Artie releases tool to measure bias in speech recognition models

Last Chance: Register for Transform, VB’s AI occasion of the 12 months, hosted on-line July 15-17.


Artie, a startup growing a platform for cellular video games on social media, at the moment launched a data set and tool for detecting demographic bias in voice apps. The Artie Bias Corpus (ABC), which consists of audio recordsdata together with their transcriptions, goals to diagnose and mitigate the influence of things like age, gender, and accent in voice recognition techniques.

Speech recognition has come a good distance since IBM’s Shoebox machine and Worlds of Wonder’s Julie doll. But regardless of progress made attainable by AI, voice recognition techniques at the moment are at greatest imperfect — and at worst discriminatory. In a examine commissioned by the Washington Post, in style sensible audio system made by Google and Amazon have been 30% much less prone to perceive non-American accents than these of native-born customers. More just lately, the Algorithmic Justice League’s Voice Erasure challenge discovered that that speech recognition techniques from Apple, Amazon, Google, IBM, and Microsoft collectively obtain phrase error charges of 35% for African American voices versus 19% for white voices.

The Artie Bias Corpus is a curated subset of Mozilla’s Common Voice corpus representing three gender lessons, eight age ranges (from 18 to 80), and 17 totally different accents in English. In addition to 2.Four hours of audio (1,712 particular person clips) and transcriptions vetted by votes on the Common Voice net platform and native-speaker specialists, it contains self-identified, opt-in demographic information about audio system.

In a proof of idea, Artie researchers utilized the Artie Bias Corpus to Mozilla’s open supply DeepSpeech fashions, which have been educated on a minimum of one corpora with a recognized bias towards North American English. In one other experiment, they evaluated gender bias in publicly out there Google and Amazon U.S. English fashions.

According to the researchers, DeepSpeech certainly confirmed a bias towards U.S. and Great British accents, however not a gender bias. On the opposite hand, as of early December 2019, Google’s U.S. English mannequin confirmed “statistically significant” gender bias in contrast with Amazon Transcribe’s U.S. English mannequin, acting on common 6.4% worse on feminine audio system.

“Fairness is one of our core AI principles, and we’re committed to making progress in this area,” a Google spokesperson informed VentureBeat “We’ve been working on the challenge of accurately recognizing variations of speech for several years, and will continue to do so. In the last year we’ve developed tools and data sets to help identify and carve out bias from machine learning models, and we offer these as open source for the larger community.”

“As voice technology becomes more common, we discover how fragile it can be … In some cases, demographic bias can render a technology unusable for someone because of their demographic,” Josh Meyer, lead scientist at Artie and a analysis fellow at Mozilla, wrote in a weblog publish. “Even for well-resourced languages like English, state of the art speech recognizers cannot understand all native accents reliably, and they often understand men better than women … The solution is to face the problem, and work toward solutions.”
