1.字节跳动的音乐流媒体应用Resso在印度正式启动

TikTok, the hugely popular social media app, found a lot of early traction by giving users a way to create funny lip-synced versions of clips from well-known songs and then share them with friends (its predecessor in the West was even called Musically). Now at long last, TikTok’s owner, China’s ByteDance,  is doubling down on the music connection with the release of its first standalone full music streaming app, starting first in India.

Today, the company is launching Resso, which describes itself as a “social music streaming app”: users are encouraged to share lyrics, comments and other user-generated content with each other, alongside full-length tracks of music that they can consume and also share with others. And the music begins to auto-play as soon as you open the app.

2.Android上的Google Assistant（谷歌助手）现在可以为用户朗读网页内容

Just a few weeks back at CES, Google gave a sneak peek of a feature that would let your Android devices read entire web pages aloud to you — perfect for when you don’t have a hand free to scroll but still need to catch up on some text, or for when you just don’t feel like looking at your screen anymore. You’d say, “Hey Google,  read this page,” and they’d spin up Google Assistant’s neural networks to generate a pretty dang spot-on reading of it.

3.Twitter推出时效24小时的临时推文“Fleets”功能

Twitter is testing its own version of Stories. The company announced today it will begin to trial a new sharing format called “Fleets,” starting in Brazil, which will let users post ephemeral content to its social network for the first time. Unlike Tweets, Twitter’s new Fleets can’t receive Likes, Replies or Retweets. And they’ll disappear entirely after 24 hours.

Fleets aren’t non-public, to be clear; they’re just a little less accessible. You could visit someone’s public Twitter profile and tap to view their Fleets even if you don’t follow them. But their Fleet won’t circulate Twitter’s network, show up in Search or Moments, and it can’t be embedded on an external website.

4.Messenger的Mac版本已上线
