Would You Repeat That, Please?

Forget the resume and the interview.  Does the guy sound like he’s right for the job?

Unlike facial recognition technology, in which algorithms analyze your smile  and face to determine your mood, voice analysis tries to answer the question of what impact your voice is going to have on the listener

Years and years of scientific studies and focus groups have dissected the human voice and categorized the key emotions of the person speaking.

The company Jobaline has taken that research and fed it into algorithms that interpret how a voice makes others feel and then cross-checks its judgment with real human listeners.

“We’re not analyzing how the speaker feels,” says Luis Salazar, CEO of Jobaline.. “That’s irrelevant.”

So far, Salazar says, the Jobaline secret formula can pinpoint if a voice is engaging, calming, and/or trustworthy.

Regardless of whether you’re happy, sad or cracking jokes, your voice has a hidden, complicated architecture with an intrinsic signature — much like a fingerprint. And through trial and error, the algorithms can get better at predicting how things like energy and fundamental frequency impact others — be they people watching a movie, or cancer patients calling a help line.

Through machine learning and multiple feedback loops, it keeps answering and homing in on Salazar’s question: “What is the emotion that that voice is going to generate on the listener?”

Use It For Hiring

Big companies pay Jobaline to help them sift through thousands of applications to find the right workers for their hourly jobs. Human recruiters make the final judgment, but the startup determines the small pool that gets human consideration.

Jobaline says it has processed over half a million voices for positions including sales, janitorial staff and call center workers.

The benefit of computer automation isn’t just efficiency or cutting costs. Humans evaluating job candidates can get tired by the time applicant No. 25 comes through the door. Those doing the hiring can discriminate. But algorithms have stamina, and they do not factor in things like age, race, gender or sexual orientation. “That’s the beauty of math,” Salazar says. “It’s blind.”
