Here are the highlights:

1. MTL is a phonetically consistent, multi-syllable orthography based on POJ. MTL is sandhi-aware, meaning the written form of a multi-syllable word reflects the tone of the front syllable after Tone Sandhi has applied. This overcames the homonym ambiguity in character-based writing system. When a lighter, and weaker tone during speaking is needed, it is marked by the backquote '`' instead of double dashes ("--") in POJ and KIP. Note: A less well-known system named TOJ is POJ-based system without dashes. Unlike MTL, TOJ is not sandhi-aware.

   

2. Tone 1 is marked by 'f' (e.g., of - dark, black ). Exception: After 'i', Tone 1 is written as 'y' (instead of if). After 'u', Tone 1 is written as 'w' (instead of uf)."

3. Tone 2 is marked by 'r'. (e.g., or - dig as óu in KIP) But for some vowels/diphthongs, it uses specific convention to enhance:

   
     air	ae	(as ái in POJ)
     ir	ie	(as í  in POJ)
     ur	uo	(as ú  in POJ)
     er	ea	(as é  in POJ)
     aur	ao	(as áu in POJ)
   

4. Tone 3 is marked by 'x' (e.g., ox - dislike; as òuin POJ, and òo in KIP)

5. For Tone 5, it duplicates the vowel. E.g. 'oo' instead of 'ôu' in POJ 'ôo' in KIP. For ø in tone 5, it is written as 'øo' instead of 'øø' - mainly for faster typing since 'ø' takes extra strokes. eg: 'gøo' (geese) as 'gô' in POJ/KIP, 'hør' (good) as 'hó' in POJ/ KIP. It is used to distinguish from 'o'. E.g. 'hor' (tiger) as 'hóu' and 'hóo' in POJ and KIP respectively.

   

6. For Tone 7, no tone indicators is used. (e.g., oe as ōe in POJ, and uē in KIP)

7. For short tones (Tone 8 and 4), these letters - 'h', 'p', 't', 'k', 'q', 'b', 'd', and 'g' - serve as tone indicators. Those 8 characters might be consonants, except 'd' and 'q', when used as a leading character of a syllable.

8. Special Consonants and Vowels

   Concept	             MTL Symbol	    POJ/KIP Equivalent	    Notes
   
   Front Nasal Vowel	v(e.g., va)  āⁿ (POJ), ānn (KIP)	   Represents the unique nasalized vowel. E.g., va.
   
   Special Vowel	        ø	    (Often ô or o͘ in POJ)  Distinguishes sounds. 
   
   Velar Nasal	        eng	    -ing (KIP)	           The phoneme is consistently written as -eng in MTL.
   
   General Vowel          -ue (KIP)   The phoneme is consistently written as -oe in MTL.
   

   Using 'v' makes it consistent in writing. E.g. 'gvor' (i.e., 5) uses 'v' for nasal instead of 'ng' in POJ and KIP (ngó, ngóu).

9. Abrutp tone

   Tone Level (POJ Equivalent) 	Coda Markers	Example
   
   High Short (Tone 8, like a̍h)	h, p, t, k	ah, ap, at, ak
   
   Low Short  (Tone 4, like ah)	q, b, d, g	aq, ab, ad, ag
   

10. The Sibilant Split (Consonant Initials)

    The POJ/KIP initials 'ch-' and 'ts' are split based on the following vowel:

    'c': Used before i (e.g., ci for chi in POJ).
    'z': Used before a, e, o, u. (e.g., ze → che in POJ and tse in KIP)

    
    Main differences between POJ and Tâi-lô:
    
    ch → ts (e.g., chū → tsū, chhî → tshî)
    chh → tsh (e.g., chhân → tshân, chhōe → tshuē)
    ⁿ → nn (e.g., iⁿ → inn, saⁿ → sann)
    oa → ua (e.g., poe → pue, sòaⁿ → suànn)
    oe → ue (e.g., hoe → hue)
    o· → oo (e.g., lō· → lōo)
    goán → guán
