WhatsApp, The four-year-old company — which helps users send text messages between all different types of mobile phones on all different carriers in every country – now rolling out push-to-talk voice messaging today for all of its apps on the iPhone, BlackBerry, Android OS, Windows Phone and Nokia, the company’s co-founder and CEO Jan Koum told AllThingsD.
The update is expected to be available to all users within 24 hours.
In the updated version of WhatsApp, the walkie-talkie-like feature will let users push to record a message, and upon letting go, the message gets sent. If you decide not to send the message, all you have to do is swipe to the left and the recording gets deleted.
There is no cap on the length of recording, and a blue microphone illustration will appear within your WhatsApp chat when a message has been played by the recipient. Another nifty feature: the volume of the recording automatically switches from speaker when held at arm’s length to soft when you bring it next to your ear.
