译成 To translate from... into
you should use a dispositive marker like 将

我将英文译成中文。 我将英文译成中文
汉语 refers to spoken Chinese; for written Chinese, use 中文

you can use preposition [由 ~ 成] or [从 ~ 成] (they both mean &quot;from ~ to&quot;)

我将哈利波特由英文译成中文 or simply &quot;我將哈利波特译成中文&quot;
you can omit '由英文' because we all know Harry Potter is originally an English novel

翻译 is the standard term for both written translation(笔译) and spoken translation (口译) -- the terms you cited. In practice, no Chinese would use those terms.
Native Chinese would not replace 翻译/译 with either 笔译 or 口译 . We can tell it is a written translation or spoken one by looking into the context. If you say a book is translated into Chinese, you don't need to say it is written; When you say the translators in a meeting translate for the heads of state, we know they are translating orally.
Interpreter is called 传译員; to interpret someone's speech in real time is called 传译 or 即时传译
