scale back their spending. Amazon, Apple, Google, Microsoft, and Meta Platforms all increased their capex guidance for 2025. As one expert sees it, this could be exactly what helps offset the impact of Trump's tariffs. "These mega-cap tech companies haven't just powered the S&P 500's rebound and pushed the NASDAQ to new highs since the post-Liberation Day lows," wrote Larry Adam, CIO of Raymond James, in a note on Wednesday. "They've also helped offset the drag from tariffs and tight Fed policy through massive capital spending." Adam isn't the only one who sees this as a distinct possibility. Eugenia Mykuliak, founder and executive director of B2Prime, highlighted the importance of Big Tech's spending spree for the broader economy. "Although it seems to be a different story from tariffs, these companies help the economy by creating jobs and keeping stock markets strong," she said. She credited the tech sector's growth with helping soften the blows dealt to the market by Trump's ongoing tariffs and the Federal Reserve's ongoing refusal to cut interest rates. Kroll managing director Carla Nunes also predicts that the high AI and data center spending from mega-cap tech leaders will likely mitigate the effects of tariffs. However, she also noted that she doesn't believe it will offset the impact of other economic trends. "The impacts of tariffs on real economic activity will take some time to be fully reflected in economic data, so the longer-term impact needs to be interpreted with caution," Nunes stated.
