The textbook way isn't wrong — it's just not how anyone actually says it.
Pronouncing the vowel before M/N too pure.
In "planning", the "a" vowel before M or N raises and fronts toward [eə] — the tongue pulls up and forward, breaking the vowel into a tense glide as it anticipates the nasal. The "/æ/" vowel raises and fronts before M or N — tongue pulls up and forward, producing a tense [eə] glide (between /e/ and /ə/). Not a pure /æ/.
Releasing the final consonant with a puff of air.
In "heard", the "" is not released — the articulators get into position but hold without the burst of air. Air stops but there's no release burst — the articulators hold position.
Leaving a gap between two vowels.
Between "" and "", a brief "" glide bridges the two vowels for smooth flow. A brief glide (y or w) bridges two vowels for smooth flow.
Pronouncing every consonant in the cluster.
The "" at the end of "" is dropped before the consonant starting "" — the surrounding consonants flow directly together — common in flowing natural speech; in careful or formal speech, the sound is often kept. The /t/ or /d/ at the end is dropped — surrounding consonants flow directly.
