上周中國(guó)下載次數(shù)最多的app榜單上,，不是以往的游戲或短視頻應(yīng)用，而是新的即時(shí)通訊軟件——子彈短信,。這款app令人吃驚地登上下載排行榜首,，意味著國(guó)民通訊軟件微信遇到了罕見(jiàn)的挑戰(zhàn),。

子彈短信起名源于快捷，這款app擅長(zhǎng)即時(shí)語(yǔ)音通信,，即用一連串短音頻進(jìn)行溝通,。這種模式在西方尚未流行，但在中國(guó)是常態(tài),。

2012年,，上線不久的微信讓語(yǔ)音通信流行起來(lái)，但限制一直比較多,。比如,，微信上的語(yǔ)音信息只能整段播放。如果接收方?jīng)]聽(tīng)清楚語(yǔ)音末尾某個(gè)關(guān)鍵詞,，就得從頭再聽(tīng)一遍,。另外，發(fā)語(yǔ)音后如果忘了某個(gè)重要細(xì)節(jié),，想搜索已發(fā)送信息或者查看已發(fā)送內(nèi)容很困難,。

子彈短信聰明地解決了這兩個(gè)難題。首先,，用戶(hù)可以拖拽音頻文件進(jìn)度條,，從任何一點(diǎn)重新播放。這項(xiàng)改進(jìn)其實(shí)很簡(jiǎn)單,，微信卻一直沒(méi)有實(shí)現(xiàn),，讓人有點(diǎn)意外（就連Facebook的WhatsApp都有音頻短信拖拽播放功能，而且WhatsApp是在微信之后才推出語(yǔ)音功能）,。

子彈短信解決第二個(gè)問(wèn)題的辦法更出色,，同樣算不上多獨(dú)特。軟件能將語(yǔ)音短信同步轉(zhuǎn)換成文字短信同時(shí)發(fā)出,，從而為對(duì)話(huà)留下了可見(jiàn)記錄,。實(shí)現(xiàn)該功能的是中國(guó)人工智能翻譯公司科大訊飛。去年,，《麻省理工科技評(píng)論》（MIT Technology Review）將科大訊飛譽(yù)為中國(guó)“最聰明的公司”,。微信也有將語(yǔ)音轉(zhuǎn)換成文字的功能，但用戶(hù)必須逐條選擇點(diǎn)擊轉(zhuǎn)換,。子彈短信簡(jiǎn)化了操作,，整體而言用戶(hù)體驗(yàn)更好，而這可能正是人們對(duì)子彈短信主要投資人——錘子科技的期望,。

錘子科技（英文為Smartisan,，由“smart（聰明）”和“artisan（工匠）”兩個(gè)單詞組合而成）成立于2012年，創(chuàng)始人羅永浩曾在紐交所上市公司新東方擔(dān)任英語(yǔ)教師。羅永浩因?yàn)橹v課風(fēng)格幽默讓成為網(wǎng)絡(luò)紅人,，2011年在西門(mén)子北京總部外砸西門(mén)子冰箱而出名,。當(dāng)時(shí)羅永浩認(rèn)為西門(mén)子冰箱有設(shè)計(jì)缺陷，所以砸冰箱維權(quán),。

如今錘子科技造的是智能手機(jī),，不是冰箱。手機(jī)銷(xiāo)量或許有點(diǎn)慘淡,，僅占2017年中國(guó)智能手機(jī)市場(chǎng)的1%,，但聚集了一批熱情的追隨者。今年5月,，2.3萬(wàn)粉絲云集鳥(niǎo)巢,，也就是2008年北京奧運(yùn)會(huì)主體育場(chǎng)，參加錘子科技堅(jiān)果R1手機(jī)發(fā)布會(huì),，門(mén)票最貴的達(dá)140美元,。羅永浩邀請(qǐng)吉尼斯世界紀(jì)錄大全到場(chǎng)見(jiàn)證盛會(huì)，吉尼斯紀(jì)錄稱(chēng)之為迄今為止“觀眾人數(shù)最多的科技產(chǎn)品發(fā)布會(huì)”,。

羅永浩明確表示，子彈短信并不是要擊敗騰訊,。他在微博上寫(xiě)道：“子彈短信沒(méi)有挑戰(zhàn)微信,，而是做一個(gè)在意溝通效率的人群的細(xì)分領(lǐng)域而已”。但8月20日上線的子彈短信已經(jīng)開(kāi)始多元化布局,，業(yè)務(wù)擴(kuò)展到即時(shí)通信以外,。

子彈短信app還有新聞推送功能——子彈新聞，設(shè)計(jì)上類(lèi)似估值數(shù)十億美元的新聞推薦引擎今日頭條,。子彈新聞把騰訊作為新聞源之一,，毫不意外騰訊表示反對(duì)。羅永浩還暗示,，子彈短信很快就會(huì)接入支付寶,，也就是騰訊在移動(dòng)支付領(lǐng)域的主要對(duì)手。

不過(guò),，支付寶還沒(méi)有表示將和子彈短信正式合作,。阿里巴巴旗下負(fù)責(zé)管理支付寶的螞蟻金服也只是說(shuō)：“支付寶歡迎所有具備資質(zhì)的公司將支付寶接入其產(chǎn)品和服務(wù)中?！蔽浵伣鸱幢硎局Ц秾殞⒔尤胱訌椂绦?，而此舉可能是對(duì)付微信最有效的手段。

由于子彈短信內(nèi)部不具備多種業(yè)務(wù)生態(tài)系統(tǒng),，不太可能分流微信的用戶(hù),。新app的賣(mài)點(diǎn)完全基于用戶(hù)體驗(yàn)，而用戶(hù)體驗(yàn)很容易模仿。目前來(lái)看,，子彈短信只是一次示警,，刺激微信改善語(yǔ)音短信服務(wù)體驗(yàn)，或許還提供了明確的方向,。（財(cái)富中文網(wǎng)）

This week, China’s most downloaded app wasn’t a game or a short-video app like normal but a new messaging service called Bullet. The app’s startling assent to the top marks a rare challenge to Tencent’s WeChat—China’s go-to choice for messaging.

Bullet, so called for the swiftness of its service, specializes in instant voice messaging, whereby users communicate through a rally of short audio clips. That method hasn’t caught on in the West, but in China, it’s the norm.

WeChat popularized that style of communication during its early days, in 2012, but its system has always been comparably limited. For one, WeChat only allows voice messages to be played in full, so if a listener misses a vital word towards the end of a clip, they have to start over from the beginning. Also, sending audio files makes it harder to scan through previous messages and check what’s already been said, in case you’ve forgotten an important detail.

Bullet has smartly solved both of these problems. Firstly, it allows users to scrub through audio files and start playback at any point—a simple enough fix that it’s surprising WeChat hasn’t introduced this function itself. (Scrubbing through voice messages is even a feature on Facebook-owned WhatsApp, which introduced voice messages after WeChat did.)

Bullet’s second solution is more impressive, but also not inimitable. The app instantly transcribes audio into a text message and sends the text along with the voice clip, leaving a visible record of the conversation. That magic is powered by iFlyTek, a local AI translation wizard that MIT Technology Review ranked as the “smartest company” in China last year.

WeChat has a transcription feature, too, but the user has to choose to transcribe each message. Bullet has streamlined the process and generally provides a greater user experience, which is something you would expect of the messaging app’s key investor, Smartisan.

Smartisan (a portmanteau of “smart” and “artisan”) was founded in 2012 by Luo Yonghao, a former English teacher at New York-listed New Oriental. Luo gathered popularity online for his humorous classes, but he gained notoriety in 2011 for smashing Siemens refrigerators outside of the German brand’s Beijing headquarters. The demonstration was a protest of what Luo believed was Siemens’ shoddy design.

But Smartisan doesn’t make fridges, it makes smartphones. Sales might be slight—accounting for just 1% of the Chinese smartphone market in 2017—but the company has an ardent following. In May this year, 23,000 fans flocked to the Bird’s Nest Stadium in Beijing, home of the 2008 Summer Olympics, to attend the launch of the phone maker’s R1 model, paying up to $140 for entry. According to Guinness World Records, which Luo had invited to witness the spectacle, it was the “l(fā)argest audience for a technology product launch” to date.

Luo has stated that Bullet is not an attempt to topple Tencent. Writing on Weibo, the Chinese version of Twitter, Luo said, “We are not challenging WeChat. We are creating a niche product for people who care about the efficiency of communication.” But Bullet, which was launched on August 20, has already diversified its service beyond messaging.

The app runs a news feed, which is similar in design to that of multi-billion-dollar news aggregator, Toutiao. The newsfeed featured content skimmed from Tencent News until, unsurprisingly, Tencent told Bullet to stop. Luo has also hinted that the app will soon include payment services provided by Alipay, Tencent’s arch-rival in the mobile payments war.

But Alipay hasn’t suggested it would form an official partnership with Bullet. Ant Financial, the Alibaba affiliate that manages Alipay, has simply said, “Alipay welcomes all eligible businesses to incorporate Alipay solutions into their products and services.” It hasn’t suggested Bullet will feature within the Alipay app, where it would be the most effective as a weapon against WeChat.

Without a rich ecosystem of services to pad it out, Bullet’s app is unlikely to divert followers away from WeChat. The upstart’s key selling points are all based on user experience, which can be easily emulated. For now, Bullet is just a shot across the bow, providing WeChat with an incentive—and perhaps a guide—to improve its own audio messaging service.
