技术文摘：富迪SAM科技让语音输入更清洁，“宣扬”免提通信

In its small-sized array microphone (after SAM) science and technology is used by Japanese DoCoMo mobile phone, science and technology of Fu Di of supplier of chip of speech input processing was held in Beijing recently " 3G of message of high qualitative sound shows martial prowess -- application of wireless communication of Fu Di science and technology and delibrate of service science and technology and reveal meeting " . Many partner of Fu Di science and technology, showed the product that uses SAW science and technology, include to be able to adorn much syncretic of money of type GPS product, whole world head adorns type intelligence communicates implement, use speech recognition and speech to hold those who accuse science and technology is portable from navigation system. Many industry public figure expresses, dismiss the heat science and technology that promotes communication and speech input to will make 3G period. Huang Yansong joined the trailblazer of EDA industry again " the revolution of interactive science and technology " in Fu Di science and technology (Fortemedia) president holds Dr. CEO Huang Yansong concurrently to express, speech inputs a revolution that will be interactive science and technology, in the past interactive give priority to with the machine, the person should go a machine in front of, and the arrival as 3G and mobile times, interactive will be it is with the person this, it is the machine follows a person to go, with speech interface emancipatory both hands, open numerous intelligence serves the development trend that is prospective industry. He emphasizes: "The user is right message of high qualitative sound and the demand that handle below all sorts of environments, abound hurried dislodge equipment the function further, make those who give mobile device adorn type platform, liberate both hands truly, promote a number the advantage of the life considerably. " and Fu Di science and technology is dedicated the research and development that handles science and technology and product at avoiding the speech that carries communication. The patent science and technology of Fu Di science and technology is small-sized array microphone (Small Array Microphone, SAM) and advanced chip make communication can absolve echo and noise interference completely. The awl state that the beam of SAM forms division skill to form person of an alignment conversation accurately is narrow beam, the sound that admits this conversation person only restrains the noise in the environment and interference at the same time. To the loud noise inside open car and rumour, according to weighing the SAM of science and technology of only Fu Di on the world science and technology can restrain this kind of noise effectively. Small-sized array microphone operates 2 complete to microphone, its span can be less than 1 centimeter. The volume that reduces a product significantly consequently and conceal array microphone easily. The acoustics echo that the science and technology of Fu Di science and technology can eliminate 65 decibel and the blame of 20 decibel are smooth noise, its are tall of the function nonlinear the communication effect that echo offsets science and technology can achieve devoid echo, even if avoid to accepted the most unmanageable alleged an organic whole carry communication system -- mix loudhailer microphone is compositive in a small carapace child Neibingjuyang sound implement have enough high volume. According to saying to look there is Fu Di only on preexistence bound the product of science and technology can solve this difficult problem. Much syncretic of global head money adorns type intelligence communicates implement, compositive blue tooth earphone + loudhailer + Sun Zhizhong of general manager of agency of Shanghai of science and technology of Fu Di of USB+SAM science and technology expresses to the reporter: "Always contain the device of microphone, move especially in the environment, SAM is operated possibly quite. Because be in mobile environment, the machine follows a person to run, noise is not controallable, want to realize clear communication, must come down noise pressing, for example computer of phone of car, video, notebook and mobile phone. " according to introducing, the product of Fu Di science and technology has been used by numerous car manufacturer, in entering notebook computer and smartphone in great quantities at present. Sun Zhizhong says, it will become future the necessary science and technology of the smartphone, "The cost that raises this science and technology at present is 5-10 dollar less than, the market can be received " . Use SAM science and technology at present, need tie-in complete directivity (Omni) microphone is added (odd directivity) Uni microphone, can use two Omni microphone directly later. In the uses science and technology of SAM of Fu Di science and technology product that shows in a few manufacturers, come from the United States to love enlighten acoustical science and technology (the love of Mvox) enlighten sound communicates king (Mvox Duo) is the most fetching attention. It is occupied saying is much syncretic of global head money adorns type intelligence communicates implement, can use as blue tooth earphone, portable car carries avoid carry communicate implement, earphone of floating conference telephone call, VoIP and avoid phone of the sound that carry spread to wait. Love enlighten sound communicates conformity of phone of Wang Jiang earphone and loudhailer is cabinet adorn the integration of type equipment is designed, and can be operated for adorning, use science and technology of SAM of Fu Di science and technology, have high quality acoustic quality, eliminate with outstanding noise and echo; Nearly 100% speech recognition are led, convenient user reachs burgeoning blue tooth equipment to undertake speech is held to having accuse and communication. In fact, the blue tooth earphone that it used SAM science and technology namely + loudhailer, can pass USB and PC join. It contains a clincher, should get off after clincher, its silent considers as earphone mode, escape the damage that suffers loudhailer in order to protect the ear of the user. Although this product looks,be like simple, research and development of software of Dan Fudi science and technology is advanced attune of Xiang Jiang of doctor of dawn of chief inspector forest says: "Should use as already earphone, should use as again loudhailer, and be inside so little space want to eliminate echo, without other at present the company can be accomplished. Because loudhailer volume is large, echo is big also, and space small, have the noise below environment of high speed shift again, involve difficult problem of a lot of science and technology. " the cost that he does not agree to disclose this product, just emphasize comparing common blue tooth earphone is a lot of more expensive. On one page 12 below one page

在其小型阵列麦克风(SAM)科技被日本DoCoMo手机采用后，语音输入措置芯片供给商富迪科技比来在北京举办了“高质音讯 3G显神威——富迪科技无线通信应用与办事科技钻研暨展示会”。富迪科技的多家合作伙伴，展示了采用SAW科技的产物，包括可钦戴式GPS产物、寰球首款多合一佩戴式智能通话器，采用语音识别和语音操控科技的便携式自导航系统。多位业界人士暗示，免提通信和语音输入将成为3G时代的热点科技。

EDA工业的开辟者黄炎松又插手到了“人机交互科技的革命”中

富迪科技(Fortemedia)董事长兼CEO博士黄炎松暗示，语音输入将是人机交互科技的一场革命，曩昔的人机交互以机械为主，人要走到机械跟前，而跟着3G和挪动时代的到来，人机交互将是以工钱本，是机械跟着人走，以语音界面解放双手、开启众多智能办事是未来工业的成长趋向。他强调：“用户对高质音讯以及各类情况下操作的需求，将促使挪动行动措施进一步丰硕性能，打造出挪动行动措施的佩戴式平台，真正解放双手，大幅晋升数字糊口的便利。”

而富迪科技则专注于免提通信的语音措置科技与产物的研发。富迪科技的专利科技小型阵列麦克风(Small Array microphone, SAM)和前进前辈的芯片使通信可完全罢黜反映和噪音干扰。SAM的波束形成科手艺切确的形成一个瞄准措辞人的锥状窄波束，只领受该措辞人的声音同时按捺情况中的噪音与干扰。对于在敞篷车内的高噪声和风声，据称世界上仅有富迪科技的SAM科手艺够有效的按捺这类噪声。小型阵列麦克风操作二个全向位麦克风，其间距可小于1厘米。因而显著的减小产物的体积而且易于暗藏阵列麦克风。富迪科技的科技能够消除65分贝的声学反映和20分贝的非安稳噪音，其高性能的非线性反映抵消科技能够达到完全无反映的通信成果，即使是对公认的最难措置的所谓一体免提通信系统——将扬声器和麦克风集成在一个小壳子内而且扬声器有足够高的音量。据称今朝世界上只有富迪科技的产物能解决这个难题。

寰球首款多合一佩戴式智能通话器，集成蓝牙耳机+扬声器+USB+SAM科技

富迪科技上海办事处总司理孙执中对记者暗示：“凡是带有麦克风的行动措施，特别是挪动情况中，SAM都可能够操作。因为在挪动情况中，机械跟着人跑，噪声不成节制，要实现清楚通信，必然要把噪声压下来，例如汽车、视频电话、笔记本电脑和手机等。”据介绍，富迪科技的产物已经被众多汽车厂商采用，今朝正大量进入笔记本电脑和智妙手机中。

孙执中介绍说，未来它将成为智妙手机的必备科技，“今朝增添这个科技的本钱为5-10美元以内，市场都能够领受”。今朝采用SAM科技，需要搭配全指向性(Omni)麦克风加上(单指向性)Uni麦克风，今后能够间接采用两个Omni麦克风。

在几家厂商展示的采用富迪科技SAM科技的产物中，来自美国爱迪声科技(Mvox)的爱迪声通话王(Mvox Duo)最惹人存眷。它据称是寰球首款多合一佩戴式智能通话器，可用作蓝牙耳机、便携式车载免提通话器、挪动会议电话、VoIP耳机和免提扬声电话等。爱迪声通话王将耳机和扬声器电话整合为一个玲珑佩戴式行动措施的整体化设计，而且可供佩戴操作，采用富迪科技SAM科技，存在高品质的音质，和卓越的噪音和回音消除；近100%语音识别率，便操纵户对现有及新兴的蓝牙行动措施进行语音操控和通信。

事实上，它就是一个采用了SAM科技的蓝牙耳机+扬声器，并可经由过程USB和PC连贯。它带有一个夹子，当取下夹子后，它默认为是耳机模式，以保护用户的耳朵免受扬声器的败坏。尽管这个产物看似简单，但富迪科技软件研发高级总监林晓博士向强调说：“既要用作耳机，又要用作扬声器，而且在如斯小的空间内要消除反映，今朝没有其它公司能够做到。因为扬声器音量大，反映也大，而且空间又小，又有高速挪动情况下的噪声，波及到良多科技难题。”他不肯透露这款产物的本钱，只是强调比通俗蓝牙耳机贵良多。
