A careful review before you share

How to check IPA textwithout changing the sounds you mean

Paste a transcription, inspect each finding and choose only changes that fit your intention. A text check can improve a file without deciding how anyone pronounces a word.

Copied IPA can contain a hidden space, a mismatched bracket or a familiar-looking character with a different code. The useful response is a careful review of the text and its purpose. This example distinguishes an accidental text artifact from optional notation decisions.

THREE DELIBERATE TEXT CHOICES
Original text

[gɛt​ ə:]

Reviewed text
[ɡɛt əː]
The original contains U+200B ZERO WIDTH SPACE after t. The downloaded result removes that one hidden character and uses the chosen IPA g character and triangular length mark. These changes are specific to this exercise.
  • The ordinary visible space before ə remains.
  • The g replacement is an optional consistency choice.
  • The colon becomes ː only because length is intended here.

Clean up IPA text

Load a small example you can inspect

Open IPA text checker and select Try an example. Your IPA text contains [gɛt ə:] with an invisible zero-width space after t. Leave Show optional g, r and colon conventions selected so that you can examine all three decisions in this exercise.

Text inspection provides a second view of the same source. A flagged invisible character appears as a visible U+ code label, which helps you locate something you cannot otherwise see. The label is a preview aid; it is never inserted into the editor, clipboard or download.

The editor accepts up to 10,000 characters. Checks update as you type. You can use your own transcription, but keep an original copy when the exact supplied text matters. The checker does not silently rewrite or normalize it.

Remove the accidental invisible character

Find the card titled Invisible zero-width space. Its U+200B code identifies the underlying character. Select Show in text to focus its range in the editor, then choose Remove this character. The visible space before ə should remain because it is a different character.

Invisible controls are not universally wrong. A joiner or directional control can serve a legitimate purpose in a mixed-script document. The explanation gives you the option to retain it. In this short IPA-only exercise, the zero-width space was deliberately inserted as an artifact to remove.

The tool makes a literal change at the reported range rather than running a global search-and-replace. This matters when similar-looking characters occur elsewhere for different reasons. The character location also remains reliable after an astral symbol such as an emoji, whose internal string length differs from a simple letter.

Example
U+200B → removed at this location

Resolve the notation choices yourself

Next, read Choose a consistent g character. Both g and ɡ can represent the IPA voiced velar plosive. For this example, select Use IPA ɡ here to match the chosen encoding in the final text. In another document, Keep as written may be the better choice.

Read Colon or length mark? The ordinary colon is punctuation; ː is the IPA triangular length mark. This exercise intends length after ə, so select Use length mark ː here. Do not make the same replacement in a label such as “Example:”, where the colon has its ordinary role.

The optional r hint follows the same principle but can change the intended sound: r denotes a trill and ɹ an approximant. It would be a mistake to replace every r automatically merely because the document concerns English. Turn off the convention hints when they do not help your task; structural checks remain active.

Example
[ɡɛt əː]

Check the counts and test undo

Code points counts encoded Unicode characters. Text clusters groups characters according to the browser’s segmentation rules. Combining marks counts separate combining characters in the source. These figures can differ for a sequence such as a followed by a combining tilde.

None of these counts establishes the number of phonemes. A tie-bar sequence, a diphthong or a specialist notation can need an analysis that a Unicode text checker does not perform. A font can also shape the same underlying sequence in different ways.

Select Undo change once. The last tool change is reversed, bringing the colon back if the length-mark replacement was your final action. Apply that choice again to restore the reviewed result. Tool undo retains up to 30 states on the page; typing a manual edit begins a new review and clears this tool-specific history.

Example
ã = 2 code points, 1 displayed text cluster

Save the reviewed text and its context

When you have accepted or deliberately kept the remaining findings, the status says there are no remaining findings in this check. Read that literally: it does not certify the pronunciation, accent or linguistic correctness of the transcription.

Choose Download text. Open i2speak-reviewed-ipa.txt in a Unicode-capable editor and compare it with [ɡɛt əː]. The file should contain no U+200B character, should still contain the visible space, and should use the characters you selected. Copy text provides the same current source for direct transfer.

For a class or professional record, keep the relevant context with the transcription: the intended variety, source and notation conventions. If you are reviewing someone else’s file, explain which edits concerned hidden text and which were a deliberate notation choice. A clean character stream is one useful stage of review, not a substitute for phonetic analysis.

Decide what the text is supposed to express

A structural issue or a convention?

A mismatched closer or unattached combining mark asks you to inspect structure. g, r and colon hints ask what notation you intend. Neither category authorizes a blind rewrite.

An unfamiliar symbol or an invalid one?

The checker uses a core IPA set. Specialist symbols, digits and explanatory labels can be intentional even when flagged. Keep them when the task requires them.

A character count or a sound count?

Use the counters to understand the encoded text. Determining the number of phonemes or segments requires an explicit linguistic convention beyond these Unicode counts.

TRY IT YOURSELF

Keep a valid trill and repair a bracket

Enter [r). Keep the r because this exercise intends a trill. Repair the closing bracket so that it matches the opening square bracket. Explain why only one text replacement is needed.

Compare with the model answer
[r]

The bracket repair changes ) to ]. Keeping r preserves the intended trill; replacing it with ɹ would change the phonetic symbol rather than correct a text artifact.

Common questions

Why does the checker offer to change a valid IPA character?

The optional hints explain conventions and possible intentions. They are not automatic error labels. Both g forms can represent the velar plosive; r is a valid trill. Keep the original when it is appropriate.

Can the preview’s code labels appear in my exported text?

No. Preview labels for invisible characters are display aids. Copy and download use the actual editor contents, including any original character you chose to retain.

Why does it flag a label or an extended phonetic symbol?

Its character rules cover a core IPA set. Other useful text can fall outside that set. Review the purpose and use Keep as written when it belongs in the document.

Does no remaining findings mean the transcription is accurate?

No. It means the current text-checking rules have no remaining findings. The tool does not analyze speech, determine an accent or evaluate whether the symbols match a speaker.

Can I undo a suggestion?

Yes. Undo change restores the previous text after a tool change, up to 30 states on the current page. Manual typing starts a new review and clears that tool-specific undo list. Save an original when you need a lasting record.
