The phoneme /n/ is pronounced in the same way in English and Spanish, so it doesn’t give any trouble.
Spelling: n (now, net), ne (phone, nine), nn (dinner, channel), kn (knife, knot), gn (sign, gnat). Exceptional spelling: pn (pneumatic)
As it happened with the /m/, the sound /n/ is very simple: do it as you do it in Spanish. Only, here again, it’s interesting to have a look at the spelling because some consonants become silent when they come next to an n.
Remember three cases where you only have to pronounce an /n/.
1. When the n is doubled.
2. When a word starts with the consonants kn.
3. When you find gn at the beginning or end of words.
And here you have a native speaker pronouncing the phoneme /n/ several times.
