Is there a Chrome extension that checks my pronunciation?

Yes, a few, and they work differently. TonePerfect has five free extensions (Chinese, English, Japanese, Korean and French AI Pronunciation Trainer): select text on any page, right-click, and it opens on toneperfect.app, where you record it and get a score for every word and every sound. For English only, TalkDrill scores the sentence you highlight word by word, also on YouTube subtitles; Pronuncia gives sound-level feedback in a card on the page, with a free account; and Phonicly.ai scores single words against an American accent. Many other “pronunciation” extensions only read text aloud.

Facts (checked 30 October 2026)

  • TonePerfect publishes five free Chrome extensions: Chinese, English, Japanese, Korean and French AI Pronunciation Trainer, all live on the Chrome Web Store.
  • Each one adds a right-click item for selected text and a popup with a text box; the text opens on that language’s practice page on toneperfect.app, where the recording is scored.
  • The extensions ask for one permission, context menus: no access to the pages you visit, no content scripts, nothing stored by the extension.
  • The practice page gives a few scored takes a day for free, with a score for each word and each sound and the weakest sound named.
  • Spanish, German and Russian have the same practice page on toneperfect.app but no extension yet.

TonePerfect’s five extensions

All five work the same way. Highlight a word, a line or a sentence on any website, right-click and choose the TonePerfect item. The practice page opens with your text, you press record, and you get a 0–100 score for the take, each word and each sound. The popup also has a text box and quick-practice tiles for each language’s signature sounds. The scoring happens on the website, not in the extension, which is why the extension needs no access to the pages you read.

Other extensions that score your speech

  • TalkDrill (English)

    Highlight a sentence on any site, or shadow YouTube videos line by line, read it aloud and get word-by-word feedback with an overall clarity score. 5 free checks a day without an account, 10 when signed in. Chrome Web Store

  • Pronuncia (English, for Spanish speakers)

    Highlight English text up to 100 characters and practise it in a card on the page, with feedback “down to the level of individual sounds”. Built around Spanish-to-English sound patterns; a free Pronuncia account is needed for AI feedback. Chrome Web Store

  • Phonicly.ai (American English, single words)

    Select a word, see its definition, hear it in an American accent, record yourself and get a score. Phonicly also sells a full American-accent course on its website. Chrome Web Store

Extensions that help you hear, not get checked

Hearing a word is useful, but it does not tell you whether you said it right. For that, the tool has to record you and score the recording.

  • Check Pronunciation

    An independent extension (not by ELSA) that opens the word you select on ELSA Speak’s pronunciation site; words only, last updated October 2024.

  • Speakerly: Read Aloud & Vocabulary Builder

    Reads pages aloud, translates and saves words; the speaking drills for saved words are in its mobile apps, not in Chrome.

  • Pronouncey

    Shows how English words are said in real-life video clips. Listening, not scoring.

No extension needed

Every TonePerfect checker also works without installing anything: paste your text into the sentence checker for English, French, Japanese, Korean or Mandarin, or the practice page for any of the eight languages.
