たくさん話す

You usually place たくさん right before the verb 話す. It acts like an adverb here. If you want to be polite, change it to たくさん話します. To talk about the past, use たくさん話しました. It is a very flexible building block for your Japanese. You will hear it in almost every casual conversation.

Use this when you meet a friend after a long time. It is perfect for describing a great first date. You can also use it to describe a chatty coworker. Use it when you want to encourage someone to open up. "Please, talk a lot!" sounds very welcoming in Japanese. It’s great for texting after a long phone call too.

Avoid this in extremely formal business presentations. In those cases, use 詳しく説明する (explain in detail). Don't use it if the "talking" is actually a one-sided lecture. It implies a back-and-forth flow of words. Also, if someone is being too loud, this phrase might be too soft. There are harsher words for "noisy."

Japan is often seen as a culture of silence. However, たくさん話す is highly valued in close relationships. It signifies trust and "kokoro no kyori" (heart distance). When you talk a lot with someone, you are becoming "nakayoshi" (close friends). It breaks the formal barrier of Japanese society. Sharing stories is the best way to build a bond here.

You might hear いっぱい話す (ippai hanasu) in very casual settings. いっぱい is a bit more "bubbly" and cute. If you want to say "talk more," use もっとたくさん話す. For a very polite version, use たくさんお話しします. Each variation changes the flavor but keeps the heart of the meaning.
