If you are starting out with Spanish, our first piece of advice is quite simple: take it easy! You can't learn to speak a foreign language fluently overnight, but if you're patient and constant, you'll soon feel you're progressing.
Listen, listen & listen
No one starts to speak a language without listening first. That's how we all learnt our mother language when we were babies. We just took out time and exposed ourselves to oral language for months before starting to utter our first few words.
So listen to as much authentic Spanish as possible. Our videos and podcasts will help you here.
Listen & repeat
Yes, constant repetition is also a good practice. After all, babies also do that everyday, until they refine their pronunciation. They end up being fluent speakers, so you'd better follow their example.
