Intention

[MearazAhmed]

Is there a spoken intention or "niyaat". Some people say there is others say no.

[Little_Lion]

To my knowledge, there is no evidence that the Prophet (pbuh) or his Companions ever spoke the niyat aloud. Saying it from the heart is sufficient.

Allah forgive me if I am mistaken, and someone please correct me if I am!

[fhmn63]

Making Niyah is important ,Pronouncing it is not necessary, so far I know.

[Huzaifah ibn Adam]

Imaam al-Kaasaani رحمة الله عليه, one of the giants of the Hanafi Madh-hab, mentions in Badaa'i`-us-Sanaa'i` fee Tarteeb-ish-Sharaa'i` that the place of the intention (Niyyah) is the heart; hence, even if no verbal intention is made, your Niyyah is valid. However, it is Mustahabb (recommended) to make the intention verbally along with making it in the heart.
