Lateral plosion
A plosive (/p/, /b/, /t/, /d/, /k/, /g/) preceding the lateral sonant / l /
either within a word or at a word junction becomes laterally exploded, i.e. it
has its explosion during / l /, the air stream passing at the sides of the tongue.
This phenomenon is known as lateral plosion (partial regressive
assimilation).
Special care should be taken to pronounce the English sound
combinations / pl, bl, tl, dl, kl, gl/ with "lateral plosion". This can be
achieved by practicing the pronunciation of these combinations without
removing the tip of the tongue from the alveoli after /p, b, t, d, k, g /
respectively.
Examples:
[pl]
please
apple
[bl]
bleak
[tl]
little
mostly
clothes
horrible
[dl]
candle
[kl]
clean
table
badly
[gl]
glad
wriggle
Examples from «The stranger»:

But can you help me, please?
please (/p/ losses its plosion under the
influence of /l/)

Yod Coalescence
Yod coalescence is a special kind of reciprocal assimilation.
In yod coalescence, both consonants influence each other and fuse
together to form a new one, an affricate.
The Yod coalescence occurs when we pronounce the sound /t/ or /d/
which come before a word that starts with the sound /j/, then these two
sounds can come together and change to the affricates /ʧ/ or /dʒ/:
/t/ + /j/ = /tʃ/
Did you like the present I got you for your
birthday?
Won't you come to the party?
But use your head!
Last year
/ ɡɒtʃə /
/ wəʊntʃə /
/ bətʃu:z /
/ lɑ:stʃɪə /
/d/ + /j/ = / dʒ/
Could you help me?
Would yours work?

Examples from the song «Because I Had You» by Shawn Mendes:
yod coalescence
Should've told you not to go
told you / təʊldʒə /
Because I had, because I had you
But I can tell that you're happy
I wish I had you
had you / hædʒə /
that you're /ðætʃə /
had you / hædʒə /
