The announcement was made during this week's 2015 Mobile World Congress trade show. Telefónica said
Telefónica's Movistar TV Go service for Windows Phone 8.1 will enable Telefónica users to enjoy their favourite TV content, both linear and on-demand – just by speaking into the phone. The unique Cortana technology is integrated for the first time in Telefónica's worldwide commercial video service as a differentiating and innovative experience for Windows Phone users who will be able to search for content through the natural speech interface.
Telefónica aims to launch the final commercial version of the Movistar TV Go app on Windows Phone 8.1 shortly after the MWC. Meanwhile, it will be tested in a Spanish language "beta" version to ensure perfect consumer interaction through Cortana natural speech. It will be the first time that Cortana for Spanish language is integrated in a worldwide commercial service, positioning Telefónica as a key partner for Microsoft to develop this kind of innovative experience in a worldwide footprint.
The Windows Phone 8.1 version will launch first in Spain and then later in Latin American countries.
