How do you hear the pronunciation of a word while watching a video?
YuzuLingo · Nov 1, 2026
Hover-to-lookup tools can play a recording or text-to-speech when you click the speaker icon on the dictionary card. For Japanese, many tools pull from JapanesePod101 or Jisho. For other languages, Wiktionary and Lingua Libre host thousands of native-speaker recordings that a browser extension can fetch on demand.
Why hearing the word matters
Reading a definition tells you the meaning. Hearing the word teaches pitch accent, stress, vowel quality, and connected speech. Languages like Japanese and Mandarin have pitch patterns that change meaning. Listening once while you learn the word helps the sound stick.
Recorded audio vs text-to-speech
Recorded audio from a native speaker is the gold standard. TTS is a fallback when no recording exists. Modern browser TTS is decent for common words, but it can mispronounce names, rare vocabulary, and words with multiple readings. A good tool tries recorded audio first and falls back to TTS only when needed.
Sources by language
Japanese: JapanesePod101 and Jisho host free audio for thousands of headwords. Chinese, Korean, Spanish, English, and other languages: Wiktionary Commons and Lingua Libre have crowd-sourced recordings under open licenses. Coverage varies by language and word frequency.
Fallback to on-device TTS
When no recording exists, the browser can speak the word using the operating system voices. macOS, Windows, ChromeOS, and Android all ship with multiple language voices. Quality depends on which voices you have installed and how the tool passes the text.
How this works on burned-in subtitles
First OCR turns the pixels into text. Then you hover the word to open the dictionary popup. The popup fetches audio for the headword when you press the speaker. The same flow works on soft subs, transcripts, or any other text the extension can scan.
