What are effective ways of improving my level of spoken French?

The most effective way of improving your level of spoken French is to practise. Listening to native French speakers in podcasts, films, TV shows and YouTube videos can be extremely beneficial, as you can familiarise yourself with the way they speak, and work towards emulating this. Improving your written French and overall fluency will help too, as you will speak faster and with fewer mistakes. Take your time, as this is an ongoing process. It is important to try your best and have fun with it!
