Everyone's English foundation and oral English level are different, and everyone needs different time. There is no unified specific figure.

There are usually two problems in poor spoken English:

1, the phonetic foundation is not enough; 2. The expression is not accumulated enough.

Language is a process from input to output. Listening and reading belong to input, while speaking and writing belong to output. Without a lot of listening and reading input, your oral English will be passive and unable to improve effectively.

If you want to learn spoken English well, the surrounding environment is very important. Because only in English environment can you feel English more frequently. Full-time English study can also help you learn English more systematically. Full-time English learning is different from other forms of English teaching. It is a relatively comprehensive knowledge.
