I asked the same questions to each app to see what their answer was. Since all the apps voice recognition works in the same manner, I instead tested for how well they could research a question and return an answer.
I haven’t tested this in other languages, but American English works perfectly fine. As long as I spoke clear English and enunciated my words, my phone didn’t have any trouble recognizing my words. I’ve found the voice recognition to be quite good. All voice assistant apps rely upon the same software that comes part of all Android devices. One item that needs to be noted before looking at the individual apps is the speech recognition software itself. There are more than a few capable Siri alternatives on Android that do more than search Google. The phone system itself comes with a few voice functions like search and dictating text, but that’s by no means the limit of voice command on Android. That’s good news for Android owners with Siri envy because it means we’re not missing out on the voice assistant party. Voice assistants have been around for quite a while and in many forms. While Siri is a very well-built and high-quality voice assistant, it is by no means the first of its kind. Just ask Siri anything and she’ll come back with an answer. One of the major selling points of the new iPhone 4S is the inclusion of Siri, the new voice-operated assistant.
