Pair this tool with study-roadmap articles and a shadowing method for better practice results.
Text-to-speech on its own is not practice. What works is the loop: hear the model, say it out loud, then find the gap. These four steps are that loop.
1. One sentence at a time
Paste a single complete sentence, not a paragraph. The hard part of shadowing is the melody of the line, and once a sentence runs long you are only chasing words.
2. Listen first, without reading
Play it three times with your eyes off the text. Listen for where it pauses, which word is stretched, whether the ending rises or falls — the things a textbook cannot mark.
3. Speak over the audio
From the fourth play, talk along with it rather than waiting for it to finish. Only when the two voices overlap can you hear where you rush and where your pitch is off.
4. Record yourself and compare
Record on your phone and play both back. The biggest gap is usually not the individual sounds — it is where you pause and what the sentence ending does.
Paste sentences from whatever you are reading and shadow them, or write them down from listening. A textbook CD runs at a fixed pace; here you can regenerate one line as often as you like without hunting for it on a track.
Pairs that differ only in length — おばさん / おばあさん, きて / きって — look almost identical on the page and are obvious the moment you hear them. Paste both and listen back to back.
Paste the introduction you have prepared and listen for linking and stress placement. English rhythm rides on stress, and reading word by word sounds nothing like speaking.
Say one thing in Japanese and then in English, and listen to them in sequence. The two languages pause in completely different places, and alternating makes each rhythm audible.
Yes. A download link appears under the player once the audio is generated. Files are MP3, so you can keep them on your phone and review offline.
One or two sentences works best. Longer input will generate, but past two sentences shadowing becomes impossible to keep up with, so the practice suffers.
Mostly, but words written the same and read differently — 行った can be いった or おこなった — depend on context, and a short sentence may not give enough of it. Writing the reading in kana gets you the pronunciation you want.
Not yet. If it runs too fast, slow it with your player's own speed control first, then go back to full speed once you can keep up.
Neither. The tool runs in the browser with no sign-up and no usage limit.
Yes, it is the same speech service. The sentence audio inside the apps and the files generated here come from one engine, so they sound the same.
