Ever since Samsung announced the Samsung Galaxy S3 with S Voice, which by the way stands for Samsung Voice. Everyone was left with the question if this would ever be available for current S devices. Samsung did say this was part of the new features for the upcoming Galaxy S3. Shortly after it didn't take long for the community to get their hands on the S Voice apk and release it in the wild for download and was able to work in other devices that are not Samsung S series phones.
You will see how will the unofficial release of the S Voice is working on the Galaxy Note, which after testing for about a week is working great. I am able to dial out, look for services, add calendar appointments, have it read my text, send out memo and many other features that have all been working great on the Galaxy Note. Keep in mind this application was intended for the Galaxy S3. Your results may vary, so you might want to give it a shot.
