Among the most annoying headaches associated with cable cutting and the era of on-demand streaming video entertainment is the maintenance of multiple account signups for services such as Netflix, Hulu, and the like.  This will undoubtedly only get more annoying as new streaming services from companies like Apple, Disney and WarnerMedia come into the picture. This is something Roku has tried as part of a series of optimizations associated with the launched Roku OS 9.1 update rollout for users today.
In a blog post from the company, Roku CEO Ilya Asnis said the new features include language enhancements, Roku search updates, an updated guest mode, and a particularly useful automatic account linking feature. 1
As far as the new update is concerned, the new voice search makes it easier to dive content faster. Now, if you're looking for your voice, movies and TV shows available on The Roku Channel, in addition to those available in the Roku Premium Subscription services, will automatically play most of the time. If automatic voice-over playback is not available for any reason, Roku indicates that "impartial search results" are displayed after the price. Other channels are likely to support this feature soon.
Speaking Thanks to the Language With the new update, you can also say things like "Replay" to go back a few seconds. You can now verbally turn closed captions on and off.
In the function formerly known as auto logout mode, guests can log in to subscription channels using their own login credentials. It is useful if, for example, you have a friend with you. The OS update now allows you to enable or disable this feature for specific Roku devices that you own. It can be managed through the My Connected Devices section of the My Account page on Roku.com. You can also use this to log off a guest from a device if they may leave earlier.
Per Ilya, the software update is available today on selected Roku streaming players and is expected to be available to all supported players in the coming weeks. In addition, Roku TV models are expected to receive the update this summer.
