Spoken English

Hello,
English is best for learning English.
You can also try the newest language app ELSA Speak (www.elsaspeak.com) that uses AI to help people improve their pronunciation, as referred to by Forbes. It will analyze your speech and pinpoint exactly what your errors are (which vowel or consonant or stress) and give you recommendations on how to move your tongue or lips differently to correct those errors.

Dear,
In terms of atmosphere, opportunities, events and students participation, I would recommend British council. They have a well-equipped library.
All the best.

To improve your spoken English, you should read newspaper, collect the vocabulary, find the meaning, learn it and even use it. You should also do loud reading. This way, you will be able to get the fluency. If possible, join a spoken English class.
