變音後語意不變 所以它們是Allophones of the same phoneme.
(k) (s) (t) are initial sounds if (k s t) are not in intial sounds, they should change into voiced sounds.
可是1 號.3號 .7號10號 12號也是在這樣的情況條件下 為什麼就不用變音呢??

sequential voicing cuts in when two voiceliess consonants are tacked on with another voiceless one. for example, morphemen six " Ka Ta, K and T are voicless consonant; therefore, when the third consonant, Te got added on, the second cnsonant Ka turns into voiced consonant Ga. case 1,3,7,10,and 12 contains one set of voiced consonants and what is why Redaku spares.

This is due to " RENDAKU".
Here is what i got for you. they proposed some facts that makes the wonderings
you just mentioned the above. Hope this works for you. Good luck. Also,
please do not miss the other links" CONSONANT MUTATION" for further info....
plese see the links for complete texts. the text below is for temp use only.
Rendaku (連濁?, lit. "sequential voicing") is a phenomenon in Japanese morphophonology that governs the voicing of the initial consonant of the non-initial portion of a compound or prefixed word. In modern Japanese, Rendaku is common but unpredictable. It is also known as "sequential voicing".
Rendaku can be seen in the following:
[hito] + [hito] > [hitobito] ("person" + "person" → "people")
[te] + [kami] > [tegami] ("hand" + "paper" → "letter")

 Properties blocking rendaku
Research into defining the range of situations affected by rendaku has largely been limited to finding circumstances which cause the phenomenon not to manifest itself.
 Lyman's Law
The most famous of the conditions affecting rendaku is known as Lyman's Law, which stated that rendaku does not occur if the second consonant of the second element is a voiced obstruent. This was later modified to state that rendaku does not occur when the second element of the compound contains a voiced obstruent in any position (see third example below). This is considered to be one of the most fundamental of the rules governing rendaku.

like what the link says, the Rendaku is common but inpredictable, especially when it comes to the geographical or persons' names.
