English to IPA Converter

The International Phonetic Alphabet (IPA) is a standardized system of phonetic notation developed by the International Phonetic Association. It uses a set of unique symbols to represent each distinct sound (phoneme) in spoken human language. Unlike regular English spelling—which is notoriously inconsistent (think "through," "though," "tough")—IPA provides a one-to-one correspondence between symbols and sounds, making it an invaluable tool for linguists, language learners, actors, and speech therapists.

The two major standards are General American (GA) and Received Pronunciation (RP, British). Key differences include:

• Rhoticity: GA preserves /r/ sounds in all positions (e.g., "car" = /kɑr/), while RP drops /r/ after vowels unless followed by another vowel (e.g., "car" = /kɑː/).
• Vowel shifts: Words like "bath" use /æ/ in GA but /ɑː/ in RP. "Hot" uses /ɑ/ in GA but /ɒ/ in RP.
• Flapping: In GA, /t/ between vowels often becomes a flap [ɾ] (e.g., "butter" ≈ /ˈbʌɾər/), while RP maintains a clear /t/.
• Vowel length: RP distinguishes long and short vowels more systematically (e.g., "cot" /kɒt/ vs. "caught" /kɔːt/).

This converter uses a built-in pronunciation dictionary with thousands of the most common English words, providing highly accurate IPA transcriptions for everyday text. For words not in the dictionary, it applies rule-based phonetic inference using common English spelling-to-sound patterns. While the rules handle most cases well, English has many irregular pronunciations, so uncommon or foreign-derived words may have slight inaccuracies. The tool works entirely offline in your browser—no data is ever sent to a server.

Absolutely! This converter is an excellent resource for ESL/EFL learners. By seeing the IPA transcription alongside the original text, you can:

• Understand exactly how each word should be pronounced
• Identify silent letters (like the "k" in "knee" /niː/)
• Recognize stress patterns from the primary stress marker (ˈ)
• Compare American vs. British pronunciations side by side
• Use the "Read Aloud" feature to hear the text spoken with your browser's speech synthesis

We recommend pairing this tool with audio resources for the most effective learning experience.

• ˈ (primary stress marker) — placed before the stressed syllable (e.g., /ˈwɔːtər/ = WA-ter)
• ˌ (secondary stress marker) — placed before a syllable with weaker stress
• ː (length mark) — indicates a long vowel (e.g., /iː/ in "see" vs. /ɪ/ in "sit")
• . (syllable break) — separates syllables in some transcription styles
• ˜ (nasalization) — indicates a nasalized vowel (rare in English transcriptions)
• Slashes / / enclose phonemic transcription (broad), while brackets [ ] enclose phonetic transcription (narrow). This tool uses slashes for broad transcription.

Yes, completely. All conversion happens locally in your browser using JavaScript. Your text never leaves your device, is never sent to any server, and is never stored or logged. This also means the tool works offline—once the page is loaded, no internet connection is required.

The "Read Aloud" feature uses your browser's built-in Web Speech API (speech synthesis), which is a separate system from our IPA transcription engine. The speech synthesizer may have its own pronunciation rules, accent, and intonation patterns that don't always align perfectly with formal IPA transcription. Think of the IPA output as the idealized, dictionary-standard pronunciation, while the speech synthesis provides a practical spoken reference. For the most accurate spoken model, we recommend consulting native speaker recordings alongside IPA transcriptions.

You can type IPA symbols using:
• Online IPA keyboards (search "IPA keyboard" for free web-based tools)
• IPA input methods built into some operating systems (macOS has an IPA keyboard layout in System Preferences → Keyboard → Input Sources)
• Character Map / Character Viewer utilities on Windows and macOS
• Copy-paste from this tool's output (use the Copy button!)
• LaTeX with the tipa package for academic documents
