The speed and proficiency with which you adopt a new language usually depends on two factors that play a bigger role than the language learning software title that you use: immersion and commitment.
Commitment
Many people intend a variety of things, such as losing weight, writing a novel and learning a new language. Unfortunately, few of them are committed enough to see it through when the going gets even a little tough. As such, your level of commitment to adapting a new way of speaking will dictate a huge portion of whether you are eventually able to succeed in the area or not.
If your mindset going into language learning is just to learn it during convenient breaks in your schedule, it’s highly unlikely that you’ll learn at good pace. Often, commitment depends on an underlying motivation – find that and you’ll see massive improvements in your ability to absorb new material.
Immersion
The more you can surround yourself with the new language, the easier it becomes to integrate it into your daily speech. It is for that reason that people tend to pick up languages very fast when they’re living in an area that speaks the dialect. As such, you’ll need to find a way to invite the language into your life – whether by meeting native speakers to regularly practice with or arranging your free time so that you’re involved in learning for a good part of those.
