The Verge recently went hands on with Samsung’s new flagship Galaxy S III launched earlier this month and during its review put the device’s new Vlingo-powered “S-Voice” feature up against Siri on the iPhone 4S. Other than the striking resemblance to Siri’s UI and canned responses, the first thing we notice is Siri appears to be much quicker than S-Voice running on the Galaxy S III.
When asked “Who is the president of France”, Siri quickly asks to search the web, while S-Voice takes a little longer but comes up with the correct answer. However, in most scenarios, both Siri and S-Voice request to search the web for the majority of the same queries. You’ll also notice S-Voice has no problem keeping up with Siri when scheduling appointments, but both have some of the same issues understanding The Verge’s commands.
S Voice consistently chews up my words when I try asking it questions, although it works better when instructed to schedule an appointment or set an alarm. It can also be used as an unlocking mechanism once you pre-record a pass phrase. That adds to the face unlocking option that’s native to Android 4.0 in being frustratingly unwieldy and planted firmly within gimmick territory — more than once I was stuck repeating “hello” without any recognition from the phone.
While we don’t have all of the info on S-Voice, we know it is using voice recognition technology from Vlingo, the same as the previous Voice Commander feature for the Galaxy S II. Last December Nuance acquired Vlingo. It’s no secret Apple is currently using Nuance to power speech in Siri, and Siri co-founder Norman Winarsky told us in October that Siri originally used Vlingo, but that Nuance has by far the most “IP in speech synthesis technologies”. However, he also noted Apple could likely easily replace Nuance if something better was available.
