Luis Salazar is CEO of Jobaline.
Luis: It doesn’t matter if you’re screaming or not.
Years and years of scientific studies and focus groups have dissected the human voice, and categorized the key emotions of the person speaking. Jobaline has taken that research and fed it into algorithms that interpret how a voice makes others feel, and cross-checks its judgment with real human listeners.
Luis: We’re not analyzing how the speaker feels. That’s irrelevant.
Regardless of whether you’re happy or sad, cracking jokes, your voice has a hidden, complicated architecture with that 2)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 helpline.
Luis: What is the emotion that that voice is going to generate on the listener?
So far, Salazar says, the Jobaline secret formula can pinpoint if a voice is engaging, calming and/or trustworthy. And note: it’s not a lie detector test. You could be a big liar, but just sound like someone honest.
Big companies pay Jobaline to help them 3)sift through thousands of applications to find the right workers for their hourly jobs. The startup says it’s processed over half a million voices for hotel receptionists, call-center staff.
Luis: In the hospitality industry, in the retail industry, you want people engage. The average span of attention these days is four seconds. In four...
Aarti Shahani (Reporter): I’m sorry, can you repeat that?
And the benefit isn’t just efficiency, cutting costs. We humans can get tired by the time applicant No. 25 comes through the door. We can discriminate. But algorithms have 4)stamina, and they do not 5)factor in things like age, race, gender, sexual orientation.
Luis: Correct. Math is blind, basically, right? That’s the beauty of math: it’s blind.

路易斯·薩拉查是招聘應用Jobaline的首席執行官。
路易斯:你是否在大吵大鬧,這并不重要。
多年以來,不少科學研究與各種研究小組都已經對人類聲音進行過深入分析,并對說話人的關鍵情緒做了歸類整理。Jobaline正是采用了這類研究成果,將其運用到算法當中——這些算法可以分析出一個聲音會讓聽者產生怎樣的感受,并能將其結論與真人聽者的反饋進行交叉比對。
路易斯:我們所分析的并不是說話人的感受,那是無關因素。
不管你是開心還是難過,或者正在講笑話,你的聲音當中一直隱藏著一種復雜的結構,這種本質上的特征就和指紋差不多。經過反復試驗與修正錯誤,這些算法現在可以更準確地判斷聲音活力、基礎頻率等因素對他人的影響,不論說話人是正在觀看電影的觀眾,還是撥打熱線電話求助的癌癥患者。
路易斯:那個聲音會讓聽者產生怎樣的感覺呢?
薩拉查表示,到目前為止,Jobaline的秘制公式已經可以準確判斷出一個聲音樣本到底是迷人的,還是平靜的,且/或可以信賴的。要注意的是,這并不是測謊儀測試。你完全可以是個大騙子,而你的聲音聽起來卻像個老實人。
有多家大公司請Jobaline幫他們篩選數千份簡歷,從中找出合適的小時工。作為一家新公司,Jobaline已經處理了超過五十萬份酒店接待員和呼叫中心員工應聘者的聲音樣本。
路易斯:在餐旅業和零售業中,你更希望員工能吸引他人的注意力。如今,人們的注意力平均只能維持四秒。……
