There are two series of stops and affricates in Hakka, both voiceless: tenuis /p t ts k/ and aspirated /pʰ tʰ tsʰ kʰ/.
|Nasal||/m/ 〈m〉||/n/ 〈n〉||[ɲ] 〈ng(i)〉 ~ /ŋ/ 〈ng〉*|
|Plosive||plain||/p/ 〈b〉||/t/ 〈d〉||/k/ 〈g〉||(ʔ)|
|aspirated||/pʰ/ 〈p〉||/tʰ/ 〈t〉||/kʰ/ 〈k〉|
|Affricate||plain||/ts/ 〈z〉 ~ [tɕ] 〈j(i)〉*|
|aspirated||/tsʰ/ 〈c〉 ~ [tɕʰ] 〈q(i)〉*|
|Fricative||/f/ 〈f〉||/s/ 〈s〉 ~ [ɕ] 〈x(i)〉*||/h/ 〈h〉|
|Approximant||/ʋ/ 〈v〉||/l/ 〈l〉||/j/ 〈y〉|
Moiyen Hakka has seven vowels, [i ɨ ɛ a ə ɔ u], that are romanised as i, ê, a, e, o and u,[clarification needed] respectively. The palatisation medial ([j]) is represented by i and the labialisation medial ([w]) is represented as u.
Moreover, Hakka rimes exhibits the final consonants found in Middle Chinese, namely [m, n, ŋ, p, t, k] which are romanised as m, n, ng, b, d, and g respectively in the official Moiyen romanisation.

Moiyen has four tones, which are reduced to two in a checked syllable. The Middle Chinese fully voiced initial syllables became aspirated voiceless initial syllable in Hakka. Before that happened, the four Middle Chinese 'tones', ping, shang, qu, ru, underwent a voicing split in the case of ping and ru, giving the dialect six tones in traditional accounts.
|Tone number||Tone name||Hanzi||Tone letters||number||English|
|5||yin ru||陰入||˩ʔ||1||low checked|
|6||yang ru||陽入||˥ʔ||5||high checked|
These so-called yin-yang tonal splittings developed mainly as a consequence of the type of initial a Chinese syllable had during the Middle Chinese stage in the development of Chinese languages, with voiceless initial syllables [p- t- k-] tending to become of the yin type, and the voiced initial syllables [b- d- ɡ-] developing into the yang type. In modern Moiyen Hakka however, part of the Yin Ping tone characters have sonorant initials [m n ŋ l] originally from the Middle Chinese Shang tone syllables and fully voiced Middle Chinese Qu tone characters, so the voiced/voiceless distinction should be taken only as a rule of thumb.
- Entering tone
Hakka preserves all of the entering tones of Middle Chinese and it is split into two registers. Meixian has the following:
- 陰入 [ ˩ ] a low pitched checked tone
- 陽入 [ ˥ ] a high pitched checked tone
Middle Chinese entering tone syllables ending in [k] whose vowel clusters have become front high vowels like [i] and [ɛ] shifts to syllables with [t] finals in modern Hakka as seen in the following table.

For Moiyen Hakka, the yin ping and qu tone characters exhibit sandhi when the following character has a lower pitch. The pitch of the yin ping tone changes from ˦ (44) to ˧˥ (35) when sandhi occurs. Similarly, the qu tone changes from ˥˧ (53) to ˦ (55) under sandhi. These are shown in red in the following table.
|+ ˦ Yin Ping||+ ˩ Yang Ping||+ ˧˩ Shang||+ ˥˧ Qu||+ ˩ʔ Yin Ru||+ ˥ʔ YangRu||+ Neutral|

|˥˧ Qu +||˥˧.˦||˥.˩||˥.˧˩||˥.˥˧||˥.˩ʔ||˥˧.˥ʔ||˥.˧|
The neutral tone occurs in some postfixes. It has a mid pitch.
