Meta的AI翻译器可以解释无文字的语言 扎克伯格以闽南话举例_我的网站

A |     世界上大约7000种已知的语言中，有将近一半的语言，也就是其中的十分之四是口耳相传，没有包含书面内容。这些无文字的语言给现代机器学习翻译系统带来了一个独特的问题，因为它们通常需要在翻译到新语言之前将口头语言转换为书面文字，并将文字还原为语音，但Meta公司已经通过其最新的开源语言AI进展解决了这个问题。    The cell phones, tablets, and laptops left behind by veterans who died by suicide may offer insight that could help prevent future military suicides, according to a nonprofit dedicated to analyzing the data from the devices.Stop Soldier Suicide collects the technology as part of its initiative, "The Black Box Project," which is named after the black boxes found on planes that help determine the cause of aviation incidents."If we could gather novel data from those that have died by suicide, we might be able to recreate the last year of life," Stop Soldier Suicide CEO Chris Ford told ABC News.Veterans are 57% more at risk for suicide than non-military adults and around 6,000 veterans die by suicide each year, according to the Department of Veterans Affairs."I think we can prevent needless suffering and a ton of loss of life," Ford said.That kind of loss is something David McDaniel, whose son Connor died by suicide at the age of 26, knows all too well.Connor McDaniel joined the Army after high school, and, according to David, he appeared upbeat during his deployment to Afghanistan, where he was assigned to protect local villages from the Taliban."Some of his Army buddies told me that he was making them laugh while they were being shelled in Afghanistan," David McDaniel told ABC News.But it wasn't long after Connor came home that David McDaniel says he sensed a shift in his son's behavior to include "more anger, a lot of frustration, a lot of gloominess."On Sept. 1, 2021, David says his son entered a wooded area with a firearm."I start screaming his name as I'm walking up the field. And just then the police, the sheriff's department shows up and they tell me to come back down," McDaniel said.He followed their direction, but on the car ride home, an officer called him and said Connor was dead after he fired upon sheriff's deputies and the deputies returned fire and killed him.Connor's death was determined to be a suicide. The district attorney's office concluded that the officers' actions were justified.While grappling with his son's death, David McDaniel was immediately drawn to the Black Box Project, which uses forensic software to unlock and comb through service members' devices provided by their loved ones to review their activity in the weeks leading up to their suicides.McDaniel works in the tech field and says if the project can find repeated patterns in online searches, they may be able to help others to prevent suicides.For instance, McDaniel says his son searched for SGLI, Servicemembers' Group Life Insurance, before his death. If a veteran were to make a similar search and look up "suicide" in the future, for example, McDaniel suggests it could trigger an ad for Stop Soldier Suicide to pop up and provide resources in the search results.Ford says the nonprofit uses machine learning, a subfield of artificial intelligence, to analyze texts and notes in order to determine sentiment or emotional tone, such as anger or desperation. He says they can also track phone usage of the deceased veterans to monitor their past sleep cycles and trace their past geo-locations."Machines can go through computations a lot faster than humans, and they can find signals that we often miss," Ford said.Since launching the Black Box Project in April 2020, Stop Soldier Suicide has received over 100 devices, Ford said. So far, he says they're seeing three patterns before most of these suicides: more anger, different sleep patterns, and social isolation.Ford's team includes Ph.D.s in clinical psychology and suicide researchers. A scientific advisory committee helps steer where and what to look for on the devices.The findings are still preliminary, according to the nonprofit, but one goal is to help the organization decide where, when, and how to target their own mental health resources, like adding more hotline staff at certain hours and ensuring calls are picked up overnight.When asked about privacy concerns of collecting data, Ford said it's something they think about daily."We don't resell the data. We don't push it out to others. We use it for our own research purposes so that we can best understand risk and then give those devices back to those families intact," Ford said.Current privacy laws do not carry on past death, meaning the next of kin typically gains new authority.Petra Oxford-Jackson, whose veteran husband Anthony died by suicide, says she gave his phone to the organization with the possibility it could save even one life."I truly believe he would have been okay with it, and it's a hard thing for a survivor to give up something so personal as his cell phone," Oxford-Jackson told ABC News.The Black Box Project received $3 million in funding from the Department of Veterans Affairs earlier this year.If you are struggling with thoughts of suicide or worried about a friend or loved one, call or text the Suicide & Crisis Lifeline at 988 for free, confidential emotional support 24 hours a day, seven days a week.。作为Meta公司通用语音翻译器（UST）项目的一部分，该项目正致力于开发实时语音到语音的翻译，以便元宇宙居民能够更容易地进行互动（读作：互相进行性骚扰）。作为这个项目的一部分，Meta的研究人员研究了福建闽南话，这是一种散居在亚洲各地的无文字语言，也是台湾地区的主流语言之一。机器学习翻译系统通常需要大量可标记的语言例子，包括书面和口语来进行训练--这正是像闽南话这样的无文字语言所不具备的。为了解决这个问题，"Meta使用语音到单元的翻译（S2UT），将输入的语音直接转换为Meta以前开创的声学单元序列，"首席执行官马克-扎克伯格在周三的一篇博文中解释说。"然后，我们从这些单元生成波形。此外，UnitY被采用为双通解码机制，第一通解码器生成相关语言（普通话）的文本，第二通解码器创建单元。

B | ""我们利用普通话作为中间语言来建立伪标签，我们首先将英语（或上面说的闽南话）语音翻译成普通话文本，然后我们再翻译成闽南话（或英语）并将其加入训练数据。"目前，该系统允许讲福建话的人与讲英语的人交谈，尽管很生硬，且该模型一次只能翻译一个完整的句子。但扎克伯格相信，这项技术最终可以应用于更多语言，并将改进到提供实时翻译的程度。扎克伯格宣布，除了Meta已经从这个项目中开源的模型和训练数据外，该公司还将发布一个基于闽南话话语料库的首个语音翻译基准系统，以及"语音矩阵，一个用Meta的创新数据挖掘技术LASER挖掘的语音翻译大料库"。这个系统将使研究人员能够创建他们自己的语音到语音翻译（S2ST）系统。
