Sound-form annotation (IPS notation) is a kind of direct inline phonetic notation: without changing the spelling of a word, it distinguishes different readings of a word by marking symbols above the word’s vowel letters and a few consonant letters. It is more concise than IPA symbols and other respelling symbols.
The IPSM Approach divides a word’s main vowel pronunciation, from “strong” to “weak,” into four rhythms: open syllable, closed syllable, light syllable, and weak syllable. The open syllable is marked with a horizontal line (─), the closed syllable is unmarked (∅), the light syllable is marked with a dot (⦁), and the weak syllable is marked with a ring (○).
IPS notation and IPA correspond one-to-one: a word’s IPA can be converted into IPS, and vice versa. If the reader has not yet mastered IPA, this does not affect the learning of IPS; if the reader has already mastered IPA, it not only helps in learning IPS but also leads to a better understanding of IPA.
Compared with IPA, IPS is created according to the pronunciation rules of words and is concise and clear; through its subtle influence one masters the pronunciation rules of words, so that phonetic annotation is no longer needed.
A second-grade primary school student who has mastered the 26 English letters and Chinese pinyin can learn IPS notation.

Light Sound
| Light sound | [ ȧ ] | [ ė ] | [ i ] | — | [ u̇ ] |
|---|---|---|---|---|---|
| Example | imȧge | bėgin | lily | — | bu̇sy |
Note: the light sound has a dot added above and is always pronounced as /i/.

| Weak sound | [ å ] | [ e̊ ] | [ i̊ ] | [ o̊ ] | [ ů ] |
|---|---|---|---|---|---|
| Example | åbout | ope̊n | evi̊l | pro̊pel | sůpply |
Note: the weak sound has a ring added above and is always pronounced as /ǝ/.
Consonant Letters and Common Consonants
Through the pronunciation of the 26 letters, one can master 16 consonants:
[b], [d], [f], [j], [ch], [k], [l], [m], [n], [p], [r], [s], [t], [v], [w], [z]
| A | B | C | D | E | F | G |
|---|---|---|---|---|---|---|
| [ ā ] | [ bē ] | [ sē ] | [ dē ] | [ ē ] | [ ef ] | [ jē ] |
| H | I | J | K | L | M | N |
| [ āch ] | [ ī ] | [ jā ] | [ kā ] | [ el ] | [ em ] | [ en ] |
| O | P | Q | R | S | T | |
| [ ō ] | [ pē ] | [ kū ] | [ àr ] | [ es ] | [ tē ] | |
| U | V | W | X | Y | Z | |
| [ ū ] | [ vē ] | double-[ ū ] | [ eks ] | [ wī ] | [ zē ] |
Note: [j] is pronounced /dʒ/; [ch] is pronounced /tʃ/, which differs from the ch of Chinese pinyin.
Two-Vowel-Letter Combinations
Whichever letter bears the horizontal line above is read with that letter’s open sound.
| -A | -E | -I | -O | -U | |
|---|---|---|---|---|---|
| A- | [ āi ] | [ ãu ] | |||
| E- | [ ēa ] | [ ēe ] | [ ēi ] | [ eū ] | |
| I- | [ iē ] | ||||
| O- | [ ōa ] | [ oi ] | [ oo ] | [ ōu ] | |
| U- | [ ūi ] |
Note: oi, oo, and au are read according to neither the first nor the second letter; they must be memorized separately.

Note: to effectively distinguish multiple sounds, three more symbols are introduced — the tilde (∼), the backslash (∖), and the caret (˄) — for differentiation.

Vowel Letter + R
Open Sound + R
| Open sound + R | [ ār ] = [ er ] | [ ēr ] = [ ir ] | [ īr ] | [ ōr ] = [ or ] | [ ūr ] |
|---|---|---|---|---|---|
| Example | cāre | hēre | fīre | fōre | dūre |
Note: when an R sound follows immediately after an open sound, since the R sound involves a retroflex curl, the open sound changes automatically. IPS annotates the sound before the change, while IPA records the sound after the change; the two produce the same result.
Closed Sound + R
| Closed sound + R | [ er ] | [ or ] |
|---|---|---|
| Example | where | fork |
Vowel Combination + R
| [ āir ] = [ er ] | [ eār ] = [ er ] | [ ēer ] = [ ir ] | [ ēar ] = [ ir ] | ||

Common Suffix Pronunciations
The pronunciation rules for -ed and -s/-es are fixed; although this book gives distinct annotations, they may, for simplicity, be left unmarked.
Some other suffixes, such as -ly, -ous, -ity, etc., are pronounced according to the rules; although this book annotates them all, since their pronunciation is uniform, they may for simplicity be left unmarked.
The -ed Suffix
| -ed pronunciation rule | Example |
|---|---|
| After voiced consonants and vowels [𝕖d] ⟹ [d] | call𝕖d, borrow𝕖d, mov𝕖d |
| After voiceless consonants [𝕖ḋ] ⟹ [t] | ask𝕖ḋ, finish𝕖ḋ, help𝕖ḋ |
| After the [t] sound [ėd] ⟹ [id] | wantėd, startėd |
| After the [d] sound [ėd] ⟹ [id] | needėd, countėd |
The -s/-es Suffix
| -s(-es) pronunciation rule | Example | |
|---|---|---|
| After consonants | after [s], [z], [sh], [s̃], [ch], [j] sounds add -es, pronounced [ėṡ] ⟹ [iz] | glassėṡ, buzzėṡ, washėṡ, teachėṡ |
| after voiceless consonants add s, pronounced [s] ⟹ [s] | books, typ𝕖s | |
| after voiced consonants add s, pronounced [ṡ] ⟹ [z] | bagṡ, lin𝕖ṡ, besid𝕖ṡ | |
| After vowels | after the letter o add -es, pronounced [𝕖ṡ] ⟹ [z] | tomato𝕖ṡ, potato𝕖ṡ, do𝕖ṡ |
| change -y to i and add -es, pronounced [𝕖ṡ] ⟹ [z] | ladi𝕖ṡ, fli𝕖ṡ | |
| otherwise pronounced [ṡ] ⟹ [z] | newṡ, dayṡ, boyṡ, beeṡ |
Special Suffix Pronunciations
Some commonly used suffixes have rather special pronunciation, but the pattern is the same; simply memorize them. For simplicity, this book omits phonetic annotation for them.
| Special suffix | Pronunciation | Example |
|---|---|---|
| -sion, -tion | -sho̊n | impression, nation |
| vowel letter + -sion | -s̃o̊n | vision, decision |
| -s-tion | -s-cho̊n | question, suggestion |
| -sure | -shůre | pressure |
| vowel letter + -sure | -s̃ůre | pleasure, measure |
| -dure | -dgůre | procedure |
| -ture | -chůre | picture, culture |
| -tiate | -shiāte | initiate, negotiate |
| -tial | -shål | partial |
| -tuous | -chūo̊us | virtuous |
| -cious | -sho̊us | delicious, precious |
| -cial | -shål | official, racial |
| -ceous | -sho̊us | herbaceous, curvaceous |
| -cient | -she̊nt | ancient |
| -ciency | -shency | efficiency, proficiency |
Silent Letters
Silent letters may be indicated in various ways — strikethrough, slashes, dots beneath, etc. For prominence, this book uses double-struck (blackboard bold) letters. If the learner has already memorized these silent letters, they may be left unmarked.

Silent Vowel Letters
Since words ending with a silent e make up a large proportion, for convenience the silent letter e at the end is not marked; only the silent letter e situated in the middle of a word is marked.
For example: nam𝕖ly, chang𝕖able, h𝕖art, for𝕖in, for𝕖iner, pig𝕖on, g𝕦itar, q𝕦eue, fr𝕚end
