The phonics concept
Understanding the WH Digraph
The wh digraph is one of the earliest digraphs Foundation students encounter because wh question words appear in decodable texts from the very first weeks of reading instruction. Understanding that wh represents /w/ in Australian English — and that who is the key exception — gives students a reliable decoding and spelling strategy for a set of extremely high-frequency words.
wh represents /w/ in Australian English
In Australian English, the digraph wh represents the single phoneme /w/ in nearly all words. The question words what, where, when, which, and why all begin with /w/ in authentic Australian speech. This is different from some American dialects, where wh can be pronounced as a distinct /hw/ sound. For Australian classrooms, teaching wh as /w/ is both phonemically accurate and curriculum-aligned. The digraph appears in some of the most frequent words in the English language, making it a high priority for early phonics instruction.
The who exception
The most important exception to wh=/w/ is the word who and its derivatives: whose, whom, and whole. In these words, wh represents /h/ rather than /w/. Students encounter who very early in their reading journey, often as a sight word before formal wh digraph instruction begins. Flagging who explicitly as an exception prevents confusion when the wh=/w/ rule is introduced. A simple classroom anchor is: who sounds like it starts with h because it does. All other common wh words follow the /w/ rule.
wh vs w: a spelling distinction, not a sound distinction
Because wh and w represent the same phoneme /w/ in Australian English, students cannot distinguish them by listening alone. This means the choice between wh and w is a spelling challenge, not a decoding challenge. The most useful classroom strategy is to teach that wh is used almost exclusively in question words and a small set of fixed spellings (wheel, whisper, whale). Teaching students to associate wh with question words gives them a reliable semantic anchor for correct spelling without requiring phonemic discrimination between two identical sounds.
wh question words as high-frequency decodables
The wh question words (what, where, when, which, why, who) appear in virtually every year level of primary school reading and writing. They are high-frequency function words that anchor comprehension and composition. Teaching students to decode these words confidently using the wh=/w/ rule eliminates a significant source of reading hesitation. Minimal pair practice with witch/which and wear/where reinforces the grapheme-phoneme mapping while simultaneously building awareness that spelling differences can carry meaning differences, a key insight for the phonics-to-writing bridge.

WH Question Words and Their Phonemes
Five of the six core wh question words use /w/. Only who uses /h/. Teaching this distinction early prevents the most common wh confusion in student writing and decoding.

How SoundSnapp Supports WH Digraph Teaching
See & Tap Mode
Whole-class wh digraph work on the board. Students see the word, then tap each phoneme tile in sequence. For wh words, the first tap produces the Australian /w/ phoneme — reinforcing that wh and w represent the same sound. No logins, any device, free forever.
- wh question word phoneme tapping
- wh vs w minimal pair contrasting
- Australian-accented /w/ audio for every word
- who exception clearly flagged
- No logins or setup required
Assessment Mode
Tracks which students have secured the wh=/w/ mapping and identifies those still treating wh as an unknown. Surfaces the who exception separately so teachers know which students need targeted follow-up.

Australian Curriculum alignment
WH Digraph in the Australian Curriculum
The wh digraph is introduced in the Foundation year alongside other common digraphs. Its high frequency in question words means it appears in both the phonics strand and the language/literacy strand of the Australian Curriculum: English.
Foundation
wh introduced with question words
Students learn wh in the context of what, where, when, which, and why. These words appear in decodable texts very early, so early wh instruction has immediate transfer to reading and composition tasks.
Year 1–2
Consolidation and exception teaching
Year 1 consolidates the wh=/w/ rule and introduces the who exception explicitly. Year 2 extends to less common wh words (whisper, wheel, whale) and to wh vs w minimal pair spelling work.
SoundSnapp alignment
Australian /w/ audio, not American /hw/
SoundSnapp models every wh word with authentic Australian-accented audio. The /hw/ phoneme does not exist in Australian English, so American TTS voices give students the wrong phoneme target. SoundSnapp's ElevenLabs Australian voice ensures correct phoneme modelling.

Questions & answers
Frequently Asked Questions
Why does wh make the /w/ sound?
In Australian English, the digraph wh represents the phoneme /w/ in almost all words. This is a result of historical sound change: in Old English, wh was pronounced as a distinct /hw/ sound (a voiceless labial-velar fricative), but this phoneme merged with /w/ in most English dialects over several centuries. In Australian English, which developed from Southern British English varieties, the /hw/ phoneme no longer exists. Words such as what, where, when, which, and why are all pronounced with a straightforward /w/ at the beginning. Teaching wh as /w/ is therefore phonemically accurate for Australian students and reflects their actual spoken language.
Is 'who' a wh word?
Yes, who is a wh question word, but it is also the most important exception to the wh=/w/ rule. In who, who, whose, and whole, the wh represents the phoneme /h/ rather than /w/. This is a historical irregularity: the word derives from Old English hwa, where the h-sound was retained while the w was lost. Students need to learn who, whose, whole, and whom as exceptions. The easiest classroom explanation is that these words sound like they begin with h, not w. For most Foundation to Year 2 students, who is encountered very early as a sight word, so flagging it explicitly as a wh exception prevents confusion when the wh=/w/ rule is introduced.
How do I teach wh versus w to my students?
The most effective approach uses minimal pair contrasting: pairs of words that differ only in their initial grapheme (witch/which, wear/where, wine/whine, wales/whales). Present both words auditorally and ask students to identify what they hear at the beginning. Because wh and w represent the same phoneme /w/ in Australian English, students will hear no difference in sound. This is actually the key teaching point: these two graphemes represent the same sound in Australian English, so the distinction is a spelling distinction, not a sound distinction. Students who understand this are less likely to confuse wh and w in writing. Contextual clues, particularly that wh question words signal questions, help students choose the correct spelling.
Why not teach wh as /hw/ like some American programmes?
Teaching wh as /hw/ is phonemically inaccurate for Australian students and should be avoided. The /hw/ phoneme exists in some American English dialects (particularly in the American South and parts of Scotland), but it does not exist in Australian English. Teaching students to produce a sound they do not use in their spoken language embeds an incorrect phoneme target and can cause confusion when students encounter native Australian speech. Australian curriculum materials and Australian phonics programmes consistently treat wh as representing /w/. Always use Australian-accented audio sources when modelling the wh digraph to ensure the phoneme target matches the sounds students hear in their daily lives.
